Abstract
This disclosure relates to a water-cooled engine for a boat, including apparatus to prevent the engine from overheating due to a shortage of coolant. The apparatus includes an air intake connected to supply fresh air to the engine, and an exhaust system connected to discharge exhaust gas from the engine. A duct is connected between the air intake and the exhaust system, and a normally closed valve is provided in the duct. A heat responsive device is provided on the engine to open the valve in response to a predetermined high temperature of the engine, whereby at least a portion of the exhaust gas is fed back through the duct to the air intake.
