ABSTRACT:
Sound muffling devices for marine engines for installation on the external portion of the transom of a marine vessel are attached in such a manner that any breakdown within the silencer causes no discharge of exhaust gases or cooling fluids into the interior of the vessel and the gases and cooling fluid continue to be discharged overboard. The silencer is designed to reduce, substantially, the noise level emitted by the engine under operation by the efficient mixture of gases and water through a series of baffles, with low resistance to gas flow that does not diminish engine efficiency. The gases and odors are emitted from the vessel at the centerline with distance and direction such as to reduce, substantially, emissions into the air environment. The device receives exhaust gas and cooling water from an exhaust pipe passing through the transom at the side of the boat and directs the gas athwart the boat to the center where it is exhausted. The device is designed to be used in pairs, with one for each of a pair of engines mounted side by side with an integral swim platform for its upper surface.
