Punctuation and individual sentences would help clarify your problem.

Most props have a rubber hub and if you have a spun hub the boat will go slowly but when you apply power the prop spins on the hub and does not provide any propulsion. So a spun hub is one possibility.

So the prior owner put on a new prop but that did not fix anything. It that what I am reading in your initial post?

There is also the coupler bolted to the flywheel that could be slipping.

The only way this boat makes any financial sense is if you can do do all the work yourself. You are saying at the end of your post that you may have to bring it to a shop. The shop will probably charge $100 and hour.

Outdrives are expensive. Your boat is not worth very much.
