ABSTRACT:
A catalytic exhaust system for an outboard motor having an engine positioned in a cowling thereof is disclosed. The exhaust system leads from an exhaust port of the engine to a discharge from the motor. A catalyst is positioned in the exhaust system for catalyzing exhaust gases. A first port is positioned in the exhaust system downstream of the catalyst through which an exhaust gas probe may be selectively extended for obtaining an exhaust gas sample. Additionally, a second port is preferably provided between the catalyst and the first port and through which an exhaust gas temperature sensor extends.
