The valve that opens or closes based on the temperature in the cooling system of an outboard is a thermostat. When the thermostat is set closed, it prevents cooling water from flowing through the outboard, raising the operating temperature of the boat engine. The thermostat opens when the temperature rises, allowing coolant to circulate through the outboard and lowering its working temperature. Temperature ranges are critical for ensuring the engine's longevity. You don't want the engine to overheat, causing internal damage and finally locking up. The Engineered Marine Products (EMP) thermostat Kit 140 degrees exceeds customers' expectations regarding its reliability and lifespan. It also incorporates a gasket for optimal support.
