The pivoting structure may not be wide enough though.
You would lose one of the big advantages. When not making way (ie: the rudders aren't doing anything to help steer), I can turn the outboard and push or pull the rear around. It makes a big difference in tight quarters manuvering. (remember there will be no prop wash across the rudders)
If you add the sail drive to your 220#, you are probably trying to lift
north of 260#. You would probably have to reinforce the bucket and add a winch
of some sort to raise and lower it.
Also, outboards are designed to be exposed to water
and take the occasional splash. Most diesel installations prefer a dry space to live in. How would you protect the motor?
The real killer, if you look at the bucket, the roof above it slopes down and narrows quickly once you get ahead of the transom. You would either have to extend the bucket further out the back or do major fiberglass
surgery to make room for it.
If you are just looking for a project
for the sake of a project, go for it and let us know how it turns out. If you are looking for a practical solution, this is a bad idea.
As someone else pointed out the late model 3400's and most of the 105's are diesel powered but they completely redid the back to provide a space for the engine
and use a special I/O unit (what I've seen, they are the biggest maintenance
headaches on a lot of the boats).
