    I had the same issue, all it needed was timing correctly.

    Mine was doing the same thing. Just ordered a carb rebuild kit, which is nearly impossible to find since i have the 4bbl carb and now im seeing that it may be the Thunderbolt box which will really suck since they arent made anymore

    I want to start a 4.3 LX/V6 Alpha One engine, can you tell me the firing order of the wires that go to the distributor.

    That looks just like my searay 200, judging from the interior. Hope you got it fixed.

    so in these engine a lot of different things could contribute to this issue I will start with lifters because it happen when he goes up to 1200 RPM

      Franklin the Man well I dropped mine off at the shop this week. I’ll find out in a week or two what’s wrong. I’ll let you know what my issue was.

      Steve H yeah it what I though was the thunderbolt electric timing box. Got it replaced along with a sensor and fixed the problem!

    i have this experience, for my case water go through cylinder 4 and problem come from gasket seal
    you can check by use a micro camera to check all inside cylinder after run engine 15 minute or run until engine have a problem signal
