New boats get a 190 deg thermostat. It will jump around a little, sometimes breaking 200, sometimes dropping to 170. Putting a new or bigger heat exchanger will not make the boat run cooler because your thermostat will close when you dip under 190 degrees, which cuts off flow to the heat exchanger. What is your issue? Are you getting overheat warnings?
