if there is anything fishy, or if you think the boat may have been registered in SC, call the DNR title office and have them run the numbers, make sure there is no old bagage tied to them. On the motor, have a bill of sale, take pictures of the serial number tag on the transom bracket, and of the welch plug on the power head, make sure they match, print out the pics, take them to the title office with you. I've found with the Ft. Johnson office down here, if you have all your paper work in order, have pics documenting the id of the motor, then it usually goes smooth. Don't try to pull any thing tricky, if in doubt, tell them the truth. A relative of mine is a DNR investigator, he's one of the ones that checks up on the questionable titiling, he's told me some stories about some of the stupid things people have tried to pull. He told me, if they are upfront and honest about it, he will do what he can to help, if they lie to him, they are going to get cited, fined, and still not have a clear title
