Keypower Thrusters are increasingly becoming
standard equipment on today's pleasure and
commercial craft, and for good reason. If you
have ever struggled with high winds and strong
currents, or experienced the frustration on trying to
maneuver into a tight slip, the additional leverage
provided by a Keypower thruster is like having
an extra hand onboard.

Keypower thrusters are of rugged design and built to withstand
the most severe commercial applications.

Keypower thruster systems offer

  • Low maintenance
  • Easy installation
  • Guaranteed reliability
  • High thruster-to-horsepower ratio

The airfoil contoured torpedo shape minimizes resistance to flow and cavitation.  This combined with the auger propeller provides high efficiency with equal thrust in both directions.  The gear housing contains a matched set of spiral bevel gears custom designed to Keypower specifications for maximum reliability and silent operation.

Duplex stainless steel has been selected for the main shaft because of its unique combination of properties:  high strength, excellent corrosion resistance and superior resistance to galling and seizing.  And to protect your Keypower thruster from electrolysis, a large replaceable sacrificial zinc is used.

Keypower Thrusters combine the highest quality materials and engineering to provide you with years of safer and easier handling.

Keypower Thruster package includes:

  • Bow thruster with propeller and drive motor
  • Switch box or solenoids mounted on motor (8")
  • Main station on/off control with joystick
  • Installation instructions
