This powerful bow thruster is supplied fully mounted with a Power 400 7.2-Volt electrical motor. The propulsion is provided by a flat propeller (pedal) which pressurizes the water through the tube whereby the entire assembly functions as a pump. This design is very robust and very stable and requires 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 so the bow thruster can be installed vertically or horizontally. The motor with the pump housing cover can be removed easily.
This size is applicable for 12-24" ships with an approximate weight of 3-8 pounds.
