i had a 14.25 X 14.0 on my 2005 XStar with MCX. i replaced the 13.7 X 17.5 and i could pull stumps out of the water with it. the 14.25 X 14.0 is the way to go if you don't mind losing a little top end. i could have cared less about going over 30 mph. i wanted a tractor that responded well at wakeboarding speeds and that prop at eric at oj's sugestion gave it to me. talk to eric at oj before you do anything however. he will set you straight then do exactly what he tells you to do and yo will never regret it.
