So I have been having the hardest time trying to figure out why I have no power at WOT, and why I cannot get off plane. I rebuilt all 3 carb's.... Float adjustments are correct, and I have 125 psi all 3 cylinders. But I still get fuel coming out of the carb's once the motor is turned off, and it runs like crap in the water.... and at WOT the boat will not come off plane. So I took the fuel pump apart and found out that the diaphragm in it was so cracked that the plastic housing inside the fuel pump broke apart. Could this cause all of my problems? Can a fuel pump cause it to leak fuel and run that bad out in the water?
