ABSTRACT:
A watercraft can include an engine having a crankshaft with its output end extending rearward of a crankcase and a supercharger for compressing air feeding it to the engine. The supercharger can be located forward of a rear end of the crankcase. An exhaust pipe, designed to discharge combustion gas out of the watercraft, can be disposed above the supercharger. Forward of the supercharger, an intake box having an intake duct can be provided. An intercooler can be located beside the supercharger, through which the supercharger feeds the compressed air toward the engine.
