I can imagine that racers have this issue even more with the constant changes in throttle position during their events. I also have very bad gout severe arthritis that has effected my throttle hand tremendously. That is why I was very excited to find the EZ Throttle. The installation is pretty easy and straight forward. I installed the EZ Throttle on both skis today in less than 20 minutes with minimal tools. Just remember that the EZ Throttle logo on the throttle faces in, not out and you will will be golden. The EZ Throttle basically slips over your existing finger throttle taking it from approximately two inches to about five inches, which just about mirrors the length of your PWC hand grip.
