OK…engine seems to run warm/hot…temp is not above 180 but I’m not running at 3,000 RPM, usually 2800. …couple of questions….
Lot’s of steam out the exhaust which I believe is more do to the balance of coolant water in either muffler or the mixture elbow. I sometimes remove the engine access panels on either side and I notice an easy 5-10 degree drop in temperature from the gauge. I’ve checked the coolant, impeller, heat exchanger for clear and the thermostat last year. Haven’t checked past the coolant elbow or into the muffer. Does anybody have any experience and does anybody introduce a fan back-up cooling system into the engine compartment and if so how do they and where do they vent on a sailboat through the hull or deck? Does the steam indicate overheating or based on temperature am I running fine? Other question, what RPM do folks run their engine at for cruising speed?
