I have a 4.3 mercruiser. just replaced the fresh water impeller. was over heating at an idle. Not doing it any more. the problem is when i am at WOT. the temp gauge goes back and forth between 3/4 and 1/2. is this normal for these motors? i was thinking i would just remove the thermostat and see what happens? might just take a lil longer to warm up? any suggestions? thanks.
