ABSTRACT:
Disclosed herein is a marine propulsion device comprising a transom bracket adapted to be connected to a boat transom, a stern bracket having an upper end, a first pivot connecting the upper end of the 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 swivel bracket, a second pivot connecting the swivel bracket to the stern bracket below the first pivot for pivotal movement of the swivel bracket relative to the stern bracket about a second pivot axis parallel to the first pivot axis, a propulsion unit including, at the lower end thereof, a rotatably mounted propeller, a third pivot 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, and a system for sequentially pivotally displacing the swivel bracket and connected propulsion unit about the second pivot axis and then about the first pivot axis.
