Bought boat three weeks ago and ran two and a half tanks of gas through it. Was going back to the slip and the boat went from going wide open to only idling. Replaced plugs wires and fuel filter and can't figure out why it won't run right. Only does it when u get to around 3000 rpms. Acts like it is spitting and sputtering when it gets to 3000rpms. Run fine before that.
