Simply put, the engine thermostat is responsible for regulating the temperature of the engine. It helps to keep the engine from overheating by opening and closing the flow of coolant (a mixture of water and antifreeze) as needed. Let’s dive a little deeper into how a boat engine thermostat works.
Thermostat Opens - thermostats are designed to open gradually as the coolant/raw water in the engine blocks heats up, allowing hot coolant to pass through the heat exchanger (in indirect cooled engines) or for raw water to pass through the engine (in direct cooled engines) and out the exhaust.
The majority of marine thermostats open at 71°C and will be fully open at 82°C. As a rule, a clean system, under moderate load should operate at the lower end of this range whilst a dirty system under a full load might operate in the upper range.
