    STUCK 6.2L MPI

    Hard to know that unless you tell us…you intimated that you had to force the engine to turn over with a large torque wrench… so it spun freely you just wanted to see how much torque to turn over. is compression ok only other thought on hearing a ping is if a valve is hung up.

    STUCK 6.2L MPI

    You sure the engine was locked up? would think the gimbal bearing or u joints would be a likely culprit especially if water was in bellows. would be worth pulling the drive to check them given what you are describing

    Slow plane at high altitude 5.0L MPI, please help

    That’s the best if you can work with a shop and try them out. Looks good from my perspective What is your wot rpm now ? I figured if your wot was accurate you’d end up around 15” pitch

    Noise from engine compartment when steering left or right

    There is usually an anode there unless you have a mercathode system. That looks more like a beat up mercathode electrode but I can’t tell for sure

    2002 Mastercraft 5.7 harmonic balancer moving in and out

    I would tear it completely down and have a machine shop check rods pistons etc before reusing, get a new crank, do a valve job and go. if time is short and money is no issue a new marine 5.7 base engine is $5k...

    1990 vs 1992 4.3 block swap

    Sounds just like my 5.0 dont worry about it. Might be exhaust flapper nothing with engine. These pushrod V engines are not super quiet. Either turn up the radio, add more throttle, or drink more beer. Any combo of the three makes noise go away….

    Slow plane at high altitude 5.0L MPI, please help

    boat storage

    Dry slip seems nice as long as it allows for sour of the moment use . How long in advance do they need to get your boat in the water ?

    Risers - think I caught this just in time?

    I dont think that is from cooling water more likely condensation. The dry joint manifold prevents the leakage potential by separating the water and exhaust passages. also dont see any water streaks on them just rust and soot.
