| 摘要 |
The invention relates to a marine drive comprising a water-cooled internal combustion engine mounted in a boat, a shield mounted on the transom stern of the boat and supporting a universal joint housing and a pinion box connected to the universal joint housing and comprising a propeller arranged to be immersible in the water, an exhaust piping connected between the engine and the exhaust outlet carrying off exhaust and cooling water from the engine. The exhaust piping comprises a first part passing from the engine through the shield and associated with a second part passing through the pinion box and ending at the exhaust outlet, the connection between the first and the second part of the exhaust piping being open at least partly in order to unload the pressure in the pipe and to let out cooling water.
