»» Guide to Electric Outboards Under 5kW

Welcome to what we believe is the most complete guide to electric outboard boat motors with power more than 5kW. It has been assembled to provide a single place where someone interested in electric outboards and electric boats in general can find comparative information for motors made all over the world: Europe, USA and Asia.

Specifications

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.

General Organization

The motors are organized in alphabetical order by manufacturer and then by power of motor within that manufacturer’s listing. In the interests of user friendliness, we have bunched the short (S) and long shaft (L) models together, and for some manufacturers have also bunched the range of motors, mainly because that is how those manufacturers display them on their websites.

The blue links will connect you to the manufacturer’s entire website, the page for the motor/s being detailed, and in some cases, a link to download a brochure. At the bottom of the page is a sortable and searchable table of all the information. While the page can be viewed on a mobile device, there is a lot of information. We encourage you to view on a desk or laptop browser for maximum legibility and flexibility.

We welcome any input you may have to make this guide better – a different grouping, perhaps we have left out a motor or are unaware of a manufacturer. If you do have a suggestion, correction or improvement, use the Contact Form at the bottom of the page.


Measurements

kW • Voltage • HP:
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 larger of the two, usually the input kW
Voltage is most often referred on the sites as ‘Voltage’. Some indicate nominal or peak, and some use the term ‘vdc’. In those cases we have used the nominal rating and indicated it as such.

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).
Some manufacturers do not use HP as a measurement but instead provide specifications for torque, thrust and RPMs. In those cases, and where possible, we have used standard conversion formulas to obtain a HP rating.

A word about Static Thrust: Some boat owners are familiar with the term “Static Thrust’ as a yardstick for measuring fossil fuel engines. Very few electric boat manufacturers use this term or supply this information, so in the interests of ‘apples to apples’ comparisons, we have not included it.

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 e-Propulsion and Torqeedo models which have batteries from the manufacturers specifically matched to the motors and therefore provide estimates on their websites.

Weight and Length: are in metric. 1 kilogram = 2.2 pounds, ( a 15kg motor = 33 lb), 1 centimetre = 2.54 inch (63 cm shaft = 25″)

Price: These prices are intended as a guide, to give an idea of comparative pricing, not as quotes for the products. The information was taken from a variety of sources. If the manufacturer has a suggested list price, it is noted. Otherwise, information came from dealer websites. In some cases we could not find a dealer price and we have contacted the manufacturer for a MSRP. These will be added as they arrive. PRICES ARE FOR MOTORS ALONE and do not include batteries (even for e-Propulsion and Torqeedo). All prices are in $US because everyone is familiar enough with it to convert price to their own currency.

Aquamot

Aquamot was founded in 2003 by Ing. Siegmund Hammerstrom and has grown to be a leading manufacturer of electric motors. They have outboard and pod motors from 1.1 kW to 25kW. Covered below are the 11kW to 25kW motors.
Measurement: Aquamot uses a power measurement of “comp. thrust comb engine. (PS)” Which we are taking to mean “comparable thrust to a combustion engine (PS)” PS is the German abbreviation for a metric horsepower: PferdeStärke and we have used this for the HP figure.

Bellmarine

Bellmarine has a history going back to 1999 and involves a motor manufacturer merging with a battery accessory manufacturer and then being purchased by Transfluid, a large scale industrial motor manufacturer. Perhaps for this reason, it is a very modular system and difficult to compare with other outboard motors and almost impossible to price compare. This is compounded because the Bellmairne outboard is essentially a saildrive system bolted on to the back of a boat. Having said that, these are the specifications on the Bellmarine website.
Measurement: Bellmarine does not provide any HP or thrust information, but focusses on RPMs and propeller size. HP cannot be calculated without torque specifications, which are not available on the Bellmarine website or in brochures.

Elco

Elco (Elco Motor Yachts) is the oldest electric boat motor company in the world, having been started in 1893 as the the Electric Launch Company to supply electric boats for the Chicago World’s Fair. It went on to become the USA’s second largest boat manufacturer. In 2013 the company decided to focus exclusively on electric motors – outboards, inboards and hybrids. The company also offers two outboards under 5kW.

Huracan

Huracan was founded at the beginning of 2012 in Venice. Since then its goal has been to build entirely electric marine motors, non polluting, highly performative and more reliable than those already on the market. The outboard motors come in two models: Speed and Light. The Light version, as seen in the photos, is shorter, and also comes with two options regarding attachment to the transom. A regular tilt version and, the vertical lift version, shown in the Light photo below, in which the the motor slides up and down vertically while keeping its angle unchanged with respect to the transom.

Krautler

Krautler is a long-established German manufacturer of industrial electric motors. They began construction of electric boat motors started in the 80’s mainly because they could not find a product that would live up to the standards of founder Oswald Kräutler. They continue to make electric motors for industrial and ship use and have a wide range of motors for smaller recreational power and sailboats.

LGM

LGM stands for Leo Greentier Marine, a division of Leo Motors, a Korean company responsible for that country’s first high-speed electric vehicle. It is difficult to compare the LGM outboards to the others on this list using information available from their website because the company appears to measure performance using different criteria.

One of the innovations of LGM is that they have a patent for a modular battery system called Cartridge Battery Systems (CBS) that divides battery power packs into 15 to 30 pound cartridge units. This may be part of why their measurements do not line up with other specifications.

We have reached out to the company to understand how their measurements relate to those of other manufacturers, in the meantime we are publishing the information as it appears on their website

Stealth Electric Outboards

The Stealth E40 was developed by Scott Masterson of Houston with the underlying concept of having parts for an electric motor as easily available as those of a gas outboard. The lower unit, shaft and body come from a competitor of Yamaha outboards and an electric motor and controller is installed in place of the ICE powerhead, fitting under the cowling and enabling the outboard to be installed and operated in the same way as a fossil fuel motor but without the fumes, noise and maintenance.
