Question by Deralict Boater: What is the difference between automotive and Marine thermostats ?
I have seem a lot of answers and they mostly refer to automotive Application.
1. So what is the correct thermostat temp range for a raw water cooled engine Raw water meaning not heat exchanged but cools with water taken directly out of the body of water the boat is operating in
2. Why is the temp range so important in this marine application
Answer by G-Web
the marine thermostat is lower temp than automotive because the engine in the marine engine will plug the cooling passages if Higher temps are reached . in salt water the engine will evaporate and deposit salt inside of the engine destroying it.
