Outboard Boat Motor Guide: Everything You Need to Know

Walking through the boat dealership is an exciting experience. From bay boats to bowriders, cabin cruisers, and yachts, dozens of boat models are available to suit any pastime out on the water, from fishing to watersports.

While most of us focus on the boat we like, few new owners take the same amount of time selecting the right motor for their vessel. The outboard engine is the most common propulsion system for smaller watercraft up to 40-feet.

The outboard sits outside of the boat, hanging from the transom, which is the cross-section at the vessel’s stern. Outboard motors are available for leading manufacturing brands like Honda, Yamaha, and others. They come in various capacities to suit the size of your boat and your activities out on the water.

Choosing the right outboard motor for your boat is essential to getting the most value from your boating experience.

If you choose a low-powered motor, you’re not going to have the performance you need for watersports of navigating rough waters. Too high a capacity means that your boat won’t be able to enjoy the full operating potential of the engine.

We decided to put together this post to give you everything you need to know about choosing the right outboard motor for your boat.

Two-Stroke or Four-Stroke – Which Is the Better Choice?

Outboard motors are available in two-stroke and four-stroke models. The industry seems to agree that the four-stroke motor is the better choice for any boat. However, if we dig into the tech behind these engine configurations, the consensus seems to disappear, and there are several advantages to fitting your vessel with a two-stroke motor.

With a four-stroke motor, you’re getting a similar design to what you expect in a car engine. The engines operate on gasoline, with oil circulating through the system to lubricate the working parts motor.

Two-stroke motors operate on a blend of gasoline and oil, feeding the oil/gas fuel mixture through the carburetor or injectors into the cylinders through intake valves. Carb-based models are somewhat inefficient, and up to 30% of the fuel and oil mix entering the engine escapes unburned.

As a result, manufacturers moved towards direct fuel injection systems to enhance the efficiency of these engines. These systems spray the fuel into the combustion chamber using precision injection timing, with the piton covering the exhaust valve to prevent any fuel escape, improving the motor’s efficiency.

The four strokes per engine cycle, exhaust, and intake occur separately with four-stroke motors. DFI systems tend to be markedly more efficient than two-strokes due to the improved cycling of the pistons and computer management over the valves.

However, it’s important to note that the improvements in fuel injection and engine technology mean that the new generation of two-strokes is almost as efficient and quiet as four-stroke motors.

An example is the Evinrude E-TEC two-stroke DFI motor. This engine injects fuel at twice the speed of standard models, adjusting fuel delivery and the oil-gas mixture required by the onboard engine management system.

The result is an engine with all the power and performance of a four-stroke while running far quieter than traditional two-strokes.

The general reason behind using a two-stroke is that it’s more affordable than the four-stroke, and it offers more power due to the two-piston cycles per engine cycle. However, recent tech developments on four-strokes improve the power and performance of the four-stroke while maintaining efficiency and quiet-running.

As a result, the decision between choosing a two-stroke or four-stroke motor is now a function of what you want to do with the boat and your budget. We all want a four-stroke, but some of us might not have the extra money for it.

With modern DFI two-stroke engines, you get a motor that offers all the performance and efficiency of a four-stroke, with the speed and power you need for powerboating and watersports.

Key takeaways

• Two-stroke DFI engines offer you a lighter motor with almost the same efficiency and quiet-running capability as a four-stroke.
• While four strokes are generally quieter, the DFI two-stroke advancements mean that they run at nearly the same decibel output.
• Two-strokes provide the motor with a better holeshot, but four-strokes are closing the gap to gain the same power and performance as DFI two-strokes.

Buying Your Outboard Motor – New or Used?

Like buying a car, you have options to choose a new motor or buy pre-owned engines. When you’re at the dealership, it’s tempting just to add a new motor to your purchase, but you might find a pre-owned motor for half the price, offering you the same performance and service life as a new engine.

However, when you’re buying pre-owned motors, you’ll need to know what you’re looking at when assessing the engine.

If you don’t have any mechanical experience working on boat motors, we suggest you bring along a qualified and experienced mechanic to the viewing. They’ll assess the condition of the engine before you close the deal.

Calculating Outboard Motor Capacity for Your Boat

If you have a 40-foot cabin cruiser, your motor capacity is going to be much higher than for a 16-foot bowrider. So, how do you choose the right motor capacity for your vessel? The sales agent will likely recommend the right motor for your boat if you’re buying from the dealership.

However, if you’re searching on the used market, you’re going to need to do a quick calculation to figure out the right motor capacity for your vessel.

You’ll need to start the calculation by converting the vessel’s weight from tons to pounds.

So, if your bowrider has a dry weight of 1.1-tons, it works out to 2,500-lbs.

For the average performance model boat, like a center console or a bowrider, you’re going to need approximately one horsepower (HP) for 25 to 40-lbs of weight.

Take the boat’s weight in pounds and divide it by 200 (for a 200-HP engine). So, for our 2,500-lbs boat, we get approximately 12.5-lbs of horsepower per pound with a 200-HP engine.

2,500 divided by 125 is 20-HP per pound, and the lower the figure, the higher the engine’s performance. So, dividing 2,500 by 300 gives us 8.33 Hp-p/lb, making for a fast boat that’s ideal for watersports and speed boating.

Why Should I Choose a Larger Outboard Engine?

The motor capacity defines the boat’s power and its performance on the water. If you’re facing a choice between an engine that’s slightly under the recommended capacity or slightly over, we recommend going with the higher power to avoid disappointment out on the water, especially if you’re into watersports or speed boating.

If you have a pontoon boat or slow-moving cruising vessel, then the lower capacity is the better choice as these models do not have the design for high-speed operation. Overall, we recommend going with the higher power if you enjoy watersports and offshore fishing and lower capacity option for inland water bodies and cruiser boats.

What are the Top Features to Look for In an Outboard Motor?

After calculating the right motor capacity of your boat, it’s time to assess the engine’s features. Here’s what you need to look for when choosing the right motor for your vessel.

Electronic Ignition

Ripcords are so 1990s. Today, all the leading motor models come with an electronic start. You either turn a key or push a button and the motor springs to life, with no ripcords required.

When the water is rough, and you need a fast start, electronic ignition can mean the difference between taking water onboard or making a quick escape from the weather conditions.

Power Tilting

Choose a motor offering you power tilting of the engine. This feature electronically lifts the propellers out of the water by tilting the motor forward at the push of a button.

It’s a great feature for fishing in shallow waters to stop the props from agitating the sediment on the bottom, and it also helps with lifting the motor when you’re launching or trailering the vessel.

Power Thrust

This feature is like a “nitrous-oxide canister” in a sports car. It increases a temporary surge of power to the motor to combat strong currents and winds out on the water. The thrust increases the forward propulsion by up to 15% and the reverse propulsion by 60%.

The power thrust also assists with the maneuverability and steering of the boat, making it easy to reach top speeds while maintaining full control of the vessel in demanding water conditions.

Is A Dual Outboard Setup the Best Choice?

Take a drive through the marina, and you’ll see boats with single, double, or even triple outboard motor configurations.

Typically, these engines feature on boats that take to deep water for sports fishing trips. In most cases, the captain won’t use two or three motors simultaneously; they keep the auxiliary motors as a backup in case of mechanical failure of the primary engine while they are out at sea.

Installing a dual-motor configuration to your boat also makes docking that much easier. The propellers revolve in separate directions, allowing for the easy repositioning of the vessel as you approach the dock or slip.

However, if you install dual or triple motors to your boat, it will double or triple the expenditure you make on the motor purchase. You’ll have to decide if the addition of extra engines offers you enough value to justify the increase in your budget.

If you have the budget, a twin outboard setup will always be the optimal choice for most boating applications. It’s important to note that a dual or triple configuration is only useful against mechanical failure if each motor has an independent fuel and power system.

You might find that it’s way more affordable to get a single motor and just upgrade your marine radio system so you can call for rescue if the engine breaks down while you’re out at sea.

Do I Need High-Octane Fuel for the Outboard Motor?

As high-compression motors arrived in the boating industry, early models would experience the fuel combusting too early in the combustion cycle. This pre-ignition problem, otherwise known as “spark knock,” was an irritating noise, and it also damaged the combustion chamber, scarring the cylinder walls and damaging the valve seats.

As a result, manufacturers included additives in fuel to slow the ignition until the spark plug was ready to ignite the fuel. So, today’s modern engines now operate better with high-octane performance fuels, allowing them to handle the higher compression rate.

However, the reality is that using high-octane fuel on your outboard motor isn’t the best choice – for your wallet. These high-octane fuels don’t add any additional performance to the outboard motor, and you’ll get the same power out of using 87-octane as you would with other grades on the 90s.

With the cost of fuel rising in the United States and some states seeing prices at over $4 a gallon, using a lower octane fuel will save you hundreds of dollars over the year.

How Do I Select the Right Propeller for My Outboard?

You can think of the propeller on your boat like the tires on your car; it’s where the “rubber meets the road” or, in our case, where the “steel meets the water.” Props are similar to tires in that they come in different designs for different purposes out on the water.

You have dedicated props for performance speed racing, watersports like wakeboarding, and increasing economy. If you’re purchasing your new motor for the dealer, ask them about the prop installed on the engine and the various prop options available.

Most dealers install efficient, mid-range performance props on their motors. So, if you’re buying a boat specifically for watersports, this prop might not be the best option for the task. However, you can negotiate with the dealer, and they’ll likely install any type of performance prop you want on the engine.

Propeller Basics

Fortunately, understanding propeller technology isn’t rocket science. Props change the pitch and diameter of the blades to suit different applications in the water. As you already guessed, the diameter refers to the size of the prop.

The pitch refers to the theoretical distance the prop needs to travel in a complete revolution, provided there is no slippage. The reason why you need to select the right prop for your boat comes down to the fact that motor manufacturers rate an engine’s horsepower at specific RPMs, setting the rpm range for the motor’s top-end operation.

However, the motor can only reach this top-end range if it has the right prop suited to the task. If the prop permits the engine to over-rev, you risk damage to the motor due to the high-revs creating a faster rate of wear and tear on the motor components.

Conversely, if the prop is too large, then the motor will struggle to reach top-end rpm ranges, creating another set of challenges for the engine that might damage its internal components.

Picking the right pop pitch ensures you get the best performance from the engine while protecting the internal components from damage. To test the prop., you’ll need to take the boat out onto the water and open the throttle to the full position.

When your engine runs over the max-rpm range, back off the throttle, reduce speed until the rpm gauge drops to the suggested rpm range recommended by the manufacturer. When you return to shore, check the pitch of the props.

You should have a drop of 200-rpm for each degree of increase in the pitch. Cupped props can reduce rotation by up to 200-rpm. Ask your dealer if they allow you to test the prop. Most dealers will agree, provided you return it to them undamaged.

As long as the propeller reaches the top-end range, but doesn’t exceed the max-rpm value, delivering wide-open RPMs to the bottom of the recommended range provides you with better performance in holeshots. Props offering RPMs toward the top-end of the range generate higher top-end speed.

What to Know About Boat Engine Propellers

The condition of the propeller is more important than the type of prop installed on the boat. Damaged propellers can cause problems with the normal operation of the engine, creating stress in the motor components that cause damage.

We recommend going with stainless steel propellers as they offer you the truest running performance and high strength levels. Aluminum is a cheaper material, sacrificing itself to provide the lower unit better protection.

Four-blade props beat three-blade models in the time it takes to reach planing speeds, midrange speeds, and they offer you better low-speed handling.

Easy Outboard Engine Maintenance Tips

When the motor isn’t in use, keep the fuel tank topped to reduce the chances of condensation building on the inside of the tank. If water gets into the engine system, it will require you to bleed the system to get the motor to start.

• Add fuel stabilizer additives to the fuel tank every time your refuel. It’s critical to do this with ethanol-based fuels to prevent separation and fouling of the fuel system.
• Inspect your propellers after each trip for damage, dings, pocking, and wear.
• Inspect the hoses and fittings to ensure there are no leaks.

Outboard vs. Inboard: Which Motor is Right for You?

Many family boats, including bowriders , deck boats and cabin cruisers , are offered with a choice of outboard or inboard power. When both options are available, is there a better choice between the two? Let’s take a look at inboard vs. outboard boat motors , and dig deeper into the advantages and disadvantages of each type of power.

Explore All Boat Motor Types & Brands

What are the Key Differences Between Inboard and Outboard Motors?

Family boats with inboard power are almost always equipped with a sterndrive (sometimes called an inboard/outboard or I/O) powertrain, which combines an automotive-type engine mounted inside the boat with a steerable and trimable drive unit mounted on the stern (the back) of the boat. The exception would be for a dedicated watersports tow boat , which has an inboard engine turning a propeller under the boat, with steering control provided by a rudder.

Sterndrives are currently offered from 200 horsepower to 430 horsepower, but many compact runabouts on the pre-owned market may be powered by a 130-horsepower sterndrive that is no longer in production. An outboard motor is a dedicated marine engine that is attached directly to the stern of a boat.

Outboards are available from tiny 2-horsepower kickers to 600 horsepower, but for family boating the range is typically 90 to 300 horsepower. As outboard motors have become more powerful, they are gaining popularity on larger cabin cruiser and day boats that once were always equipped with inboard engines. These may be rigged with three or four outboards that combined make more power than the biggest pair of sterndrive engines available, resulting in performance that was once unimaginable.

Initial Cost Comparison

It seems natural to make a cost comparison based on horsepower—a 250-horsepower outboard to a 250-horsepower sterndrive in the same boat—but it’s smarter to make that comparison based on performance.

In this example, a 200-horsepower outboard will usually match the performance of a 250-horsepower sterndrive, simply because the outboard weighs less, and because that weight is more efficiently positioned behind, rather than inside, the boat. This rule of thumb holds true as you move up and down the horsepower scale. However, even with less horsepower the outboard-powered boat will often cost a little more—2 to 4 percent—than a similar boat with a sterndrive.

Inboard vs. Outboard Maintenance Costs & Ownership

Because it will usually weigh less and be a more-efficient design, an outboard motor will typically deliver better fuel economy than a sterndrive. Both will require similar annual maintenance, except that in cold climates the cooling system of most sterndrive engines needs to be flushed with antifreeze solution, usually by a marine service center.

• An outboard is self-draining and many owners can accomplish their own off-season service.
• Sterndrives once had a reputation for being more prone to corrosion-related issues in salt water, but corrosion resistance is much improved on modern engines and outdrives, and many can be equipped with a closed cooling system that keeps most saltwater out of the engine.
• However, most sterndrives can not be tilted completely out of the water, while most outboards can clear the water when tilted all the way up. This is an advantage for the outboard if the boat is docked or moored full time in saltwater, as it prevents marine growth and corrosion from occurring on the drive.

Serviceability

Because the entire engine is outside the boat, an outboard is easier to service than an inboard. With the boat on a trailer you can simply stand next to the outboard.

Servicing the inboard requires working under an engine hatch, often in pretty cramped confines. When an outboard is damaged or simply worn out, it is relatively easy to re-power the boat with a new outboard. Repowering an inboard boat is also an option, but a more-challenging project.

• Boat Motor Maintenance & Engine Care Guide

Additional Pros & Cons

An outboard has many advantages over a sterndrive:

• It’s lighter, faster, more efficient, and easier to service;
• Because the entire engine is located outside the boat, there’s more room in the boat for seating or gear storage;
• A new outboard is cleaner, quieter and more powerful and feature-laden than the motors offered just a few years ago, all reasons they have become more popular on more types of boat.

A sterndrive does have some advantages, however:

• The drive unit is low on the transom, which permits a full-width boarding or swim platform that’s not cluttered by an outboard motor. This can really improve the lounging experience, and many people find this uncluttered look much more attractive.
• The sterndrive engine may also be covered by a padded sun lounge, another feature many owners appreciate.
• When equipped with a drive with forward-facing propellers ( Volvo Penta Forward Drive or MerCruiser Bravo Four ), the boat can be used for wakesurfing , an activity that’s not safe—or even legal on most waters—behind a boat with a traditional sterndrive or an outboard because of the proximity of the spinning propeller to the surfer. For many boating families, the ability to wake surf is reason alone to select an inboard with forward-facing props.

Either engine is a great portable with enough oomph to propel your dinghy adventures.

Types of outboards

The most common types of outboards seen on boats today are gasoline-powered internal combustion engines :

Internal Combustion Engines

Two strokes and four strokes

Two-stroke engines complete all cycles of engine operation—air and fuel intake, ignition or power, and exhaust in two strokes or revolutions of the engine pistons.

Four-stroke engines complete all of the steps of engine operation in four separate revolutions of the pistons.

Some benefits of a two-stroke are that it is simpler in design, and therefore a lighter, easier engine to maintain. The power stage occurs each cycle offering greater thrust in a smaller package than its four-stroke counterparts. The fuel efficiency, however, is greatly decreased and its emissions are increased by its gasoline-lubrication oil mixture, making it less environmentally friendly.

In fact, when the Environmental Protection Agency (EPA) was established in the US, policies regulating the emissions of engines were implemented and many manufacturers ceased making two-stroke outboards altogether. Some manufacturers recognized the desire for the lighter weight and higher horsepower demand. So they endeavored to use the same two-stroke technology in the same light package, but with emissions within the specs of the EPA requirements.

Four strokes, while having a more complicated, heavier design owing to more moving parts, are as a whole, more fuel-efficient, quieter, and more eco-friendly. With the growing demand for lower carbon emissions, technology has improved to provide those options in a more compact unit. Truthfully, if you’re willing to read the manual and take the time to look at your engine, the maintenance on a four-stroke engine is quite achievable.

Electric outboards

With increasing awareness about the effects of fossil fuel-powered products on the environment, coupled with the advancing technologies for electricity, solar power, and batteries, recent years have seen a greater demand for electric outboards.

Small/Portable

Horsepower Range: 2.3HP to 20HP

These little outboards are the ideal option as a primary means for propelling your dinghy , kayak, Jon boat , or even small sailboats.  The smaller HP options make great secondary or trolling motors for the fishing folk among you. They are pretty lightweight, making them easy to lift and stow. Some of the best options are as follows:

Choosing an Outboard

So you’re buying your first outboard, congrats!

There’s a lot of information and even more opinions out there on the best brand, size, and horsepower.

So, before you pull out your hard-earned money and give it to an outboard dealer, addressing the following topics for yourself will help narrow down your search and find the right outboard that suits your needs.

Intended Use:

One of the first determining factors to consider before purchasing your outboard is the vessel’s intended use. Are you using it on weekend fishing trips? Does it need to be capable of covering a lot of distance? Perhaps it will be used on a utility boat. Will it be used in freshwater or salt? Will it remain on your boat’s transom or does it regularly need to be removed and stored? Will it be required to move a lot of gear?

For cruisers, that includes cabin cruisers as well as some bow riders , efficiency and noise might be relevant.

Size and Weight:

This one seems obvious, but it bears examination. How much real estate does your boat transom actually have and what size engine or engines can you fit on it? If you desire more than one engine, which options have the best integrations for multi-engine controls? Will it require an outboard with the longer shaft option or a shorter one?

Center console boats operating in bigger surf need to consider this point. Take a look at the Boston Whaler boats–mostly equipped with Mercury engines–to see the profile for motor and purpose.

For portables: how much can you reasonably lift for engine transport and installation mechanically unassisted?

How Much Horsepower? 

While it is tempting to want to purchase the sleekest looking engine with the greatest horsepower, many boats will have a maximum horsepower safety rating. It is important to know this number when shopping as it is dangerous to exceed the vessel’s designed horsepower, and most dealers won’t knowingly sell you an engine that does.

Conversely, it’s important not to aim too small when choosing your engine’s horsepower compared to your boat’s maximum rating so you don’t lose efficiency.

Budget: What is your maximum budget? Taking into account the answers to the above categories, make a list of the outboards which provide the most value and are within your maximum budget.

Common outboard terminology 

Below are a couple of definitions to have an understanding of before making your outboard purchase. Knowing the details of an outboard’s specs and how they benefit you with how you intend to use your engine, will only aid you in making the best selection.

Gear Ratio : gear ratio is the number of crankshaft turns in relation to the number of prop shaft rotations. If an engine has a gear ratio of 2:1, it means that for every 2 rotations of the engine, the propeller turns one time. A 1:1 gear ratio means the prop shaft turns each time the engine does. While it might seem like you would want the prop to turn each time the engine crankshaft does, engines require reduction gear to maximize the torque and the efficiency of propellers based on their pitch and diameter.

Electronic Fuel Injection (EFI) : a batteryless method of injecting the appropriate fuel-air mixture directly into the piston chamber for ignition by the spark plug. This method of fuel injection increases the engine’s overall performance, reduces fuel consumption, and eliminates the need for a carburetor, which can get clogged and dirty.

Carbureted Engine: An engine that uses a carburetor to inject the proper mixture of fuel and air into the engine cylinders. While most newer engines have incorporated EFI, some traditionalists still prefer a carbureted engine for its easy troubleshooting and maintenance over a computer system.

Engine Displacement: this refers to the swept volume of the cylinders of an engine, usually measured in liters. Engine displacement is related to the amount of torque and horsepower an engine is capable of, as well it’s fuel economy. Larger engine displacement=more power (but also higher fuel consumption).

Taking care of the machine: Basic Outboard Maintenance

Regardless of what brand-name manufacturer you choose, the life expectancy of any internal combustion engine will greatly rely upon the quality and timeliness of its routine maintenance.

Take care before initial break-in and subsequent normal use to read the provided manual, and layout your engine’s maintenance schedule.

Some consumable items which should always be kept on hand are oil filters, manufacturer-recommended oil,  appropriately sized spark plugs, and fuel filters.

Some routine maintenance items which should be checked before they become a problem

Oil: Check the oil dipstick ideally every time the engine is run.  Look for changes in oil color, adequate oil level, and metal shavings or debris in the oil.

This is good practice, especially after an engine break-in period as gears and pistons straight from the factory will lose tiny metal particles from the friction created from running for the first time. These particles, if left in the oil can reduce the engine’s service life,

If the manufacturer suggests changing the oil every 100 hours, it may pay in the long term to halve that interval for the first oil change.

When changing the oil, precautions should be taken to avoid spilling oil into the environment.

Some tools to make this process easy and clean are a manual vacuum pump:

Or if working with a portable engine, remove the engine from the transom and place it on a service rack.

Ensure you have an appropriate container to catch the old oil as it drains as well as some petroleum product diapers and rags handy should you have an accidental spill.

Remove the oil drain plug on the side of the engine (see engine manual), just above the engine’s lower unit. Once removed, the engine oil will start to drain out into your waste oil container.

Once the oil is completely drained, replace the plug and tighten. Make sure to recycle your old oil at an appropriate facility. Most auto body shops provide this service.

With the plug securely in place, open the oil fill cap and place a funnel in the opening. Using a grade of lubrication oil recommended by the manufacturer, slowly fill the engine with oil. Do not exceed the capacity indicated in the manual.

Spark plugs:  The spark plug(s) is a common item that ought to be inspected and replaced at regular intervals. These little cylindrical pieces provide the tiny spark which ignites the fuel-air mixture during the ignition/power cycle of two and four-stroke engines.

There is one spark plug for each cylinder in a given engine. They are relatively inexpensive and it’s always good to have extras.

Over time, the plug can develop carbon build-up which can prevent the plug from sparking and the fuel from igniting. It’s one of the first places to look when troubleshooting “failure to start” and acceleration issues.

The picture below shows what the carbon build-up on a spark plug looks like with the plug removed from the engine.

In this case, just a small wire brush to clean the carbon was required to get the spark plug clean and the engine running again.

Gap distance: each engine has a specific distance between the ground electrode and the center required for proper ignition. If this distance is off, the power cycle will not function properly. Use a gap tool, feeler gauge, or caliper gauge to measure the distance and compare it to the manufacturer’s requirements.

In the case that the spark plug has worn and the gap distance has increased beyond the manufacturer’s ignition system specs, you can adjust the gap by gently bending the ground electrode (curved metal arm) to the required distance.

Spark plugs should be inspected every six months and replaced annually.

Flushing the Engine:

Saltwater can do a number on metal components and engine parts. And since most of the outboards listed above are water-cooled, if you operate your boat on the ocean, saltwater is run through that cooling system, inviting corrosion to start.

To prolong your engine’s service life, it is good to flush it with fresh water after each use in saltwater ideally, or before the boat will be taken out of service for an extended period.

Couplings to conduct a fresh-water flush can be purchased:

• West Marine

Just mount your engine on an outboard service rack such as these:

…Or leave it on the boat on a trailer out of the water.

Attach the flush coupling to the water intake on the engine’s lower unit.

Connect a garden hose to the coupling and turn it on.

Start the engine and let it run for several minutes, flushing the freshwater through its intake and internal components. Your engine will thank you!

Fuel maintenance: a gasoline engine will only run well if it is fed well. An often overlooked factor of engine maintenance is taking care of the fuel you put in your outboard. It’s easy to forget to treat your gasoline with a stabilizer when filling up, and if not used in a timely manner, the fuel can degrade and the engine will not function, or it will run rough.

If you’re able to, mix 50% or more fresh gasoline with the old gasoline to run your engine and use up the old gasoline.

Electrolysis: another factor that becomes an overlooked maintenance item is electrolysis. Electrolysis “refers to the passage of electricity through an electrolyte” ( Calder, 486 ). It can occur when two dissimilar metals are immersed and the current is passed through the metals leading to the transfer of electrons from the “less noble” metal to the “more noble” metal. The result is the corrosion of the less noble metal.

To combat this effect, manufacturers outfit their engines with a “less noble” metal attachments, usually made of zinc, as a “sacrificial anode.” As electrolysis occurs, the zinc corrodes, rather than the important components of your outboard engine, like your propeller and prop shaft .

In the picture above, you can see the early stages of corrosion on the zinc/sacrificial anode located above the propeller on an outboard motor.

For the sacrificial anodes to work, they need to have contact with naked metal. There must be no paint separating contact between the zinc and the metal surface.

These zincs should be changed for new ones when the corrosion has gotten to an advanced stage.

Four Electric Boat Motors Compared

• By Randy Vance
• Updated: September 17, 2020

Electric marine propulsion is rapidly advancing in market share while providing a fun and unique boating experience not available from internal combustion power.

Electric Motors Then

You might be surprised to learn that electric boats have been around since 1838. Inventors from Prussia, England and America began making vessels with lead-acid batteries—tons of lead-acid batteries per vessel—to move passengers quietly and efficiently. But the internal combustion engines invented in the late 1800s were more powerful and convenient, and with the exception of Elco electric motors, electric power fell away in popularity. In 1934, Minn Kota manufactured the first electric outboard. Then, in the 1960s, bass tournament fishing popularized big-horsepower gas engines for speed, and electric trolling motors for precise boat handling. You might say the fishermen were ahead of the curve by about 60 years on hybrid boats.

Electric Motors Today

We are focusing on production models that can be easily installed by a do-it-yourselfer or OEM without special training. Lithium-ion batteries can be volatile if not properly installed, so some companies require their trained tech to do that.

Electric outboards are expensive, and while we’ve listed the purchase cost, the batteries available are too numerous to name or price, and can cost more than the motor.

A mathematic equation easily converts kilowatt-hours to horsepower, and our math revealed the calculated horsepower to be considerably less than the equivelant horsepower suggested by manufacturers.

Torqeedo provides completely integrated motor, battery and controls. Electronically controlled systems give its motors greater range per battery capacity and, similar to a fuel gauge, help operators conserve energy when needed or tell them when they can splurge on maximum throttle. The batteries are provided by BMW, but it is Torqeedo’s control system that manages output, heat and recharge operations to protect and optimize battery capacity and motor performance.

Range of Power: Outboards from Ultralight 403 at 400 W (about 1 hp) to Deep Blue at 50 kW (about 80 hp equivalent with 20 percent hole-shot boost), and inboards up to 100 kW (about 135 hp).

Most Popular Motor: Torqeedo’s Cruise 10 ($8,999) puts out 10 kW, or about 14 hp, but performs comparably to a 20 hp outboard thanks to Torqeedo’s software. In remote control, it is popular among pontoon boaters in particular, and commonly installed on pontoons used on neighborhood lakes requiring electric propulsion. Through digital controls, peak output is boosted beyond nominal output for a short time to improve acceleration at the hole shot, then returns to nominal output for optimal heat, range and speed control. A side- or top-mount controller—akin to the throttle—will cost $1,399, by the way.

Best Battery: The Torqeedo 48-5000 (5,000 Wh) lithium-ion battery ($5,159) is rated IP67 waterproof; connecting two or more in parallel extends the range.

Battery Compatibility: Compatible with any lithium-ion or AGM battery bank providing 48 volts, the Torqeedo can only operate in smart mode, measuring discharge, heat and other factors to dynamically manage power with Torqeedo batteries. With nonproprietary battery banks, Torqeedo motors mathematically, and less accurately, estimate range and consumption.

Chargers: The 2213 charger ($899) can recharge a 48-5000 battery in under 10 hours. It is rated IP65 water-resistant. The 2212-10 charger ($2,199) can recharge it in two hours.

Elco Motors

Elco has been building electric outboards for over 100 years—a figure that seems implausible to boaters who are beginning to see electric propulsion for the first time. The company’s engineering philosophy has remained the same: build plug-and-play systems, relying on battery power preferred by the customer, and design its motors to fit existing motor mounts, or provide standard transom clamps to make repowering simple and seamless.

Range of Power: Elco builds electric outboards with tiller or remote controls from 3.7 kW (about 5 hp) to 37 kW (about 50 hp). Elco’s inboards range from EP 6 to EP 100, with horsepower equivalents from 6 to 100.

Most Popular Motor: The EP 70 inboard ($15,995) can replace inboard diesel kickers and trawler motors, providing a top speed of 8 to 10 mph (7 to 8.5 knots) and a range of 23 to 41 miles. Its peak output is 51.5 kW (about 69 hp), and continuous output is 29.75 kW (about 40 hp). It needs nine 8-D 12-volt AGM batteries for a total of 108 volts. Lithium-ion batteries are also compatible in comparable volts and amps.

Best Battery: Battery banks from Lithionics are most commonly selected for new builds, and an EP-12 Victron AGM Deep Cycle 12V/220Ah bank is ideal ($5,409).

Battery Compatibility: Elco batteries are completely brand agnostic and connect with any quality battery bank providing the motor’s power demand. However, lithium-ion batteries still provide the most efficiency, along with full power to complete discharge. Even though their upfront investment is often more than double that of AGM batteries, the cost per charge is comparable while also lightening the boat and bringing better performance and range.

Chargers: The ElCon UHF3300 (1x) charger (starting at $825) takes three to four hours to restore battery banks, and the PFC 5000 fast charger reduces the time to two to three hours.

ePropulsion

This company boasts five electric propulsion systems engineered at the Hong Kong University of Science and Technology, and entered the market in 2013. HKUST is also known as the incubator of many electronic products, including the DJI drone. Persistent engineering has brought new innovations to the marketplace.

Range of Power: The smallest offering from ePropulsion is a strap-on stand-up-paddleboard motor. Mainstream power includes two large outboards boasting 1 kW (about 1.35 hp) and 3 kW (about 4 hp) power, two pod drives of the same output, and the most popular portable Spirit 1.0 Plus.

Most Popular Motor: The Spirit 1.0 Plus ($1,999 including charger) is ePropulsion’s top-selling motor, ideal for small vessels, square-stern canoes, tenders and more. It’s a 1 kW motor that the company says offers 3 hp equivalent power with an industry-first direct-drive brushless motor. That’s a quiet arrangement, making the motor lighter and more efficient. It’s got a 75-minute run time at full speed, making 22 miles on a quickly exchangeable, integrated and included floating battery. Take a spare battery ($899) for longer range.

The Navy 3.0, ePropulsion’s latest motor, is 3 kW, or about 4 hp, though ePropulsion claims 6 hp equivalence. It’s available in tiller-steered and remote-control models. Its direct-drive, no-gear-case motor was a breakthrough in electric outboards, using a brushless motor that produced less sound and drag, and increased power and efficiency, offering a more serene experience.

Best Battery: There are three E-Series 48-volt batteries offered: The E40 ($1,200) provides 2,048 Wh, the E80 ($2,000) provides 4,096 Wh, and the E175 ($4,000) offers 8,960 Wh. The data-cable connections in ePropulsion batteries give battery management, enhancing range and speed.

Minn Kota Motors

Minn Kota has been making electric outboard motors since 1934, and its first model was a gear-driven, transom-mounted motor with a tiller. As time progressed, it improved motors slowly until the tournament bass-fishing craze began in the early 1960s. In that time, the motors have been popular as primary propulsion for dinghies and utility boats used for tenders, or positioning the boat for casting.

Range of Power: Models today range from simple tiller- steered motors to digitally remote-controlled motors complete with autopilot features and smartphone compatibility. The Vantage is the company’s primary propulsion motor.

Most Popular Motor: The Vantage ($1,549.99) is not Minn Kota’s most popular motor, but it’s a top contender in the boat market where electric propulsion is desired or required. The tiller-steered Vantage is ideal for use as a kicker for trolling, or propulsion for a tender or small johnboat. The variable-speed motor is digitally controlled to manage and conserve power for optimum range. Forward, neutral, reverse, and power trim to raise it are easily accessible on the tiller of this 24-volt motor. For some reason, Minn Kota does not list specs such as amps, kilowatts or watt-hours.

Best Battery: Minn Kota doesn’t offer batteries, but the motor is compatible with any battery bank producing 48 volts.

Battery Compatibility: Lead-acid, wet-cell batteries are still the most commonly used for small electric motors, but AGM (absorbed glass mat) batteries are more durable, offer more charge cycles, and are quickly replacing wet-cell batteries. Lithium-ion batteries shave 75 percent of the weight of lead-acid batteries, deliver full power to total discharge, and are actually more economical per charge cycle in spite of a 100 percent premium over AGMs.

Chargers: An MK 345 PC Precision Charger ($449.99) provides three-bank charging at 15 amps per bank.
