Tuna its standard crapola you run into when you buy anything used. Distance just adds to the questions. Plus your opinion of what is OK or acceptable can be completly different from the guy you are buying it from. Some people have no real pride in what they own, I've found for my purchases over the years that one of the key things I look for is the fellow who is torn about even selling her because he really loves the boat or is so proud of his work/maintenance of her.
I'm 52 years old and I just counted that I have had nine boats over the years, all used, and each one had one or more major issue, or a combination of major and minors.
But I enjoyed working on each, learned something from them all and in the end would not have really changed much.
BGrace is right on the money with his comments, his experience common.
Take stock in what you have, most times its best to lay the boat out in immediate must do's, for safety of you and yours, reliabilty on the water and pure functionality to pursue your interests.
Then lay out some improvements you need or want to make, usually these are some comfort items and cosmetic improvements.
If your hull is solid, floors and transom good you are ahead of the game. Wiring from the factory was not very good on these Wellcrafts to begin with and twenty some years of fiddiling and repairing and adding equipment by various "experts" usually results in a conditon that looks like a bowl of spaghetti.
You'll sort it out and you will repair it to the level that makes you happy and in the end you will be cruising the left coast with those great sunsets, maybe with the wife and a couple of cosmos or a couple of rods trolling out the back. Either way smile and enjoy the ride.
