I did it. I ended up with 6 dead and unchargeable golf cart batteries ("Generator was too loud"), a missing solar panel (storm), a missing 12' aluminum skiff with a good outboard, and several hundred dollars not paid. He says that he moved off of the boat and forgot to tell me, so he doesn't owe me, the solar panel shouldn't have blown off, and that the guy he lent my skiff to knew me but he can't remember his name. Tom maybe. I never saw it again.
It's been a long time and I'm still pissed.
By this time, if I still had the boat, the solar panel would be inefficient at best, the outboard dead and the batteries would have been replaced at least once again and I'm still pissed.
at least I sold the boat for what I had in it.
