ABSTRACT OF DISCLOSURE Disclosed herein is a marine propulsion device including a member adapted to be attached to a boat hull, a propulsion assembly pivotally connected to the member for vertical swinging movement, a hydraulic cylinder-piston assembly connected between the member and the propulsion assembly and including a cylinder having opposed first and second ends, a first sealed reservoir adapted to contain pressure fluid, means for introducing pressurized gas into the reservoir, a second sealed reservoir, a pressure relief valve communicating with the second reservoir, and a control valve structure comprising first, second, and third valves having a common actuator movable between first, second and third positions, which first valve communicates between the first end of the cylinder and the first reservoir and is open when the actuator is in the first position and is closed when the actuator is in the second and third positions, which second valve communicates between the first reservoir and the first end of the cylinder ant is open when the actuator is in the third position and is closed when the actuator is in the first and second positions, which third valve communicates between the second end of the cylinder and the second reservoir and is open when the actuator is in the first position and is closed when the actuator is in the second and third positions. Also included is a let-down valve assembly which communicates with the second reservoir and with a fourth valve which forms a part of the control valve structure and which is open when the actuator is in the second position and which is closed when the actuator is in the first and third positions. Also included is a conduit extending between the first and second reservoirs and including a spring biased valve permitting flow from the first reservoir to the second reservoir and preventing flow from the second reservoir to the first reservoir.
