PROBLEM TO BE SOLVED: To quickly stop a vessel by switching a forward clutch to a backward clutch and finding clutch hydraulic pressure from an engine speed with which an engine does not stop, at the time of stopping of the vessel during forward running. SOLUTION: When crash-astern is carried out, a detecting device 8 detects an engine speed at that time, for example, and the detected engine speed is inputted to a controller 11. Clutch hydraulic pressure with which engine stall does not occur corresponding to the engine speed, namely, a crutch hydraulic pressure Pw set lower than hydraulic pressure in an engine stall limitation is previously stored in a memory device as a table. The controller 12 controls a clutch hydraulic pressure control valve such that the clutch hydraulic pressure Pw corresponds to the engine speed inputted from the detecting device 8 while referring to the table. That is, when the engine speed is high, the clutch hydraulic pressure Pw is set high, and when the engine speed is low, the clutch hydraulic pressure Pw is set low.
