Abstract
A marine engine has an exhaust system including a catalyst cooled by a flow of coolant, a coolant injector that injects coolant into the flow of exhaust at a point downstream of the catalyst, and a sensor arranged to sense a characteristic of the flow of exhaust, such as oxygen or carbon monoxide level. The engine controller is configured to control an air/fuel ratio of the engine as a function of the sensed exhaust flow characteristic.
