Thanks for reading!
Driving the pontoon at 3k rpm will drop to 2k then back to 3k then to 2.5k and so on. I pump the ball and the rpm will stabilize. I have replaced the tank primer ball and fuel pump. Also pulled the fuel pickup and it was spotless, Carburetors have been rebuilt twice by two different boat mechanics. The pontoon has never run right. It seems to be starving for gas or running lean. Any ideas on what could be causing this condition or what to check next.
