ABSTRACT:
This invention provides a marine propulsion device comprising a propulsion unit, a transom bracket adapted to be fixedly connected to a boat transom and a swivel bracket mounted on the transom bracket for pivotal movement about an axis which is horizontal when the transom bracket is boat mounted. The marine propulsion device also includes a king pin assembly mounted on the swivel bracket for pivotal steering movement of the propulsion unit and a mounting mechanism for mounting the propulsion unit on the king pin assembly and permitting limited rotational movement of the propulsion unit relative to the king pin assembly. The marine propulsion device also includes a trim tab mounted on the propulsion unit for pivotal movement about an axis transverse to the horizontal axis, and a linkage mechanism for displacing the trim tab about the transverse axis in response to rotational movement of the propulsion unit relative to the king pin assembly.
