  • Description
  • Comparison Chart
  • Installation
  • The ST350 Stern Thruster is perfect for monohull style boats up to 60' in length, and for houseboats up to 70' in length; the unit mounts to the underside of a horizontal surface like a swim platform, or to a vertical surface such as a transom. No tunnel or motor inside the hull is required. All mounting holes are above the waterline. Mounting to a vertical surface like a transom can easily be done with the optional stern mounting bracket. Offering an immediate response with its powerful water cooled 24V motor, the heavy-duty 8" aluminum propellers quickly pull the boat quietly and smoothly. Saltwater proven, the rugged aluminum and stainless steel thruster is anode protected to prevent corrosion. It is finished with anti-fouling paint over epoxy primer.

    Our thrusters mount easily using our unique, universal mounting system. Virtually any V-shaped bow, pontoon or stern can be accommodated.

    And, to make things even simpler, our thruster systems now come standard with our wireless joystick technology. The included wireless joystick control offers simple plug and play for the helm-to-motor controller connection, eliminating the hassle of long wire-runs, and shaving hours off installation time.

And we’re always available to provide phone support if any questions come up.

Our thrusters have been specifically designed for easy installation by any marine mechanic, and as always, we’re available to speak with your installer if there are any questions.
