Abstract
An exhaust system for a marine engine comprising liquid-cooled manifold and catalytic converter assemblies. Each assembly uses a separate cooling system to cool either the exhaust manifold or a shell inside which resides the catalytic converter. The housing or shell containing the catalytic converter uses water to cool an exterior surface of a water jacket to an acceptable temperature conforming to federal regulations. The liquid-cooled manifold assembly may use either water or glycol to cool outer cooling tubes surrounding exhaust tubes extending from the engine block to the catalytic converter assembly.
