I recently purchased a boat with a 5.7L mercruiser and Rochester 2-GV. It was ran at a lake at an altitude of 6800' and most likely was tuned for that. I am using it at sea level. I've taken it out once so far and I believe it is running lean. The first and only time we took it out, the engine overheated at 2/3 throttle. We let it cool down and ran it for another hour at lower rpms (dumb, I know). Didnt overheat again. I pulled the spark plugs and they show a pretty lean condition (it was close to white at the tips). Do I have to rejet the carb?
I really would like to be on the water asap and don't want to waste time rejetting. Is there a carb I can purchase that is more easily tuned? I've spent quite some time redoing the upholstery, wood floor,and impeller. I'm burnt out. Summers almost over and I just wanna run the damn thing.
