ABSTRACT:
A muffler for an exhaust system of an outboard engine is constructed in two parts, one being longer than the other with the longer portion being of standard length for various engine applications, while the shorter length muffler section is constructed to have variable lengths to accommodate various engine and propulsion unit applications. The lower muffler section is resiliently mounted to reduce transmittal of vibrations to the engine housing and associated structure. By constructing one of the muffler sections of a standard length for all engine applications, molding costs for various applications are reduced.
