    Mercruiser 4.3 LX not firing

    Did you read the link Rick left in post 8? Yes, but so could every other part in the ignition system. If you test then it can be narrowed down, otherwise buying and throwing parts at the problem may fix it, but may also add more problems

    95 Mercruiser 4.3 water in oil

    Could still do a compression test with intake off. Make a couple block off plates for the intake ports and pressure test the block thru the drain plug. See if it holds air, and if it does might be worth a try to reinstall the intake and run it

    My opinion: others do vary The boat manufacture made a good boat, they just may not have designed it so it would last. So I wouldn't add more supports unless you want to. Add more FB and make it better then before is all good
