Boats are kind of pains in the butt when it comes to selling them, or at least requires a lot of information. I sold mine recently and had to give the buyer, on the bill of sale, the make/model, hull ID, motor make, hp, and serial number, and trailer make and serial number. The bill of sale also had to have my address on it, and had to be notarized. Plus I had to give him my current registeration, to show it matched my address on the bill of sale and that I had the legal right to sell the boat. All this according to the Shelby County License office.
