Disclosed herein is a marine propulsion device comprising a transom bracket adapted to be connected to a boat transom, a first pivot connecting a stern bracket to the transom bracket for pivotal movement of the stern bracket relative to the transom bracket about a first pivot axis which is horizontal when the transom bracket is boat mounted, a second pivot connecting a swivel bracket to the stern bracket below the first pivot for pivotal movement of the swivel bracket with the stern bracket and relative to the stern bracket about a second pivot axis parallel to the first pivot axis, a king pin pivotally connecting a propulsion unit including a rotatably mounted propeller 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, a trim cylinder-piston assembly pivotally connected to the stern bracket and to the swivel bracket, a tilt cylinder-piston assembly pivotally connected to the transom bracket and to the stern bracket, and a fluid conduit system communicating between a source of pressure fluid and each of the tilt cylinder-piston assembly and the trim cylinder-piston assembly and including apparatus operable, during reverse operation of the propulsion unit, for causing initial full extension to the trim cylinder-piston assembly, followed by extension of the tilt cylinder-piston assembly, and for causing initial full contraction of the tilt cylinder-piston assembly, followed by subsequent contraction of the trim cylinder-piston assembly. |
