A marine muffler capable of handling both marine engine exhaust gas and marine engine cooling water includes a double wall baffle partitioning the muffler interior so as to function as a cooling water conduit. The cooling water conduit includes an inlet disposed external to the main muffler housing and an outlet configured and disposed so as to discharge the engine cooling water into the exhaust duct connected to the muffler outlet. The muffler is thus able to convey the engine cooling water through the muffler housing within a dedicated conduit while maintaining the cooling water separate from the exhaust gas. A muffler that is adapted to handle both the exhaust and cooling water flowing from a marine engine allows for the elimination of engine cooling water piping.
A marine muffler having a housing defining an exhaust inlet and an exhaust outlet, wherein the improvement comprises:
In a marine propulsion system having an internal combustion engine generating exhaust gas, wherein the engine further includes a cooling water intake and a cooling water discharge, and wherein a first portion of discharged cooling water is injected into the exhaust gas, and a second portion of discharged cooling water is not injected into the exhaust gas, and wherein the exhaust gas and discharged cooling water entrained therewith pass through a marine muffler, the improvement comprising:
A method for discharging marine engine cooling water and marine engine exhaust from a marine vessel, said method including the steps of:
