Exhaust system for watercraft

摘要

A watercraft includes an exhaust system having a connection pipe communicating exhaust gases from an expansion chamber to a water trap. The water trap is positioned generally toward one side of a center line of the watercraft and is angled relative to the center line. A downstream end of the connection pipe opens into a rearward section of the water trap. An exhaust discharge port opens through an upper portion of a forward section of the water trap. The discharge port is closer to the center line than is the downstream end of the connection pipe. An exhaust discharge conduit extends from the discharge port to an exhaust outlet formed through the watercraft hull on an opposite side of the center line from the water trap. In this arrangement, when the watercraft is rolled onto its side, the water trap will prevent water from invading the watercraft engine.
