Thermostat - Sierra Marine Engine Parts - 18-3633 (118-3633)

A thermostat is a temperature-controlled valve that opens or closes according to the temperature in the cooling system of an outboard motor. The outboard motor's working temperature increases when the thermostat is closed because it disrupts the flow of cooling water through it. Until the engine reaches its operating temperature, a thermostat prevents the cooling water in the block from boiling. After that, it opens to let the water out before it becomes too hot and damages the outboard motor.
