I have owned 4 different brands of PWC's over the past 10 years and really enjoyed each one. I have since purchased 2 XL800 yamahas (2001) at the 2002 boat show (leftovers) and have nothing but a great results.
I asked the mechanic that had serviced all my PWC's what he recommended. He said that he owned several different brands and raced a couple, and did not own a Yamaha, but if buying one for riding and not working on, he would by the Yamaha. He said he made his living on all the other brands, with the exception of Yamaha. So that is what I bought. They have been great.
