Rode on my friends 04 X-Star this weekend and it made me feel pretty good about my boat. PP was set on 20 mph. When I drove and he was riding, the boat would go to 25, then drop down to 15, then back to 25. He couldn't understand that I wasn't the one doing it. His boat has had it's fair share of issues as well, but I think has have been a lot more major than mine.
