The transoms are the strongest in the industry with the vacuum process. I would have it checked out at a dealer if possible, just for your peace of mind. Realistically, if you dont know how often it was used, it would be like any other buying situation, a buyers choice kind of deal. I personally do not think there would be much concern…and you could check into the transferrable lifetime warranty on this boat as well.
