    I was thinking of rebuilding a couple of DD 16v92 in frame for a friend, a lot of work. But I am concerned about space. Any of you guys have rebuild these monster on the boat, they are on a 50' something Hatteras sportsfish. I don't have a problem with engines, just the conditions of working on the boat. He doesn't want to take motors out.

    Wrong thread...

    Anyways,a friend started doing this but gave up due to horrible space constraints.
    Depending on the boat-some you have to cut them up- they may come out easy and be quicker to get done.

    If it were me I'd sign up to a Hatteras forum and ask the members

    Engines like that are often rebuilt in place. It's a real pain in the butt, though doable with careful prep and control. Controls would be isolation barriers (usually plastic sheeting) and working with a well cleaned (previously) compartment.

    Most owners get all fidgety, when you talk about cranes and lifting off the pilothouse to gain access, so this is an option. With reasonable care you can get a good job out of it.

    how do you rebuild a 16 92 in the boat, the pistons go in from the bottom. you would need enough room to lay the engine over. unless my memory decieves me you use a special tapered sleeve ring compressor and push the pistons in from the crank side. it has been a long time though.

    The engine MUST be lifted , although it need not be removed.

    UGH!

    On a Hatteras, the hatches over the engines lift so there is enough room to lift the engines. You will have to make a cradle to hold them in place while you work. I use two long 4X4 on the edge of the deck and a beam with legs across to hold chainfalls.

    It sounds like more work than I really want to do. I wouldn't mind if their were less pistons and turbos. Just a lot of work. I don't know where I would stick all the stuff as I took them apart.

    In the cockpit or aft deck and wherever else. Rebuilding an engine in a boat is hard physical work.
