First thing, it may be worth $500 or maybe $3000 to the eight buyer, there are some who adore the vintage craft. Overall it looks like a fair restoration project. The bad part that will send all but a few walking is all the hair on the paperwork. So you have a title signed by the named owner on the title(TN), and then signed by the buyer, which is not you? That is a uphill battle at any state DMV. Most folks simply won't deal with that hassle, so in the end, it may sell low($300) as a parts boat, not a resto. Want more money, you may need to get title in your name, then sell for more. It's like the old saying, how much is your time worth?
