ABSTRACT:
Disclosed herein is an outboard motor comprising a transom bracket adapted to be connected to a boat transom, a propulsion unit which is mounted to the transom bracket for pivotal steering movement of the propulsion unit in a horizontal plane and for pivotal movement of the propulsion unit in a vertical plane between a lowermost running position and a full tilt position, which propulsion unit mounting includes a first pivot connecting an intermediate bracket to the transom bracket for pivotal movement of the intermediate bracket relative to the transom bracket about a first pivot axis which is horizontal when the transom bracket is boat mounted, whereby to enable movement of the propulsion unit through a tilt range, a second pivot connecting a swivel bracket to the intermediate bracket for pivotal movement of the swivel bracket with the intermediate bracket and relative to the intermediate bracket about a second pivot axis parallel to the first pivot axis, whereby to enable movement of the propulsion unit through a trim range, and a king pin pivotally connecting the propulsion unit to the swivel bracket for steering movement of the propulsion unit relative to the swivel bracket about a generally vertical axis and for common pivotal movement with the swivel bracket in a vertical plane about the first and second horizontal axes, hydraulic cylinders for sequentially displacing the propulsion unit from the lowermost position through the trim range and then through the tilt range to the full tilt position, and a support on the transom bracket for providing side support to the intermediate bracket.
