摘要： A small watercraft comprises a hull having a longitudinal axis and an engine disposed within the hull. A tunnel is defined on an underside of the hull. A propulsion is driven by the engine and includes a jet pump unit disposed at least partially within the tunnel. An exhaust system communicates with the engine and extends to and terminates at an exhaust discharge outlet to discharge exhaust gases generated by the engine. The exhaust discharge outlet is located along the tunnel such that the exhaust gases are discharged into a space defined between the tunnel and the jet pump unit. An exhaust opening is located downstream of the exhaust discharge outlet and is defined between the tunnel and the jet pump unit. A barrier is located in the exhaust opening so as to form an exhaust sub-chamber in the tunnel upstream of the barrier.

摘要： An improved air-intake system and engine layout for use on a small watercraft provides for a lower temperature, vapor fuel/air charge with less water vapor content. The watercraft includes an engine-air intake system incorporating an air-intake box which inhibits the engine from intaking water present in the engine compartment, especially during high speed maneuvering. An extended flywheel case is also provided that prevents water located in the engine compartment from being sprayed by moving parts directly into the air-intake box. Furthermore, the improved air-intake system of the present invention incorporates external air-intake valves that prevent water from entering the engine and propulsion compartments through the air intakes while the watercraft is in an inverted.

摘要： An exhaust system for a small watercraft wherein exhaust gas can flow smoothly includes a water muffler in the exhaust system for an engine incorporated in a small watercraft. An exhaust pipe is connected to the water muffler extending upwardly once and then extending downwardly in such a manner as to have a substantially U-shape. Spiral baffle plates are provided for spirally introducing exhaust gas on an inner face of the U-shaped exhaust pipe. Since the baffle plates are provided on the exhaust pipe, cooling water and exhaust gas can be separated from each other.
