THERMOSTAT from Sea Star Solutions 18-3668. This device controls the flow of a heat transfer fluid, turns on or off heating and cooling units, and maintains the proper temperature. The engine and radiator are kept apart until a certain minimum temperature is reached. If it weren't there, the engine would lose heat to the radiator continuously and take longer to warm up.
Key Features:
- Before the water gets too hot and overheats the outboard engine, it is able to escape.
- prevents heat transmission from the cylinder walls and head while regulating water temperature to enable for engine cooling.
- The thermostat meets or exceeds the manufacturer's requirements.
