Abstract:
1. A marine engine exhaust system, comprising: a first manifold on a side of an engine; a second manifold on a side of the engine opposite the side of the engine that has the first manifold; a first conduit in fluid communication with said first manifold such that a first gas exiting said first manifold is transferred into said first conduit, wherein said first conduit has a bend that changes the downstream direction of flow of the first gas in the direction towards the side of the engine having said second manifold, wherein the first gas is isolated from cooling water through said bend of said first conduit; a second conduit in fluid communication with said second manifold such that a second gas exiting said second manifold is transferred into said second conduit, wherein the second gas is isolated from the cooling water at least part way through said second conduit; and a third conduit in fluid communication with said first conduit and said second conduit such that the first gas exiting said first conduit is transferred into said third conduit and such that the second gas exiting said second conduit is transferred into said third conduit, wherein said third conduit is configured such that the first gas and the second gas merge therein, and wherein the cooling water is merged with at least one of the first gas and the second gas before the first gas and the second gas merge in said third conduit.
