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 passageways into the second chamber, along the lengthwise dimension of the second chamber and then out of an outlet exhaust passageway which passes through the second chamber wall and may also extend through a cooling water-collecting portion of the first chamber to achieve maximum muffling of the exhaust gas noise.
