Abstract:
A muffler for an exhaust system of marine propulsion device, comprising:an ingress conduit which is attachable in fluid communication with an exhaust manifold of an internal combustion engine; a water collection cavity connected in fluid communication with said ingress conduit; an egress conduit connected in fluid communication with said water collection cavity, whereby water entrained in an exhaust stream from said engine is induced to accumulate within said water collection cavity, in a lowest region of said ingress conduit, and in a lowest region of said egress conduit in response to said exhaust stream flowing sequentially through said ingress conduit, said water collection cavity, and said egress conduit, said ingress and egress conduits being in fluid communication with each other only indirectly through said water collection cavity, said water collection cavity defining a confined fluid path between said ingress conduit and said egress conduit through which said exhaust stream is restricted by said water collection cavity to travel directly from said ingress conduit to said egress conduit.
