Abstract
A jet propulsion system for a small watercraft including an arrangement for isolating the sound of water flowing through the water inlet portion of the jet propulsion unit from the occupants of the watercraft. This silencing is provided by providing a double wall on at least the portion of the jet propulsion unit water inlet portion juxtaposed to the passenger compartment to provide an insulating jacket. Water may be filled in the insulating jacket and this water can be derived by filling it with the coolant which is circulated through the engine.
