Hello all,
My 88 3.0 mercruiser runs great for about 30 minutes while tubing, all of a sudden it starts to sputter and slows down and speeds up at same throttle position. I have always had small issues with it starting when it runs for a while. Last year I replaced the carb, fuel line, fuel filter, plugs, wires, distributor, and starter. It seemed to be running great until we stated taking it tubing. Not sure if it’s the carb settings, bad gas or who knows? I ran some sea foam through a tank and not it’s starting and idling rough on top of it. Any thoughts or suggestions would be appreciated.
