Kind of heating up?
Not to change the subject but my A-4 has begun operating at about 180 during normal cruising speeds, but smetimes will creep up to the 190s and then go back down. I can watch the guage start going up but it then starts to go back down fairly fast. A couple of times it was probably 195 which I do not like. Their seems to be a good amount of water coming out of the exhaust when this happens. I'm thinking new thermostat? New impeller or to be safe both. Also if I need a new thermostat do I purchase the moyer marine 140 degree. What temp should the engine be running? It does not have a sealed cooling system.
