Bow and Stern Thrusters

Keypower thrusters have been trusted by vessel operators who face the harshest marine environments on a daily basis. As a result of Keypowers’ underlying drive to meet the heavy demands of commercial use, their bow and stern thrusters have quickly become the trusted solution in a variety of marine markets that include military applications as well as the pleasure and yacht markets where owners have grown to appreciate reliable products that withstand the test of time.

Both electric thruster and hydraulic thruster models are available, ranging from 5hp (8” / 20.3cm) to 400hp (40” / 101.6cm). Based on hydrodynamic fundamentals, the streamlined shape of the housing coupled with the auger style propeller provides maximum thrust per horsepower while maintaining equal thrust in both directions. Integrated hydraulic packages are available in proportional control or On/Off.

Keypower thrusters use duplex stainless steel for the main shaft due to its unique combination of properties: high strength, excellent corrosion resistance and superior resistance to galling and seizing. The gear housing contains a matched set of spiral bevel gears that are custom designed to ensure reliability and silent operation. A large, replaceable, sacrificial zinc is used to protect the thrusters from electrolysis. High quality materials, robust engineering and a commitment to customer service make Keypower bow and stern thrusters the safe decision for any application.
