Welcome aboard
as indicated above, it will be expensive
if all the paperwork needed to get ownership is there, and you want a project that your wife is comfortable with you spending thousands of dollars and hundreds of hours on, then go for it.
estimate about $3-4k for hull work, about $2k for interior work, and if the motor or drive needs minor work, estimate a minimum of $1k for that (up to $4k if you have to replace everything) and about another $1-2k for miscellaneous.
If it does not have a title for the boat/trailer, I would highly suggest you walk away
