I just recently sold a 2001 Seadoo RX. The jet ski ran fine when I took it to the lake. They buyer came to my house and we hooked it up to the hose and it ran and started up fine. The next day he called me back saying the jet ski will not run and will not start and he wants to bring it back and get his money back. I do have a bill of sale that states he bought the jet ski "as is" with no warranty. I told him I would not take it back as it started fine when he took it from my house and he is now threatning a law suit on me. I'm in the state of Texas. Can someone tell me if i'm responsible for taking it back.
