Abstract

A personal watercraft is disclosed as having a forced air induction system that is particularly suitable for aftermarket installation. The induction system includes support structure for supporting the compressor in a non-cantilevered manner within the watercraft body. In supercharger applications, the induction system provides a drive arrangement for powering the supercharger that eliminates or reduces the need to remove the jet pump driveshaft. The belt drive embodiment includes a pulley having a fluid flow passageway extending inwardly from the belt-engaging surface so as to relieve any hydrodynamic forces between the belt and pulley. A body-engaging plate of the support structure is associated with a high-friction material pad for frictionally enhancing the securement of the plate to the body. The support structure further includes a fire extinguisher mount removably supporting a fire extinguisher within the interior space of the body.
