  • 1992 Four Winns 454 King Cobra Rev Problems

    Guys I have a 1992 Four Winns 220 Horizon. The engine is a 454 carbureted model. This boat has been awesome for me for the 10 years that I have owned it. We kept it in storage for one season and ran into some problems when we got it out last year. So last summer it developed an issue where it would not go over 25mph on the initial run. The boat would miss when you tried to peg the throttle down above 25mph. But after you shut the boat off and let it cool down it the issue subsides and the boat runs like it should. You can go on a 15 mile run and not have any issues. So my mechanic rebuilt the carb replaced the fuel filter and we still are having this issue. I keep my boat out of state so it is hard for me to get my hands on it without a 4 hour trip. My mechanic is stumped and frustrated on what it could be. It is getting harder and harder to find people that are willing to work on Omc configured boats around here.
    It seems like I have some kind of an electrical issue going on. It acts like I am hitting a rev limiter. That's the only way I can describe it.
    Does anyone have an idea on what could be causing this? Thanks

    Does it have electronic igniton and could the module be breaking down when it gets hot?

      It has the spitfire ignition. It only does it when the boat is cold,

        OK then is the choke working and opening as it should? Which carb, the Rochester Quadrajet or Holley 4bbl? Rochester has an exhaust heated crossover that opens the choke, Holley has an electric choke
