The boat has a 351,power slot, holly carb rebuilt, new fuel lines fuel pump, filter, converted to electronic ign, new plug wires, new distributor cap and button , new coil, new plugs, timing set to 10 btdc and has 750 hours. The boat runs great until I try to go over 4000 rpm and it feels like it is missing or like someone is pulling back on throttle for just a brief second then bounces right back. Have no problems pulling a skier or a wakeboard but when I try to go wot it will fall off. It does not keep me from hitting water so out of all problems to have this is probably the best problem to have but just aggravates the heck out of me and I am tired of throwing parts at it. Any ideas would be greatly appreciated
