    Can the engine and transmission be removed without dry docking.
    I have a 1992 370 sundancer with 454 mercruiser and v transmission

    Well I go first, if you pulling the engine / trans, hauling out is the least of your cost.

    I believe.. with the v-drive you have to pull the shaft out enough so the trans can be lifted up. This typically means pulling the prop at a minimum, which while could be done in the water, will be most challenging. Then, depending on how the shaft lines up with the rudder, you may need to drop the rudder as well. I’ve got a 92 400 Express (no v-drive) and had to drop the rudder to get the shaft out. Finally - the apparatus you have (or create) to lift everything out would be next. The final challenge would be the reverse of everything thing above. Im sure where there is a will there is a way - but given the challenges, I would pull the boat and block it up.

    Then, depending on why your pulling, and assuming you have twins, now would be the time to pull the other one. Also good time to pull shafts completely and check/replace cutlass bearings and clean/repack stuffing boxes (or replace seal/face if you have dripless). In for a penny, in for a pound - yes, hurts a bit, but its about opportunity, and kinda like doing it once instead of twice.

    So, whats the story behind pulling the engine and trans?

    We replaced a V-drive while in the water, it would have made no difference to pull engine also. Now, we did the whole job it one day and the boat was never left alone.

    Water ingestion so I feel safer with going through both engines just to be sure. Thanks for the advice. With the shaft passing through the tranny I figured it would have to come out of the water

    Yeah, out of the water. Pulling the shaft vs pushing is the key. The rudder will be in the way of the prop but the shaft is offset of the rudder. From the coupler to the back end of the trany is more than a foot. Prop to rudder will be less.

    Are we sure the rudder is offset? He has a ‘92.. I have a ‘92 400 Express and the rudder is not offset, and I had to drop them to get the shafts out. Not sure when they started to offset them.
