Abstract
An air supply conduit system for a watercraft having an air breathing internal combustion engine within the watercraft interior includes at least one air supply conduit extending from an outlet end located in the watercraft interior to an inlet end located outside the watercraft. A noise suppressing resonating chamber connected to the air supply conduit damps noise from the internal combustion engine from the outlet end of the conduit towards the inlet end thereof. The air supply conduit may be positioned within the watercraft to minimize entrapment of liquid within the conduit and the noise suppressing resonating chamber. An inlet fitting including a noise suppressor is located at the inlet end of the conduit.
