Abstract

An exhaust system is for a marine propulsion device having an internal combustion engine. The exhaust system comprises a catalyst housing having a housing inlet end that receives exhaust gas flow from the internal combustion engine and an opposite, housing outlet end that discharges the exhaust gas flow. A catalyst is disposed in the catalyst housing. An outlet collector receives the exhaust gas flow from the catalyst housing. The outlet collector comprises a collector inlet end that is engaged with the housing outlet end. One of the collector inlet end and housing outlet end overlaps with the other of the collector inlet end and housing outlet end at a joint. A seal is disposed at the joint between the collector inlet end and the housing outlet end. The joint is devoid of a cooling water jacket.
