These very powerful bow thrusters are supplied fully mounted with a type 400/7.2V electric motor. The propulsion is provided by a flat propeller (paddle) sucking in water on one side and expelling it through the jet nozzles at high pressure on the other. This design is very robust and very stable and maintenance required is very little to none. The pump housing and the extension tubes are made of ABS. The motor is sealed with a G-ring and an O-ring thereby ensuring a good seal so that the thruster 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.
