ABSTRACT:
A marine engine exhaust system (10) and method for use with a marine engine. The exhaust system (10) includes a muffler body (20) defining an internal cavity (22) for receiving exhaust gases from a marine engine (12), the cavity (22) defining a reservoir portion (28) for holding water. The exhaust system (10) also includes at least one inlet passageway (24) communicating with the cavity (22) for receiving exhaust gases from the engine (12) and communicating them to the cavity (22). At least one water supply passageway (32) is provided which communicates with the cavity (22) and which is placed in fluid communication with a water supply such that water can be communicated to the reservoir portion (28). Further, at least one outlet passageway (40) is provided through which exhaust gases and water are ejected from the cavity (22). The outlet passageway (40) has an inlet port (42) disposed in the reservoir portion (28) of the cavity (22) and has an outlet port (44) exterior to the muffler body (20). The method of the invention includes the steps of communicating exhaust gases under pressure to the cavity (22) through the inlet passageway (24), and injecting water into the cavity (22) through the water supply passageway (32).
