Abstract
An exhaust system for a small watercraft wherein exhaust gas can flow smoothly includes a water muffler in the exhaust system for an engine incorporated in a small watercraft. An exhaust pipe is connected to the water muffler extending upwardly once and then extending downwardly in such a manner as to have a substantially U-shape. Spiral baffle plates are provided for spirally introducing exhaust gas on an inner face of the U-shaped exhaust pipe. Since the baffle plates are provided on the exhaust pipe, cooling water and exhaust gas can be separated from each other.
