Engine will rev in neutral but not in gear
Boat ran 25-30 mph when first in water then got slower and slower. When you open throtle to full position it has no power in gear. However, when in neutral it revs like expected. I think I can hear the fuel pump running constantly, is it supposed to do this? Could this be fuel problems or transmission problems? Boat has new plugs, new rotor button, and fuel pump is 3 yrs old. Need help or suggestions.
