Bought a brand new 2012 Yamaha FX SHO. While riding, quite a bit of water would get inside. Dealer didn't believe me at first, until they put in on the water. They kept the ski at least 3 weeks without finding the cause, during which time I was very patient and cooperated with them. Eventually they gave me another one, which I own now. A couple of weeks later, the service advisor called me and said they had found the problem. A faulty gasket (where the top attaches to the hull). Found it by filling it with water completely (had filled it with water before but not all the way). It was a very frustrating experience, I spent about 10 hours on the water trying to troubleshoot the darn thing...
