ABSTRACT:
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.
