10 kW electric outboard motor

Easy to handle

Mount your Momentum OBM in seconds and easily adjust the trim with our single-lever control. This is the easiest OBM in its class to install and remove. Leave it on the boat, store it below deck, or take it home.
Security
A fully integrated CAN-bus interface between the OBM, battery, and throttle ensures safe and seamless operation. A magnetic emergency stop switch, custom IP67-rated waterproof connectors, and battery provide you with security even in the toughest conditions.
Integrated screen

A high-contrast display with integrated GPS with range & speedometer. User-friendly around the clock – even in bright sunlight.
Unmatched power
Almost twice the power of competitors in the same weight class and instant torque for lightning-fast acceleration.
Lightweight design
Compact and easy to handle, with a quick-release for simple assembly and disassembly, all in a corrosion-resistant construction that withstands the toughest marine conditions.
Passive water cooling
No water pump that can break down or water channels that need to be flushed – which eliminates yet another major maintenance issue.

MB-6, a 72V powerhouse

The MB-6 battery fits in a standard fuel compartment and delivers power that lasts a long time. The impact-resistant casing and CNC-machined aluminum handle provide robust handling and are waterproof. The proprietary Battery Management System (BMS) has all built-in safety features to ensure the safety and longevity of the battery cells. The BMS also communicates with the OBM to ensure that full power is only delivered when the dead man's grip is activated – to protect both the user and the battery.

FAQ about M10
How long is the range of an M10?
The range varies depending on the type of boat, weight, and speed. For example, a Highfield Classic 310 with one person on board can travel up to 12 nautical miles at full throttle. At lower speeds, the range increases significantly and can potentially reach over 150 nautical miles per charge.
How do you handle range anxiety if you have an M10?

Our engines have built-in GPS that calculates and displays your remaining range in real-time based on speed and load. This helps you plan trips safely. Slowing down significantly extends the range, and after a few trips, the range becomes very predictable.
How is the shaft length of M10/M6 and U2 determined?

M10/M6 uses the same dimensions as traditional combustion engines. If your boat requires a 52 cm shaft for a standard outboard motor, choose the same shaft length for M10/M6.

U2 is a bit different; the engine power means that a cavitation plate cannot do a proper job. This, in turn, causes electric motors with this capacity to easily cavitate if they do not run deep enough. If you are a bit on the edge between long/short shaft, choose the longer one.
