Electric Outboards: More than 5kW

Plugboats Guides Motors News Motors For Sale

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.

General Organization

The top of this web page is an Illustrated Guide with photos of the motors and specifications to the right. At the bottom of the page is a Sortable/Searchable Table that lets you compare motors easily. If you are going to be using the table extensively the page is best viewed on a computer rather than smartphone or tablet.

  • Illustrated Guide

The motors are organized in alphabetical order by manufacturer, 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. For the specifications we have tried to make it a user friendly as possible. If there are 3 models in the line, we will give the specs for each model with a comma in between. If there are many models, we give a range without lining the specs up with specific models.

  • Sortable/Searchable Table

The table can be searched with any keyword – manufacturer, for instance, or can be sorted by any of the columns: Power, Motor Type, Shaft Length, Other Miscellaneous information, Country of Manufacture and Price.

Source of Specifications

All specifications are taken from the manufacturers’ websites or brochures without any independent verification. There is a lot of variety in the way manufacturers detail the attributes of their products, particularly when it comes to ‘Power’. Some use peak power as the measurement, some use continuous power, and there are other variations. Some quote minimum RPMs for their motors, others quote maximum RPMs. There is also no set standard for ‘horsepower equivalent’. We have tried to present the information as close as possible to an ‘apples to apples’ comparison.

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

Measurements
All measurements are in metric. We have not given comparisons to Imperial/US measures except in ‘horsepower equivalent’, which is in itself not standardized due to how the power is measured by each manufacturer.

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. 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. 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, or the reverse is that 1HP is around three quarters of a kW



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″)



Running Times These obviously depend on a variety of conditions. We have used the information from the manufacturer’s website, taking the range/time at the lowest speed and highest. Some manufacturers also include range in their analysis of the capabilities of a battery and motor combination, but since not all provide that, we have used only running times.

Motor Types 
There are advantages and disadvantages to each kind of electric motor. Some manufacturers use abbreviations to describe their motors, others use the full words. We have used whatever the manufacturer prefers, but when abbreviations are used, this is what they mean:

  • BLDC: BrushLess Direct Current
  • PMAC: Permanent Magnet Alternating Current
  • PMSM: Permanent Magnet Synchronous Motor

Battery Glossary

  • AGM: Absorbent Glass Mat (lead acid)
  • VRLA: Valve Regulated Sealed Lead Acid
  • Li-ion: Lithium Ion
  • LiPo: Lithium ion polymer
  • LiFePo, LiFePo4: Lithium-iron-phosphate
Prices
These prices are intended as a guide, to give an idea of comparative pricing, not as quotes for the products. The range of prices reflects the options for the model (i.e. from short shaft tiller steer to long shaft remote steer).

We have included prices only when listed on the manufacturer’s website. Many manufacturers will have pages on their sites with dealer locations and links to dealer websites where pricing can be found.

While prices between dealers are fairly consistent, there can be big price swings between continents. The $ amounts are US$ unless otherwise noted. Finally, if the battery is integrated, it is in the price, if the battery is separate, the listed price is for the motor only.

      Great info. Thanks. The cost of an electric motor compared to a standard petrol is crazy money. Can’t justify the massive cost to go electric yet.

    You have the most informative website I’ve ever seen, factual, direct and well explained.
    Unfortunately all of the motors shown are out of my price range, (I have rolls Royce expectations and mini cash), that said, if I ever win the lottery I would put great faith in your website. Thankyou for your explanation and obvious amounts of time given and wish you well for the future, regards Rob (England)

    Very nice to have all of this information here!

    I’m having a hard time finding comprehensive surveys of reliability. I think it would be phenomenally useful to allow me to easily see and sort by how reliable the manufacturer _thinks_ their motor is: sort by warranty length.

    Thanks!

    Looks like in the area of 30-45KW we don’t have a big choice in Europe – overpriced Torqeedo or Aquawatt. Would be glad to see bigger competition.

    Excellent. This is also a great guide to determine a potentially much less expensive DIY approach. Used outboard motors may be converted, with a bit of patience. As for the ICE cost comparison: happy hour cruises are very peaceful with electric.

    Reviewing from Australia this information has been highly informative and has abled me to enquire more specifically to manufacturers around the world. Much gratitude for the compilation of information.
