OUTPUT SHAFT STRUCTURE OF PERSONAL WATERCRAFT

摘要

To prevent scattering of water in a watercraft body, prevent interference of a coupler with piping, and prevent deterioration of the piping. An engine 20 is mounted on a watercraft body with a crankshaft 20a of the engine 20 extending along the longitudinal direction of the watercraft body and a shaft 35 of a jet pump is coupled via a coupler 36 to a rear end of the crankshaft 20a in such a manner as to be disposed on an extension of the crankshaft 20a. A coupler cover 100 is provided for covering the coupler 36, and piping for cooling water, which is communicated to the jet pump, is fixed onto the coupler cover 100. A turbo-charger 70 is disposed over the coupler 36, and the piping is fixed on the coupler cover at a position between the coupler cover and the turbo-charger. The coupler cover 100 is turnable around the shaft 35.
