    My jet boat boat turned 5600 rpm with an A cut impeller. I Changed the cam to more lift and duration... still 5600 rpm. Changed impeller to a B cut still 5600 rpm. My thought is that I may need more carb? It doesn't fall on it face or nose over... just levels out at 5600. I have dual 660's on...
