"I have a 1988 FourWinns with the Cobra 3.0 and it has been reaching 240+ degree when first starting but will eventually cool down if I idle it at high RPM's for a minute or so. I replaced the impeller and thermostat with 160 degree but the temperature with the muffs on in the driveway is 185 degree. Do you guys know if this is normal operating temperature, it seems kind of high to me? Shouldn't it be running at or below 160? The engine's water pump is the only thing left that I can think of, is there something else I should be looking at?"
