I see quite a few people running the X gears instead of the XR gears. I have a few friends that are running them now with no problems at all and have checked them yearly. That's just another option you have.

X/XZ upper is the same.
Bravo 1 x uses the x upper, std bravo lower
Bravo 1 XZ uses x upper, xr lower.
I rebuilt my its xr drives last year with x upper gears.

Found a set of XR uppers today that I now realize will work with the XZ lowers and clutch I bought. Overpaid, but as they say, pay to play. Would much rather be boating than waiting on gears at the mercy of Mercury! 😎

Good deal! I would of done the same thing, buys you time on the water until the others are available
