CA 2351293
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.
