Welcome Aboard Scott!!
Yes, you are looking for a Hull Identification Number (HIN):
They are located on the starboard side of the transom, and were mandatory in the US on boats manufactured after 1972.
Where are you located, generally speaking (e.g. country and state where the boat is going to be registered)? Have you looked into registering a power boat in your area and what the requirements are for title and Bill of Sale?
[update]: Ya, I just noticed 'Scott Illinois', either that is a unique last name or I'm an idiot and you already answered part of my question.
