So I just repowered my 96 Sundancer with a new 7.4. Boat runs great but I was wondering what the coolant temp should be when running in the water? The gauge is reading just under 100 deg all the time. When I shut the engine off and let it sit for 10 min and turn the key on it will read 175 deg or so. As soon as I start the engine it will slowly go back down to 100. I am thinking this is normal. I have an open system, and it has a 160 deg. thermostat. It has 2 temp sensors in the housing, 1 must be for the gauge and the other for the overheat alarm?.
Thanks.
