Abstract
Two embodiments of exhaust systems for small watercraft that include cooling jackets circling a portion of the exhaust conduit. At least a portion of the water from the cooling jacket is mixed with the exhaust gases but at a point spaced substantially downstream of the cooling jacket so as to reduce the likelihood of water entering the engine through the exhaust system. In one embodiment, an additional cooling jacket is provided to which the coolant from the first cooling jacket is introduced and then discharged into the exhaust conduit. The second cooling jacket is disposed substantially downstream of the first cooling jacket.
