Billy D, I'm not doubting what you said. I don't have thermostats in my OMC, but I have restrictors (home made - take an old thermostat and cut the guts out and replace the outer portion). I do not use this boat in the winter. If it is cold or at start up I warm it up a while. The tolerances of the internals are set up to be at operating temperature. Unless one of his thermostats is malfunctioning, it should not be overheating.
So how's it coming obboy? FC.
