Overview

The ST230 Stern Thruster from Sideshift is perfect for most boats up to 30' in length; the unit attaches to the cavitation plate of any outboard motor or sterndrive, eliminating the installation issues common to most outboard or sterndrive powered boats. The unique mounting position creates zero drag as the thruster rides above water when the boat is on plane, and the unit can be easily installed in-water in only a few hours. 

The powerful, water-cooled 12V motor and heavy-duty 8" aluminum propeller provides instant lateral thrust for stress-free docking in any situation. Saltwater proven, the thruster is anode protected and finished in acrylic enamel paint over epoxy primer to prevent corrosion.

And for boats with existing bow thrusters, you can add our dual wireless joystick option for easy single-handed operation of both thrusters, providing true 360 degree control in any docking situation.

  • Thruster

  • Wireless joystick(Dual joystick when purchasing bow and stern thruster kits together)
  • Wiring harness and mounting hardware
