Putting the prop on my XR for the first time and noticed the difference from a standard bravo, no locking washed. What is the order of installation?
1- Hub
2- prop
3- locking nut
Any washers?

there should be a couple of washers between the prop and the nut, the one closest to the nut looks a little bent. If you don't have them, its no big deal, especially if you have a lock nut. Everyone does it a little differently. Just tighten down that bad boy and enjoy the waves.
