The boat has 4.3L alpha 1 with the thunderbolt ignition system. Took out of storage had it winterized, ran fine last summer, put new plugs,wires,cap, and rotor on. Did not screw with timing or anything else of that nature, fuel had stabilizer in it when winterized. Took out for first time ran like crap, cant get full speed or even WOT out of it when its in gear. But idles just fine and can put it in neutral and rev it up then it will red line. Changed fuel filter, put heat in fuel, ran some Mercury Quick Clean through it double checked wires to plugs and distributor and still runs like crap! Pulled plugs they are wet fouled and the boat is burning gas like no tomorrow, called local boat shop said check timing i did and i messed with it when on water, didnt make one bit of difference either way (retarding/advancing). Ran all old fuel out of tank, put new stuff in didnt make a difference either. Anybody got any suggestions???? All i can think of now is a carb kit?
