Abstract
A personal watercraft catalytic exhaust system wherein an over-temperature sensor is provided that is effective to shut down the engine in the event the catalyst reaches a dangerous temperature. The engine, once shutdown, cannot be restarted until the temperature falls below a predetermined temperature which may be lower than the overheat temperature. In the process of stopping the engine, it is slowed down first so as to give the rider additional warning that the shutdown procedure will be initiated.
