To start from the begining.. 6 months ago I bought a 08 Cajun Speacial. It had a 04 Yahama 115 outboard motor. Now I dont know much about boats and bought this one from a friend. I took it out a few times and never had any problems. Yesterday I sold the boat for financial Reasons. The man came to my house and looked over the boat. He started it up and it ran fine. He didn't want to take it out on the water but wanted to buy it. Now today I get a call and he says the motor is messed up. Says he took it to his friend machanic and 2 cylinders are messed up. This is not something we were aware of. We had never had any issues. Now he wants his money back or he says he will sue me. The bill of sale has in bold capital letters AS IS NO WARRANTY. I do feel bad and want to help him somehow but I sold the boat because we needed the money. My question is can he sue me over this and win? We had no knowledge of anything being wrong. When he was at our house we told him we didnt know how many hours were on the motor and had never had any problems with it...
