Electric Sailboat Motor: Range, Cost, Best Kits for Conversion

Today, owning a completely green sailboat has been made possible with electric sailboat motors.

Imagine cruising with the silence of an electric sailboat motor and the ease of use with a simple press on the start button. What’s better is there are no exhaust fumes at all with significantly less maintenance.

It’s so appealing that a lot of sailing liveaboards have made their electric sailboat motor conversion.

However, some sailors are still on the fence, worrying about the range and price of the electric sailboat motor.

If you are one of them, you are in the right place!

This post will guide you through every aspect you need to know about electric sailboat motors to help you make an informed decision.

Besides, you will get professional insights on how to make the electric sailboat motor conversion for your own boat and learn the best electric sailboat motors (with honest reviews).

Electric Sailboat Motor: Confusion Explained

Can you go cruising with an electric sailboat motor? Can you put an electric motor on a sailboat? Are there any limitations?

Whether electric sailboat motors are a good fit for your boat is not a YES or NO question. Here we will explain your top worries with statistics and facts. That way, you can make a wise decision according to your situation.

You may hear some complaints about the batteries and range of the electric propulsion.

However, their experience may not suit electric sailboat motors.

In fact, even small electric engines work pretty well in many sailboats. That’s because most of the time, the wind can power the boat, and the motor is just used for docking or in rare times when there is no wind.

Therefore, it makes more sense to learn electric sailboat motor performance in real-world applications.

Here is a test report of a 3 HP electric sailboat motor on an RS21 racing sailboat:

As you can see, the small electric sailboat motor can run at 5.5 mph top speed for one hour continuously.

And there is a big difference in terms of range vs speed for electric sailboat motors:

If you lower the speed, the range and runtime can be greatly extended. The slower you go, the further you’ll get. For example, if you cut your speed in half, the electric sailboat motor can last 7 hours and go 20 miles within one charge.

That’s pretty sufficient if you use the electric yacht motor mostly for docking or as an auxiliary engine.

Faster top speed (and more range) is available with higher power electric sailboat motors depending on your specific requirements. Contact a specialist to design your electric sailboat motor solutions.

Also, don’t forget to get the electric sailboat motor with regeneration (See recommendations below).

That’s to say, when there is a lot of wind and you’re moving rapidly via your sails, they regenerate and store electric power on the batteries to keep you moving at other times. Solar recharging is also a plus.

Essentially, the range depends on how many batteries you have, so it’s not a limitation of electric sailboat motors but energy and batteries.

If you are still worried, you can offset this by getting a diesel generator, which is more efficient than a diesel engine. And it is a range extender when you need it, but for 90% of your motoring that you don’t need the range, you can rely on the electric sailboat motor.

Some of you might be concerned about the extra weight of the batteries.

In fact, an electric sailboat motor with lithium batteries weighs less than a diesel engine, particularly if you include the fuel weight.

If you want a lightweight electric sailboat motor solution, make sure you get one with LiFePO4 batteries . Compared with other marine batteries, they are more compact in design with much less weight and higher energy density.

Some more advanced electric motors for small sailboats (such as Spirit 1.0 Evo) feature an integrated lightweight battery. So you don’t need to worry about the complex wiring to hook it up or extra space to store the battery.

This is a huge plus if you want to use the electric sailboat motor on a tender or dinghy.

Here is also a chart that collects the weight of some popular electric sailboat motors for your reference:

For many people, another big problem with electric sailboat motors is the cost.

It’s true that a gasoline outboard with similar power is a lot cheaper to buy. However, the electric sailboat motor eventually wins in long-term operating cost. That’s especially the case if you are going to do a lot of motoring.

Electric sailboat motors save on fuel and maintenance costs, which can build up to a large amount over time.

Here is a chart that compares the cost of a 3HP electric sailboat motor (coming with a built-in battery) with its combustion counterpart:

That’s to say, you will cover the price difference for electric yacht motors eventually as long as you use it long enough. Click to check the details of the calculation .

What makes the electric sailboat motor even more worthwhile is it saves you a lot of hassles, especially for sailors who only use the engine in and out of the harbor. Dealing with the maintenance of the gas outboard for a 10 minute motor out of and into the harbor is disproportionate and painful.

*The higher horsepower electric sailboat motor may be different in terms of the cost calculation. Check out the outboard motor pricelist by HP for more information.

As you may have already noticed, electric propulsion has already been widely used in the marine industry:

It’s quiet while motoring, clean to handle, environmentally friendly, with less maintenance and operation costs.

The electric sailboat motors are easier to use with dramatically fewer moving parts to break and no worries about being a diesel mechanic to deal with the hard pulling start. You can have it always on, so it is ready whenever you need it.

And it makes even more sense in sailing applications:

You don’t really need to motor much if your plan is to actually sail. If you are completely becalmed, you will probably just need to motor at 2 knots to keep making way, which is easy for electric sailboat motors.

If you mostly use the motor to get into and out of the harbor, the electric sailboat motor also works great for you.

You can always charge up at the dock, motor out of the marina (or even motor to your sailing area or race start), then hoist the sails and when you’re through, the batteries are charged again.

The electric sailboat motor is also useful as a backup (kicker) motor in case your system goes down. That’s why you can see people pushing a lot of big boats with small electric motors. (Click to learn more information about kicker motors .)

Personally, it’s really nice to have an electric auxiliary in the boat – no smelly, messy diesel and motor oil to deal with, a much simpler system with less maintenance, and much, much quieter operation.

However, powerboats tend to have much higher requirements in terms of both power output and runtime. In that case, an electric sailboat motor can be hard to satisfy your needs.

How Do You Size an Electric Motor for a Sailboat?

As a rule of thumb, you will need approximately 1 HP per 550 lb of the displacement of your boat.

Generally speaking, a 3 HP electric sailboat motor can push a sailboat up to 25 ft and a 9.9 HP motor is sufficient for a 30 ft sailboat to motor at a satisfying speed.

However, bear in mind the horsepower you need always depends on your needs and applications.

It’s better to check the data from real-world tests to decide whether the electric sailboat motor is suitable for your specific needs.

For example, the 9.9 HP electric sailboat motor Navy 6.0 allows you to go at 6.9 mph (11.1 kph) on a 30 ft sailboat, and the range can be extended to 46.4 miles if you decrease your speed to 2.9 mph (4.6 kph).

Electric Sailboat Motor Conversion

Basically, there are two ways for you to convert your sailboat to a clean and quiet electric drive system:

You can either convert your current vessel to electric or buy an engineless yacht and install an electric sailboat motor on your own.

#1. Repower Your Sailboat with Electric Motor

If you decide to replace the diesel engine with an electric motor, you will need to do a lot of preparations:

The DIY approach requires an electric sailboat motor kit (including motor and controller), batteries, a good level of mechanical ability and basic electrical knowledge, as well as some common tools such as a voltmeter.

You will need to take the old engine out for the new electric sailboat motor installation. It’s not an easy task that involves removing the engine mounts and the drive shaft (dealing with the numerous hoses and cables), taking out the engine, exhaust system, fuel tank, and its attendant tubes, etc.

Remember to balance the boat to avoid listing during the electric sailboat motor conversion.

Then in with the new electric sailboat motor. The installation process can be straightforward if you choose the electric sailboat motor kit wisely (See steps below). Furthermore, you can set up solar charging for your electric sailboat motor with solar panels and charger.

Many sailors have recorded their electric sailboat motor conversion process and experience. Be sure to check them out to get some inspiration. For example, Ed Phillips has documented everything which can serve as a guide for newbies to get started.

Mind you there can be a whole heap that can go wrong in designing and maintaining the electric sailboat motor systems. You really need to be totally on top of it if you want decent performance or reliability.

If you are not that technically inclined, it’s better to talk to a specialist first to discuss your plan for a smooth electric sailboat motor conversion.

#2. Install an Electric Motor in a Sailboat

If you own an enginless sailboat, the electric sailboat motor conversion is much easier for you.

All you need to do is to find a reliable electric sailboat motor and install it in simple steps. The whole process can be easily done, even for beginners. Here we take the popular 6 HP electric sailboat motor Navy 3.0 as an example to show you the installation process:

• Step 1 : Rotate the clamps or use the screws to fix the outboard onto the sailboat.
• Step 2: Mount the steering system in the proper position.
• Step 3: Install the tiller on the electric sailboat motor.
• Step 4: Connect the batteries to the electric sailboat motor system.

Click to check the video tutorial that guides you through each step of the installation.

If you are worried about aesthetic issues and want higher horsepower options, an electric inboard motor can be a better suit for your sailboat. If you prefer an inboard motor for your sailboat, contact our OEM team to get an electric propulsion solution tailored to your needs.

Note : You might find some electric trolling motors rated by #s of thrust on the market. Actually, those electric trolling motors for sailboats can only provide limited speed and range. If you are heading into the wind, the trolling motors for sailboats are definitely not an ideal solution.

Once you’ve evaluated if electric sailboat motors are right for you, there are a lot of options for electric systems.

Here are some popular electric sailboat motors with positive reviews from customers worldwide. Fast charger is available for all the models recommended to reduce your charging stress.

#1. 3 HP Spirit 1.0 Evo

If you are looking for an electric motor for a small sailboat, be sure to check out the ePropulsion Spirit 1.0 Evo. It’s suitable for large daysailers or small cruising sailboats under 25 ft.

With the Spirit 1.0 Evo electric sailboat motor, you can go 5.5 mph (8.8 kph) at top speed on the 21 ft RS21 sailing boat, or troll for 20 hours continuously at 2.2 mph (3.5 kph) according to our test .

This electric sailboat motor with regeneration allows you to recover energy from the prop while under sail. It will start to generate power automatically when the sailing speed reaches 2 knots.

As an electric auxiliary sailboat motor, it can also be easily installed on your tender boats or yacht dinghies since it’s portable and easy to transport (with a lightweight integrated battery).

Features You Will Love:

• Come with the industry-first hydrogeneration capability
• Direct-drive technology makes it maintenance-free
• Portable with a 1276Wh large integrated lithium battery for long range
• Safety wristband keeps you safe in case of MOB

“Very happy with our Spirit Plus. Pushing our Kolibri 560 a 750 Kg sailboat, with ease. Doing about 5.8 km/h at 500W.” – Frank van Asten

#2. 6HP/9.9 HP Navy Evo Series

If you want a little more juice on the electric sailboat motor, check out the ePropulsion Navy Series. It offers 6 HP and 9.9 HP models for your selection and it provides sufficient power for sailboats up to 30 ft.

According to our test , the 6 HP electric motor Navy 3.0 can push the Catalina 25 sailboat (25 ft) at 6 mph (9.6 kph) top speed, while the Olga 33 sailboat (33 ft) can go at 7.5 mph (12 kph) with the 9.9 HP Navy 6.0 motor.

The Navy series electric sailboat motor also comes with regeneration features which can be recharged with hydrogeneration, wind turbine, and solar panel.

• Four controls to fit your sailboat installation and your boating style
• Accompany LiFePO4 batteries (need separate purchase) are more energy efficient
• Digital display offers real-time monitoring of the power and battery
• Magnetic kill switch and safety wristband keep you safe on the boat
• Electric start saves you trouble pulling the cord to start

Navy Series Electric Sailboat Motor Reviews:

“I have a Navy 3.0 with E80 on a Catalina 25 sailboat. It is working well. Currently I am using about 4% battery to go in/out of the marina by boat.” – Aaron Young

“Just finished my 8 weeks sailing journey in the Baltic Sea. The two Navy 3 outboards provide enough power for my 33ft catamaran. The 400W solar panels provided enough energy for engines and all other energy consumed on board with 2-6 persons. The two Navy Batteries provide power for engines and all other on-board electric devices. I never had to use shore power, so totally self-sufficient electric system.” – Martin Hildebrand

Information on using this Plugboats Guide

The top of this web page is the Illustrated Guide with photos of the motors and specifications to the right.

Sortable/Searchable Table

At the bottom of the page is a table that can be searched if you know you are looking for a certain type of motor (i.e. pod or saildrive), a certain power range, or for a specific weight/length of boat. If you are going to use the table, the page is best viewed on a computer rather than mobile or tablet.

Illustrated Guide

The motors are organized in alphabetical order by manufacturer, then by style of motor, i.e. fixed pod, steerable pod, saildrive and then by power of motor within those listing. For many styles there are multiple powers of motor available and where that is the case we have made it as easy as possible to line up the motor with its specifications. i.e. if there are three power of motor with different weights, it will be noted as kW: 2kw, 2kw, 3kw • Weight: 10kg, 12kg, 15kg. For some manufacturers the variations are more complicated and we have done our best to make it simple and understandable.

There is a lot of variety in the way manufacturers detail the technical attributes of their products. We have tried to take the most common measurements and assemble an ‘apples to apples’ comparison. See the notes below in ‘Measurements’

The photographs and drawings are from the manufacturers’ websites and are not shown in any consistent scale.

kW • Voltage • Current • HP: Not all manufacturers list all of these specifications. We have included the specifications available and where not available have used the notation N/A.

kW is the kW rating provided by the manufacturer. Most websites do not indicate whether it is input or output kW. When it is indicated, we took the output.

Voltage is most often referred on the sites as ‘Voltage’. Some indicate nominal or peak, we have used nominal and indicated if peak is also referenced.

Current Is noted when the manufacturer supplies the information. Generally it is measured in amperes: A. In some cases the manufacturer uses Amp Hours: Ah and we have noted it where that is used.

HP : is ‘HorsePower equivalent’ so that you can get an idea of the power of the motor in comparison to a HP rating you might be more familiar with. Where available, these measurements come from the manufacturer’s website, and different manufacturers measure the HP in different ways. Some even use metric horsepower, which is slightly different from imperial horsepower. Again, we have tried to make it as apples to apples as possible. (For general guidance, 1kW is round one and a third HP 1kW=1.3HP, or the reverse is that 1HP is around three quarters of a kW: 1 HP = .75kW).

Static Thrust. Torque, Efficiency: This is probably the specification that has the most variability. We have simply given whatever information the manufacturer has published on their website, when available.

Range and Running Time : We have not included estimates of range or running time because it depends on too many factors: battery size (sometimes type also), water conditions, speed, etc. The exceptions are for the ePropulsion and Torqeedo models which have batteries from the manufacturers specifically matched to the motors and therefore provide estimates on their websites.

General : If a manufacturer publishes a specification, we have tried to include it here, even tough other manufacturers may not include the same type of measurement.

»» Kräutler website

Kräutler is a long-established Austrian manufacturer of industrial electric motors. They began construction of electric boat motors in the 80’s mainly because they could not find a product that would live up to the standards of founder Oswald Kräutler. They make motors for industrial and ship use as well as recreational boats and probably offer the widest range of sailpods and saildrives on this page with everything from small .5kW steerable pods to electrically rotatable saildrives with power up to 30kW.

An explanation about the Kräutler section of this guide: The Kräutler fixed pods are available with AC motors (ACV) or DC motors (GPV). The AC are for smaller boats. They also come in two different configurations: fixed propeller and folding propeller. In the interests of making this page shorter, we have divided them in to the motor types for the written descriptions but have shown you the fixed and folding options in the images. In the table each of the motors has a separate listing. NOTE: The GPV motors are only suitable for short use in salt water.

Oceanvolt Servoprop Saildrive

The Oceanvolt ServoProp is a patented variable pitch sail drive that ‘combines a high efficiency sail drive with the most powerful hydro generator on the market’. Unique feature is the possibility to turn the propeller blades more than 180 degrees. The software controlled variable pitch sail drive adjusts the pitch of the propeller blades automatically so that the power generation and power output are optimal. The blades are designed to give the system maximum efficiency in forward, reverse and regeneration. With the blades set to the neutral sailing position, the propeller creates extremely low drag similar to the drag of a feathering propeller. ServoProp is capable of generating more than 1 kW at 7-8 knots & 3 kW at 11-12 knots.

Propulsion Systems for Multihull

Experience the pleasure of extended anchoring or overnighting without running a generator! The large propulsion battery bank (compared to standard house battery banks) enables much longer silent intervals; you can run all creature comforts (air conditioning, heating, refrigerator/freezer etc...) without the need to run a generator all night.

The Oceanvolt platform is designed and installed to become the complete power solution for the entire boat - including the 12V (or 24V) service power system as well as all other appliances/other comfort equipment (110/220V outlets). Range and recharging are achieved either through hydro generation or through a DC generator which can enable constant long-range cruising or bringing batteries up to a full charge in less than 2 hours.

Hydro generation is particularly suitable for catamarans as twin (or quad) motors means double (or quadruple) the energy. Catamarans also cruise more easily at faster speeds which means that regeneration capabilities are significantly higher (hydro generation capability increases significantly at speeds over 6kn).

Oceanvolt also offers repowering solutions for conversion of existing diesel engines – removing the diesel engine, fuel tanks and exhaust system - cleaning up greasy engine compartments and freeing up both weight and space below deck.

All Oceanvolt systems are engineered to operate at 48 volts for passenger safety and ease of repair. Oceanvolt systems are extremely low maintenance and do not require winterization (no annual engine maintenance costs).

Oceanvolt offers Hybrid or Electric systems in partnership with a wide range of multihull designers and boat builders. Multihull configurations are typically either twin systems or, in the case of larger cats, quad systems.

Buyers guide to electric boat motors (2023)

By Author Fiona McGlynn

Posted on Last updated: August 3, 2023

Considering making the switch to an electric boat motor? With electric vehicles now commonplace on the roads, it’s no wonder so many boaters are curious about electric boats.

While electric boat motors have been around for a while, in the last several years the technology has taken huge leaps, resulting in more powerful motors, longer-lasting batteries, and ultimately more options for recreational boat owners.

Today, many types of boats can be outfitted with an electric propulsion system including pontoon boats, sailboats, jon boats, powerboats, fishing boats, yachts, and trawlers . If your boat’s combustion engine is in the range of 1 to 135 hp (.75 to 100 kW), you should be able to find an electric substitute.

While electric boating hasn’t gone mainstream—it’s estimated that close to 2% of recreational boats are electric—it’s still a great time to be thinking about making the switch, particularly if you own a tender, sailboat, or boat on a green lake where combustion engines are prohibited.

Benefits and drawbacks of electric boat motors

Electric marine motors offer several advantages over internal combustion engines:

• They’re completely silent .
• No noxious fumes or smelly exhaust gases to deal with.
• Instant torque.  Electric propulsion provides instant torque, giving you better maneuverability and more consistent speeds in choppy conditions.
• Lightweight.  An electric setup (including motor, batteries, and generator) typically weighs less than its diesel counterpart.
• No fuel cost.  Charging an electric boat may cost a couple of dollars per charge.
• Easy to maintain.  Imagine the maintenance on an outboard with no gas, spark plugs, or oil! Electric motors are simple, more reliable, and virtually maintenance-free.
• Renewable power.  Once you’ve gone electric you can get power from renewable sources like wind generators and solar panels.
• Better for the planet.  Electric marine motors don’t produce water pollution or produce harmful emissions like carbon dioxide (CO2), nitrogen oxides (NOx), and hydrocarbon (HC).

• Range.  The greatest drawback of electric boats is their limited range, which is often measured in the 10s of miles. Range is limited because batteries don’t have the same energy density as fuel — they can’t provide the same energy, pound-for-pound as a tank of gas. A good battery monitoring system, one that displays the remaining range in real-time, can help boaters manage energy consumption and ease range anxiety. For those who want to go farther afield, hybrid propulsion may be a better option.
• Upfront cost.  This new technology isn’t cheap. For example, a small electric outboard boat motor may sell for two-and-a-half times the cost of a gas outboard. However, prices are expected to come down as the industry reaches scale.

Types of electric boat motors

Electric outboard boat motors.

Some of the first electric outboards to hit the recreational boating market were smaller electric motors, typically used as trolling motors on fishing boats.

Today,  it’s possible to buy far more powerful electric outboard motors in the 1 to 80 hp (.75 to 60 kW) range , with ever more powerful versions hitting the market each year. In 2022, Norwegian start-up, Evoy launched the world’s most powerful outboard to date, the 225kW Storm, a 300-hp beast of an electric outboard! 

The range on electric outboard boat motors varies dramatically depending on your boat, total weight, propellor, and battery capacity .

The range also depends on how fast you want to travel. If you go slowly you’ll have a much greater range.

For instance, at a slow speed (5 knots) Torqeedo’s Deep Blue 50R , a 50 kW motor (80 hp equivalent) with a 40 kWh battery, has a listed range of 33-100 nm. But at full throttle (20-25 knots), the listed range drops to 16-20 nm.

To get a better sense of what range to expect on your boat (at both low and high speeds), you can look at the manufacturer’s website. See our list of electric outboard brands below.

One of the great things about electric outboards is that they can use renewable power sources. So, for instance, you could plug your boat into a portable solar panel while picnicking and get an extra boost for the trip home.

Some electric outboard boat motors can even generate power! Motors with hydro regeneration capabilities can charge the batteries while the boat is being towed or under sail.

While hydro regeneration is a fairly new feature for electric outboards, some manufacturers, like EPropulsion, are offering it across their outboard product line.

Key features of electric outboard boat motors

Each electric outboard motor brand has slightly different standard offerings and add-on features. Here are some of the key features and options to look for.

• Waterproof.  Some electric outboards are fully sealed and designed to withstand immersion
• Remote controls. Choose between tiller and remote throttle controls
• On-board computers . Some electric outboards come with chartplotter connectivity, navigation functions, sonar, GPS anchoring, and autopilot features
• Built-in or stand-alone batteries.  Some of the smaller motors come with built-in batteries, while the larger ones have separate battery packs
• Battery monitoring and tracking systems  that calculate and display the remaining range in real-time
• Shaft length.  Electric outboards come in both short and long shaft lengths to accommodate a variety of applications.
• Hydro regeneration capabilities 

Electric outboard manufacturers

These electric outboard boat motor manufacturers (listed in alphabetical order) range from small startups to large companies and serve the North American market.

If you’re looking to learn more about what each of these companies offers (and how they compare) I’d highly recommend checking out the  Plugboats’ electric outboard guides and directories . Jeff Butler, the editor at Plugboats has done a great job of compiling motor specifications from across the market.

Headquartered in San Diego, California,  Bixby  makes a small electric motor system for kayaks, inflatable boats, canoes, and paddleboards.

Elco  has been building electric motors for 125 years and counts the likes of Henry Ford and Thomas Edison among their customers. Their award-winning electric marine motors range from 5 to 50 hp. The company is based in Lake George, New York, and its electric motors can be found on boats around the world.

Flux Marine

Flux Marine was founded by mechanical engineering Princeton grads and offers three outboard models—a 40 hp, 70 hp, and 100 hp. In 2021, they won an award for the best new green product at the Newport International Boat Show.

Joe Grez, a consumer product developer from Washington, invented the  EP Carry , a compact, ultralight electric outboard system because he was concerned about exposing his young daughter to the carbon monoxide (CO) emissions produced by gas outboards.

The EP Carry retails for $1,600 and is a great size for small vessels like dinghies, canoes, inflatable boats, and kayaks.

ePropulsion

ePropulsion , based in Guangdong, China, manufactures 3 to 9.9-hp electric motors for sailboats, fishing boats, as well as dinghies and tenders. They all come with hydro regeneration capabilities.

Mercury Marine launched the Avator 7.5 electric outboard (3.5 hp equivalent) in early 2023. The leading outboard manufacturer is currently developing more powerful 20e and 35e models which it plans to release later this year.

In 2023, Newport , a well-known US-based inflatable boat manufacturer, launched three small outboards ranging from 1.8 to 3 hp.

If you’re into fishing, you’re probably familiar with the Minn Kota  name, derived from MINNesota North DaKOTA, prime fishing country where the company has its roots. They introduced their first electric trolling motor back in 1934 and they’ve been making them ever since.

Stealth Electric Outboards

The 50 and 75-hp  Stealth electric outboards  were developed by Scott Masterston of Houston, Texas.

German manufacturer,  Torqeedo , has been leading the propulsion industry for years and sells some of the best e outboard motors in the 1 to 80-hp range

Vision Marine Technologies  (formerly The Canadian Electric Boat Company). 

Based in Quebec, Canada,  Vision Marine Technologies  has been in the boating industry for 25 years and produced some very innovative electric boats. In 2021, they launched E-Motion 180E, one of the most powerful electric outboards on the market.

Electric inboard boat motors

Today’s electric inboard motors can provide anywhere from  3- to a whopping 330 hp (2 to 246 kW)  and are used in a range of applications from heavy displacement vessels to fast, planing powerboats.

Similar to outboards, the range on electric inboard engines will vary based on your boat, load, battery capacity, and boat speed (among other things).

However, with an inboard electric boat motor, you have the option of a hybrid motor which can significantly extend your range. We’ll discuss the pros and cons of hybrid boat motors later in this post.

Sailors may also want to consider choosing an inboard electric motor with hydro regeneration capabilities. These electric power motors can charge the battery while the boat is under sail.

DIY electric inboard boat motor conversion

One way to save money on an electric inboard is to do the installation yourself. There are a few DIY electric inboard boat motor conversion kits available on the market.

I’ve spoken with a few sailors who’ve had great success replacing their inboard diesel engines with these electric boat motor conversion kits from  Thunderstruck-EV , an electric drive manufacturer in Santa Rosa, California.

Key features of electric inboard boat motors

Each brand has a slightly different set of electric inboard motor options. Here are some of the key features and options to look for.

• DIY conversion kits
• On-board computers  and touchscreen display
• Waterproof  system components

Electric inboard manufacturers

US manufacturer, Elco Motor Yachts , has been building electric motors for over 125 years, having gotten their start in 1893, supplying electric boats for the Chicago World’s Fair. They have seven inboards ranging from 6 to 200 hp.

Electric Yacht

Electric Yacht  is a US supplier focused on providing plug-and-play electric motors for DIY installations on sailboats. Their electric propulsion systems range from 10 to 30. They’ve had over 450 installs in 10 years of production.

Oceanvolt  is a leader in regenerative systems and their electric inboard motors are popular among sailors. They offer shaft drive systems ranging from 6 to 60 hp.

Torqeedo, a German manufacturer, is the world’s leader in electric boat motors. They have two lines of inboards, one for displacement boats and another for fast planing boats. Their Deep Blue inboard systems range from 25 kW to 100 kW (40 to 135 hp)

Hybrid systems

Hybrid systems combine an electric motor and combustion engine, so you can cruise in silence (but know you’ve got enough gas to get home). These systems offer  many of the benefits of pure electric motors, without the limited range. 

If you want  additional power for onboard luxuries  like air-conditioning, hybrids can also provide a significant increase in house-side fuel efficiency.

The downside to any hybrid solution is that the systems are far more complex . Not only do they require more equipment, but, for an optimized system, you’ll need highly sophisticated software to manage multiple power sources and switch back and forth between diesel and electric.

Unsurprisingly, the increased complexity adds cost, making hybrids less economical than either a conventional or pure electric install.

Serial vs. parallel hybrids

As with cars, there are  two types of hybrid systems: serial and parallel.  A serial hybrid uses a generator to power a large electric motor connected to the drive shaft. Whereas, a parallel hybrid has both a conventional combustion engine and a small electric motor connected to the drive shaft.

There are plenty of factors to consider when choosing between a parallel and serial system. Marine mechanics and electrical expert, Nigel Calder, does a great job of explaining  serial and parallel hybrids  in detail.

In general, serial systems may be a better fit for boats that can get most of their propulsion energy from renewable sources (e.g., a sailing catamaran). Whereas, a parallel system makes more sense on boats that regularly require sustained propulsion (e.g.,  Greenline’s power yachts ).

Key features of marine hybrids

• Parallel and serial hybrid options
• Integrated energy management  systems

Marine hybrid manufacturers

Elco motor yachts.

Elco  manufactures serial, parallel, as well as a combined serial-parallel system. Their systems can be used on sailboats, trawlers, yachts, and boats up to 85′ feet.

Hybrid Marine Ltd.

Hybrid Marine  sells parallel hybrid systems in the 10 to 230 hp range. Beta, John Deere, and Yanmar’s hybrids all incorporate Hybrid Marine technology.

Finnish manufacturer,  Oceanvolt , offers serial hybrid systems for both sailboats and powerboats.

Torqeedo  makes hybrid systems for yachts up to 120 feet as well as powerful motorboats.

Electric pod drive and sail drive

Several manufacturers are now making electric pod and sail drives. These electric drive systems are more efficient and can save space onboard.

Electric pod and sail drive manufacturers

Electric Yacht  produces a range of sail drives that can replace diesel engines up to 75 hp.

propulsion  sells a 3 hp, 6 hp, and 9.9 hp fixed pod drive.

Oceanvolt’s  sail drives range from 6 kW to 15 kW (8 to 20 hp)

Torqeedo  sells a 40 hp and 80 hp equivalent electric sail drive as well as electric pod drives in the 6 to 25 hp range.

While it’s possible to power an electric motor with a conventional lead-acid battery, there are many  good reasons to upgrade to lithium-ion batteries.

Their increased usable  capacity is roughly double  what you can get out similarly sized lead-acid battery. More battery capacity means more range—and hours of fun—on your electric boat.

They also  charge more quickly  and have a  longer life span  than lead-acid batteries. Unlike flooded lead-acid batteries, which need to be watered, lithium-ion batteries are practically maintenance-free.

The downside is that lithium-ion batteries are far  more temperature-sensitive  and can’t be charged much above 113 F (45 C) or below 32 F (0 C).

They  can also present major safety issues . Lithium-ion batteries can go into what’s known as thermal runaway—a self-heating process that can cause the battery to catch fire.

Simply put,  lithium-ion batteries are NOT a drop-in substitute for lead-acid batteries.  They need to be specially designed for the marine environment and paired with a robust battery management system.

Electric motor manufacturers often provide complete solutions (including motor, batteries, and battery management system). It’s a good idea to work with a manufacturer with extensive marine experience and an ABYC-certified technician on any installation.

The other catch is that lithium-ion batteries  cost two to four times   as much as lead-acid  batteries. However, the increased capacity and longer life span may make lithium batteries a better value option over the long run.
