Thanks for all the sage advice.
One thing I have under control is the budget. Selling 3 boats this year has left me with a good restore budget. Now adding the power will be another question...and one that I will not have to face for a while.
Really my question is. The outdrive and engine are out. I am thinking heavily on a parallelogram bracket. Do I rip out the transoms first and then the floors. Or do I do just the opposite? Or take the transom out. Leave open, and then take the floors out. Put a new transom in and then start building the floors.
It is daunting. However I wanted to do this, so I am mentally ready.
