Muffler for marine engines

Image Number 3 for United States Patent #5504280.

An improved muffler for silencing the exhaust emitted from a water cooled marine engine comprising a housing enclosure having a corrugated spacing means disposed within the housing partitioned by an angularly disposed inner planar baffle, the housing having an inlet for the exhaust gas and cooling water to fluidly communicate with a lower silencing chamber wherein the exhaust gas and cooling water are forced through a spacer passageway formed from the corrugated spacing means into an upper silencing chamber resulting in flow reversal and diminution in flow velocity so as to attenuate the exhaust noise, the exhaust gas and cooling water exiting the upper silencing chamber through an outlet fluidly communicated therewith and disposed collinearly with the input. The upper silencing chamber acting as a back flow preventor.
