ABSTRACT:
A system for utilizing a power assit for rotating a boat motor about a vertical axis near the stern of the boat. The power assist is provided by a small rudder mounted along the center line of the motor and positioned in a vertical plane through the axis of the propeller and aft of the propeller in the slip stream. Means are provided to operate the small rudder by the apparatus that controls the rotation of the motor, the rotation of the rudder being effected prior to applying torque to rotate the motor assembly. In operating the turning control for rotating the motor assembly, there is a slack condition whereby the first movement of the control rotates the small rudder into a position whereby the moving slip stream from the propeller exerts a torque tending to rotate the motor assembly in the desired direction. If the torque is insufficient to rotate the motor, movement of the control in a continuing direction applies a torque to directly rotate the motor assembly.
