I had mine done at a trophy shop, had them do two, one for the transom, and the other under the gunwhales in case it was stolen/recovered.
2 was under $15.00.

So I can put MY paperwork on an unnumbered boat???
My HIN has been checked once by game and fish, no HIN could be an issue/hassle, insurance likes them on there too.
