  • Precise control with drive-by-wire throttle and steering
  • Ultra-low maintenance

Intuitive. Connected. Sustainable. Safe.

RAD 40 highlights

Compact design

Smaller than its conventional equivalent, the RAD 40 remains behind the transom when tilted up. Designed so that the motor doesn’t intrude into the vessel’s deck space.

Advanced 180° steering

Fully integrated, 180 degree drive-by-wire electric steering for easy docking in even the most testing conditions.

Closed circuit cooling

With no intakes to clog or risk of broken impellers, the RAD 40 cooling system requires no maintenance.

60 hp equivalent

40 kW of electric power providing equivalent thrust to a 60 hp petrol outboard. The high torque axial flux motor is perfectly paired with bespoke propellers to deliver exceptional acceleration.

Fast charging

The 400 Volt architecture is fully compatible with the growing network of fast chargers. RAD can provide battery systems from 20 to 240 kWh or work with you to integrate your choice of battery.


Precise throttle

The highly responsive fully digital RAD throttle provides control in every situation. It features a neutral safety mechanism and illuminated tilt and trim buttons.

RADBus control system included

Complete drive-by-wire control system and cables for easy installation.

Smart steering

To compliment the 180° steering on the RAD 40, a smart steering wheel is used with variable resistance and adaptive mapping – limiting the steering angle at high speeds.
