The only hub that will fit an XS is the “Fat” hub, since the prop shaft is larger than the standard hub and has more splines. I agree with Phil that, given its all metal construction, that you will do significant damage if you tear it up—however, I guess Im conservative. I carry a spare hub with my spare prop in my boat. I think I paid about $150 for the spare, if that helps. Best regards, Mike Whitten/Germantown, TN
