Abstract
Disclosed herein is a marine propulsion device comprising a bracket adapted to be fixed to a boat transom and having an upper portion and a lower portion, a propulsion leg including a rotatably mounted propeller, a first ball joint universally connecting the propulsion leg and the lower bracket portion, a hydraulic cylinder-piston assembly having first and second ends, a pivot connecting the first end of the hydraulic cylinder-piston assembly to the propulsion leg about an axis which is generally horizontal when the bracket is boat mounted, a second ball joint universally connecting the second end of the hydraulic cylinder-piston assembly to the upper bracket portion, and a drive train adapted to be connected to a prime mover, extending through the bracket and the propulsion leg, and drivingly connected to the propeller.
