  • Combination liquid-cooled exhaust manifold assembly and catalytic converter assembly for a marine engine
    Patent number: 8650864
    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.
    Type: Grant

  • Labyrinth seal adapter for marine propeller
    Patent number: 6835047
    Abstract: A seal adapter for reducing the escape of exhaust gases between an outboard motor and a propeller includes a substantially hollow cylindrical connecting member (71) having a shoulder (84) for dividing the connecting member (70) into a plurality of sections. A seal ring (80) is associated with one of the sections for engaging with an annular recess (76) located within the propeller hub (74) to provide a substantially tight seal.
