Welcome to the forum.
As stated, not the best boat and you will not never nope turn a profit on restoring it.
If it's your hobby, go for it. I had a 2150 L Drive, really liked the boat and how it handled.
Mercruiser all the way.
Oh and on the transom tilt motor up and push as hard ad you can down should be zero flex and try to tighten motor mount bolts should not be able to move much at all. I had a boat once was able to get a few turns then noticed the washer had sunk in meaning transom was rotten.
Sorry my dixelia gets to me especially on the weekends with some wine. I will clarify another day but winch needs to be raised and the eye needs to be below the stop.
I'd prefer to have the eye below the stop as an extra stop if needed. Too low and it will help launch in a sudden stop and stern straps won't help that.
