  • Patent number: 5259797
    Abstract: A marine engine exhaust system and method utilizes first and second enclosed, generally tubular chambers having generally parallel lengthwise dimensions and internal intermediate exhaust passageways spaced along the lengthwise dimension of the second chamber for circulating the exhaust gases through the first chamber, laterally through the intermediate exhaust passageway into the second chamber, along the lengthwise dimension of the second chamber and thence out of an outlet exhaust passageway which passes through the second chamber wall. An outer portion of the second chamber is integrally formed with an outer portion of the first chamber to enhance structural integrity.
