"I have been rebuilding a 1994
"I have been rebuilding a 1994 Maxum sr2 with a 5.7 Merc. Reworked the heads, replaced all gaskets, plugs rotor and cap. Boat did not come with a prop, it has 1.5 gear ratio on alpha one outdrive. 4 barrel carb.
I put a 23 pitch cleaver prop on her, I took her out today and got a max of 3600 rpm, then the engine would just lose power and slowly fall to about 2900.
On the way back in the engine started to skip and backfire. I could not get more than 2100 rpm a wot. I have not replaced the spark plug wire but plan on that tomorrow. I have a new fuel filter, but not sure about the quality of my gas. The tank was full when I got the boat, about 50 gallons in a 60 gallon tank. Not sure how long it has been sitting there so i put the new water removing fuel treatment in the tank and ran it. Any other thoughts on what I should be doing to make her run smooth and reach full rpm would be appreciated."
