Bow Thrusters 108-01 to 108-05

These very powerful bow thrusters are supplied fully mounted with a Power 400 7.2-Volt electrical motor. The propulsion is provided by a flat propeller (pedal) which pressurises the water through jet nozzles whereby the entire assembly functions as a pump. This design is very robust and very stable and requires the very little maintenance. The pump housing and the extension tubes are made of ABS (acrylonitrile butadiene styrene). The motor is sealed with a G-ring and an O-ring which prevents the entry of water whereby the bow thrusters can be installed vertically as well as horizontally. The motor with the pump housing cover can be removed easily. The cover has an O-ring that ensures water-tight sealing of the entire assembly. For further technical information:

See the dimensional drawing and the technical details of the motor.
