I sold a sportmaster gearcase to a guy last year. He calls me a month later and says he just put it on that day. He said he checked it before running it and it was full of water. Now, I just put in new gearlube about an hour before I shipped it so I know he was BS'n me. I just said "fine, send it back for a full refund" He said he wanted $600. I just told him No, that's OK. I'll just send you a full refund. I never heard from him again!
