I bought a 1968 Starfish about 3 weeks ago from someone who lives in Oklahoma. I obtained a title for the boat. The title contained a HIN, but that HIN is nowhere on the boat. My state requires boat purchasers to take a picture of the HIN or do a pencil rubbing of it. Since mine has no HIN on it, I had to submit pictures to Game and Fish, who will then assign a HIN. My question: How should I permanently inscribe this HIN on the outside of the transom? Do any of you have any experience with this?
