Hey guys, I got a question pertaining thermostats. what is the difference with a 60c vs. 71c thermostat in a outboard? is it something to do with fresh water temp and salt water temp, and locations? I'm assuming fresh water is colder in certain locations which you would use the 71c thermostat and warmer water like salt water in certain location and use the 60c thermostat. is this correct? if someone has a better understanding this would please share the knowledge thank you.
