<p>A hydro-tilt apparatus for an outboard engine (1) comprises a manual valve (20) to open and close an oil passage between an upper oil chamber and a lower oil chamber of a hydraulic cylinder (13) and a gas chamber (19) that compensates for the oil displaced by the piston rod (18) as it retracts into and extends out of the cylinder (13). The manual valve (20) and the gas chamber (19) are positioned in series with each other, parallel to and alongside the cylinder (13). Thus, the hydro-tilt apparatus secures adequate capacity for the gas chamber (19) and has a compact structure in length and width which is well suited for use on small outboard engines (1). The manual valve (20) comprises two one-way valves (31,32) coupled via a spring (33). A means for operating said one-way valves (31,32) is capable of operating said valves in three modes: both valves closed, one valve open and one closed, and both valves open. <IMAGE></p> |
