    Abstract: A noise reducing system for a personal watercraft. The system includes a pump insulating system which insulates the pump housing from the hull. More particularly, the pump insulating system includes at least one insulating attachment for connecting a pump housing to a supporting surface of a personal watercraft. Such insulating attachment includes an insulator having a portion mounted between the pump housing and the supporting surface. Advantageously, the system also includes a resonator and a shield, both mounted on the exhaust system, and an insulating material mounted inside an air intake pipe.

    Abstract: A personal watercraft with an exhaust system including a first and second mufflers each disposed in opposite sides of the hull. A manifold pipe communicates the engine with the first muffler. A transfer pipe communicates the first muffler with the second muffler. An outlet pipe communicates the second muffler to the atmosphere at an exhaust point located at an opposite side of the hull. The outlet pipe has a raised portion between the second muffler and the exhaust point so that only rotation of the watercraft in a first rotational direction will cause entrant water in the outlet pipe to flow into the second muffler. The transfer pipe has a raised portion between the first and second mufflers so that only rotation of the watercraft in second rotational direction about the longitudinal axis opposite the first rotational direction will cause water that has flowed into the second muffler to flow into the first muffler.

    Abstract: A watercraft comprises a hull, an internal combustion engine, a propulsion system, and an air/water separating device. The separating device comprises a container having an inlet port and an outlet port. The inlet port enables at least ambient air to enter the container and the outlet port is communicated to the air intake of the engine. The separating device has structure providing spaced apart generally vertical surfaces that define a plurality of elongated tortuous paths between the inlet and outlet ports. The tortuous paths have one or more angular portions and are positioned and configured such that the ambient air passes through the elongated tortuous paths so that water suspended in the air is separated from the air as the air passes through angular portions of the paths with the separated water flowing downwardly along the surfaces to a bottom of the container by gravity.
