Abstract
To provide an exhaust structure for a jet propulsion watercraft which can simply achieve a reduction of the exhaust noise. In the exhaust structure for a jet propulsion watercraft, a water jet propeller is provided in a pump room of a watercraft body. An engine for driving the watercraft is connected to the water jet propeller. An exhaust opening of an exhaust pipe is attached to the engine and is exposed to a pump room. A resonator for sound deadening is provided for the exhaust pipe. Further, in the exhaust structure for a jet propulsion watercraft, the resonator is bent in a meandering state such that bent portions thereof are positioned adjacent to each other so that the entire resonator has a substantially flat plate-like configuration. The resonator having a plate-like configuration is laid along a ceiling wall of the pump room.
