ABSTRACT:
A watercraft engine control system for controlling the temperature in the exhaust system to protect against potentially dangerous situations. If the exhaust temperature is sensed to be unduly high, a protective action is initiated. This protective action reduced in the flow of unburned fuel to the exhaust system either stopping of the engine or reducing its speed below idle. The protection action may be initiated either immediately or if the situation occurs for more than a predetermined time period.
