Abstract
Abstract To utilize a small space in a vessel body efficiently and simultaneously augment the output power and realize a suitable water supply structure to an intercooler. A surge tank and an intercooler are provided between a supercharger and an internal combustion engine incorporated in the inside of a vessel body. The intercooler is disposed just below the surge tank, and an intake entrance from the supercharger and an exit to the surge tank are provided above the intercooler. A jet pump and the intercooler are in communication with each other directly by a cooling water hose, and cooling water is supplied from the intake entrance side into the intercooler.
