ABSTRACT OF DISCLOSURE Disclosed herein is a marine propulsion device including a tilt hydraulic cylinder-piston assembly connected between a boat mounted member and a propulsion assembly, a trim hydraulic cylinder-piston assembly including a trim cylinder fixed to the member and having therein a reciprocably movable trim piston having a piston rod adapted for releasably engagement with the propulsion assembly, a reversible pump effective when operating in a first mode, to supply hydraulic fluid under pressure to a first port and to provide suction at a second port and effective when operating in a second mode, to supply hydraulic fluid under pressure to the second port and to provide suction at the first port, a first conduit communicating between one end of the tilt cylinder and the first pump port and including a first valve biased so as to releasably prevent flow from the first end of the tilt cylinder to the first pump port and so as to permit fluid flow from the first pump port to the first end of the tilt cylinder in response to the presence of hydraulic fluid under pressure at the first pump port, a second conduit communicating between the first end of the trim cylinder and the first pump port independently of the first conduit, and a piston communicating with the second pump port for actuating the first valve against the bias thereof and in response to the presence of hydraulic fluid under pressure at the second pump port so as to permit hydraulic fluid flow from the first end of the tilt cylinder to the first pump port without affecting the trim cylinder-piston assembly.
