ABSTRACT:
An improved muffler for silencing the exhaust emitted from a water cooled marine engine employing a first outer housing encompassing a generally cone shaped inner member and forming a silencing volume therebetween and an angularly disposed inner planar baffle, inlet path, outlet path, ramp, and aperture for exhaust gas and cooling water to fluidly communicate from an inlet to an outlet resulting in a diminution in flow velocity so as to attenuate the exhaust noise.
