Re: Is this boat a good deal?
If indeed all it does need is a motor, and your capable of doing the work yourself, it can be a fair deal. If you have to pay a marina or if the rest of the boat needs work, it may have been more worth your money to invest in a better boat even if it needed the same work.
Most of the Bayliners I see end up at the dump, most were bought by first time owners and never got proper care and storage. Everyone I've run across so far has been a soggy, wet mess needing new floors, transom, and flotation foam, besides any obvious mechanical problems.
Myself, if I'm going to go through all that work to fix up a boat, I'd rather put my time and money into one that is better built from the start, and one that will maybe be worth a bit more if I decide to sell it.
On the bright side, even if the boat turns out to be not worth the trouble, if it's on a decent roller trailer it may well have been worth what you paid. You could also part out the rest of the boat to recoup some or all of your investment and find a nicer project.
I'd start off by looking real close at the deck and transom and maybe even weight it and compare it to the advertised weight, if it's way heavier, it's full of water logged foam and rotted wood.
