A similar situation: My dad bought a 12-foot aluminum skiff about 1960. He kept it for about 25 years, then sold it to one of my cousins. He kept it about fifteen years and gave it to my nephew, my dad's grandson. I recently got it from my nephew and went to TPWD with an affadavit of its history from my nephew, seeking a title, as I wanted to put a trolling motor on it. They made me pay $25 to have a Game Warden inspect it, looking for a non-existant ID number. None found, she gave me an assigned Hull ID number, and I was able to title the boat for a total of $84! Inspection: $25. Title Fee: $27. Registration(two years): $32.
It IS possible to title old boats, in Texas, if you have a valid chain of possession. I have my nephew's 1961 Johnson to put on it. I'm not even gonna start dealing with that issue.
