Engine change

[marioxp]

After the ignition problem, the service engineer determined that the engine had insufficient compression on 2 of the 3 cylinders. Since I had a general engine service 2 years ago, I was not looking to take the engine apart again.

The decision has been made and I am replacing the MD2030 and sail drive MS25 with a new D1-30 and a 130S.

We have agreed with the service engineer that we will unscrew the old engine and take it to shore and put the new engine on the boat. After that, the crane will take the Bavaria 36 out to dry land and the repairman will take the old sail drive out and install the new engine and new sail drive.

I am working out a strategy for pulling the old engine out and transferring the new engine from the dock to the boat. The service engineer's advice is that it is easier to take the engine out to the dock while the boat is in the sea than when it is high up on a stand in dry dock. Does anyone have experience with this process? There are two of us, what would you advise me.

I did a repair with a volvo mechanic in murter on the saildrive (SD150) with  my D2-75. They separated the engine from the gearbox, when the boat was in the water. I see no reason why the engine couldn't also be removed while the boat is in the water. However, I cannot understand why the engine and the saildrive should be installed in two separate steps.

You can use the boom as a support for a chain hoist to winch the engine up the companionway. Support the boom by several halyards and protect all woodwork with old carpet.

Thank you for your help! I did the job of removing the engine and later the saildrive.

This is how we did it.
First I unhooked everything from the engine, then I unscrewed the saildrive, I unscrewed the steps at the entrance to the sailboat.

We didn't use the boom, but we tied the engine to the mainsail halyard, and topping lift. and We lifted it with the help of a winch. One person made sure that the engine didn't hit the woodwork, since the mast was high it wasn't difficult to move it off the side of the sailboat. And we did all of that while the sailboat was tied to the side in the sea.

Here in Dalmatia, service engineers have some of their own mantras, and they are convinced that it is very dangerous to do this when the sailboat is on dry land on a stand. Personally, I don't think that's right and it wouldn't lead to the boat overturn from the stand.
