Welcome aboard Trey!
Wow, you have a lot to consider.
The power you have in hand is perfect for that hull. That's the good news.
It is exactly the same hull as an O/B 19-6 in terms of deadrise, beam, length, etc.
Main thing, the hull itself. Is the motor still in? Where is the tank located? If changing to outboard power, the tank will need to be relocated for balance...and you'll need a new one regardless. The transom was never designed for O/B power...that will need to be rebuilt. If she is an original, unrestored '72...take a look at the rebuild threads here. 95% of 70's boats have shot transoms, waterlogged stringers, and rotted decks. The threads tell sometimes sad stories, but happy endings.
Of all the 70's 19-6's here: only two are totally original, excellent condition. One is a Great Lakes boat. The other is in Indian Rocks Beach, Tampa area. Both are barn finds.
Be prepared to spend a minimum of 10K.
Spend a LOT of time on the rebuild threads here before you make this purchasing decision. That ride isn't going anywhere. $500 should buy it, you can scrap the block and get back some of that.
This is not what you want to hear, I know. I learned the hard way, and if I can save anyone here a nickel by urging caution, I will. The first 22-2 I bought was in good faith...and was screwed by an 80 year old man. It wasn't fun.
Will be unable to follow for a few days, no internet. The boys will guide you well!
Best, and welcome
