PROBLEM TO BE SOLVED: To immediately stop a marine engine causing an abnormality, and surely prevent the breakage by arranging a hydraulic switch which is operated when the hydraulic pressure falls to give an alarm or urgently stop an engine on the terminal part of a hydraulic piping extending from the engine to an oil pressure gauge or on the vicinity thereof. SOLUTION: Oil pipes 8a, 8b are arranged extending from the hydraulic circuit of a marine engine 1 to a first adapter 7 having an oil pressure gauge 4 and a hydraulic switch 5, which is set on the hull side, and a third oil pipe 8c branched from the oil pipe 8a is extended to a second adapter 6 having a hydraulic sensor 3 and another hydraulic switch 5. The sensor 3 is wired to an oil pressure gauge 2 arranged in, for example, a pilot house. The switch 5 is wired to an alarm device for alarming a drop of oil pressure and/or an emergency stop device for stopping the engine, whereby the occurrence of an abnormality is alarmed, when the oil pressure falls by the abnormality on the engine 1 side, and the engine 1 is also urgently stopped. |
