の油圧操作機構。 A shuttle spool is provided that slides back and forth using pressure oil from a hydraulic pump that rotates forward and backward, and a protrusion on the shuttle spool is used to check valves for return oil in the oil chambers for raising and lowering the hydraulic cylinder for vertical movement. In the hydraulic system for vertical movement of a marine propulsion system configured to open and close, by manually pushing the return oil check valve device toward the shuttle spool side, the oil chamber for raising and lowering the hydraulic cylinder is opened, and the oil chamber for raising and lowering the hydraulic cylinder is opened. A hydraulic operating mechanism for a marine propulsion device, characterized in that the marine propulsion device can be moved up and down by.
