I sold my boat three weeks ago. The boat was used once two summers ago and not at all this summer. Two summers ago there were problems with it, so I had a marina check it out and they said I need a new water pump and a tune up. I didnt have the work done, but I told the buyer all of this information. Since the inspection at the marina, I havent run the boat at all. The buyer checked out the boat with his friend who was a mechanic. The boats blue book value is 4000, and I sold it to him for 1500, making sure he new that there were issues with the boat. He called me the other day to tell me that the engine block was cracked and he wanted to make restitution. Do I legally owe him anything? The boat was sold in New Hampshire.
