Thermostats are devices that sense the temperature of a system so that the temperature is maintained at the desired set point or near to it.

NTC temperature sensor allows the module to intelligently control varied electrical devices based on the temperature. The thermostat in your MerCruiser Alpha monitors the temperature of the engine. Replacing the thermostat in your Mercruiser Alpha is definitely a DIY project, and you can find a new one at your local boat shop. Yes, you can temporarily run your outboard without the thermostat and not harm the engine. No, you can not remove the thermostat and continue running the engine for long periods of time without causing harm to the engine. At its core, a thermostat is simply the controls used to regulate temperature in a heating system. You can set a preferred temperature, and the thermostat works to keep your room or boiler at this desired level. If the home starts to drop in temperature, a thermostat switches the heating on to warm it up. A thermostat regulates the temperature of the water for engine cooling and keeps pressure in the cooling system to facilitate heat transfer from the heads and the cylinder walls. MerCruiser engines may also be equipped with a closed cooling system. This cooling system is divided in two separate sub-systems: one uses seawater and the other uses coolant (called “fresh water”).
