It is a good hull design but probably needs a proper re-restoration; the transom plate makes me think it might have gotten a band-aid resto.
Without good documentation, the previous work is likely not worth a lot and even then needs a good look - think about paying a good marine surveyor if you are serious.
My guess is that it needs a transom and a recore of the decks - maybe a fuel tank if that was not properly redone (if done at all). All original hardware needs to be looked at closely too.
If you
like doing the work and the price is right (cheap), it might be a good/fun thing but you won't end up in the black. (Been there n done that - oh yeah, I'm doing it again 'cause I'm stupid
)
If you are paying for the work you will probably be upside down pretty quick so you'd better love it or be comfortable lying about it.
The motor is a wild card in it... maybe good or maybe not.
If you do it, then welcome to the group insanity...
