LOL You just answered your own question.
What makes that whole deal seem impossible is when the person who last held a title for a boat is either dead, absent, or uncooperative. The DOR doesn't seem to understand (or care) how uncooperative dead men can be, and only lawyers know the secret password that causes them to instantly understand and begin to play nice.
Sooo, when you find a boat/motor/trailer you wanna buy and the "owner" says they can't produce the titles you just tell them you'll take it for 550.00 less than what they are asking because that's what it'll cost you to make it "legal", or you'll pay the asking price if THEY can provide title(s) Most will at least try for 550.00
