    1985 4.3l v6 mercruiser piston rings

    measure the bores with a bore gauge. you will need more than just the rings unless the block was brand new sitting on a shelf in a time capsule. if it has any hours on it, the bores are no longer round and will be tapered. this means that you will require a minimum of a 0.010 oversized...

    Mercruiser 4.3 L Manifolds

    some may last forever in fresh water. many failed due to core shift issues (cant inspect them easy) and when that happens they kill the motor. Merc started using the batwings you have in 1996 I think they quit using them in 2000 your motor is 26 years old. so why worry about a service life...

    1970s winday day cruise foam core deck

    The main reason for delamination is too low a density of foam (based on many threads on boat design). The foam starts to break down due to loading If the top layer is delaminated, you need to remove the whole outer skin. I would also take a core sample (about 1" in diameter) to see if the...
