Product details

Sail into the future and experience the magic of an electric boat drive - efficient and sustainable.

No noise, no smell, no exhaust, just plenty of power, range and freedom. An electric boat drive will transform how you sail and live on the water for a totally new boating experience. Motorising your boat is a piece of cake and can be done quickly and safely with perfectly matched components. From motors to displays, battery packs to throttle controls, you're sure to find the perfect all-in-one solution for your needs.

The allure and advantages
There'll be no going back once you've tried an electric boat drive. Sustainability, performance and flexibility combine to create a uniquely fascinating experience that most boat owners can't resist.
No vibrations, no smell, no dirt. An electric boat engine takes clean mobility on the water to a new level. At the same time, they're also efficient, powerful, and easy to maintain, not to mention inexpensive to operate. But not only do they give boaters a clear conscious and unique driving experience, there are also many practical advantages that will bring a smile to your face on every trip.
Total tranquillity
Electric motors with no gearbox are virtually noise-free.

100% emission free

Move around in nature with no exhaust fumes or smells. Electric motors also leave no oil in the water as they don't require lubricating.

Low maintenance and cheaper in the long run
Electric motors are long-lasting and have no wearing parts. They therefore require little servicing and are cheaper to run than combustion engines. Unexpected breakdowns and repairs are a thing of the past.

Safe and easy handling
State-of-the-art lithium batteries are waterproof, chemically stable and have optimum protection against short circuits and fire. Drives with a voltage of 48 V are particularly easy to install because they are safe to touch.

High and flexible range
With the right battery pack, the drive system can be precisely tailored to your individual needs and area of application. So you can easily be on the go all day and fully charge overnight.

Combustion engines not welcome
With more regions banning the use of combustion motors, including Germany, some areas are only accessible by electric drive. Don't let any ban affect you and plan for the future with an e-motor.


Choosing the right WaterWorld electric inboard
To help you find the right motor, some questions must first be answered. What is the size and weight of your boat? Where do you usually sail? How many kilometers do you wish to cover every day? What kind of speeds do you sail at? Whatever your answers, you're sure to find the right motor.
