Hello, I am new to the site. I have a Hellion also. Mine is original, Dad bought new. It has a decal in the motor well with capacity, motor size, etc...There was a 6 digit alpha/numeric number on it that I believe was the hull number. It never had a title because of its small size, and here in the state of Ohio, I was able to register it under the same state registration number that Dad had on it 40 years ago. Had to sweet talk the lady at the Ohio title office, but they were able to do it. Other than the Little decal, there are no other numbers on the boat that I know of, and I have been over every square inch of this boat. Are you in Ohio?
