ABSTRACT OF THE DISCLOSURE A marine propulsion device comprising a support bracket attached to a boat hull, a propulsion unit, a tilt pin connecting the propulsion unit and support bracket for tilting movement of the propulsion unit, and an extendable and retractable cylinder-piston assembly for facilitating manual tilting movement of the propulsion unit. The cylinder-piston assembly comprises a cylinder, a piston located in the cylinder for reciprocative movement therein, a piston rod connected to the piston and extendable from the cylinder, and lugs connecting the cylinder-piston assembly to the support bracket and the propulsion unit. The marine propulsion device also includes a predetermined quantity of incompressible fluid partially filling the cylinder, a gas with a pressure higher than atmospheric pressure filling the remainder of the cylinder, and a manually operable mechanism in communication with the first end and the second end of the cylinder for selectively preventing fluid flow between the first end and the second end of the cylinder.
