Abstract
An exhaust pipe for guiding an exhaust gas from an engine into an exhaust gas expansion chamber defined within an extension case is connected to a protrusion of an oil pan which is mounted on a lower surface of a mount case that supports the engine at its upper portion. A breathing bore is formed in an upper portion of the exhaust pipe, and an outer side of the breathing bore is covered with a shield plate. Therefore, water cannot enter the exhaust pipe through the breathing bore. A cooling-water supply pipe for introducing cooling water from a cooling-water pump into the engine is formed with a cooling-water ejection bore which is located at a position in which it is not opposed to the breathing bore. Therefore, even if cooling water is ejected through the cooling-water ejection bore to the exhaust pipe to cool the latter, the cooling water cannot enter the exhaust pipe.
