Abstract
A tilt actuator for an outboard motor wherein shocks acting on the actuator are initially dissipated at a first damping rate and then at a higher damping rate near the end-of-stroke of the actuator's piston. The tilt actuator comprises a cylinder, a piston, a piston rod and a damper member, the latter being cooperative with the piston in a first position to at least partially block at least one of plural damping passages in the piston thereby to restrict flow of fluid from the first chamber to the damping passages in the piston and in a second position that allows full damping flow of fluid to the inlet openings of the damping passages from the first chamber to the damping passages in the piston during movement of the piston in the second direction.
