Question Survey- Bravo x drive reliability??

Cobra Marty had a great thread last year on Bravo's failures and factors. Many of us now have or are considering x drives (x,xz or xr) in the future. It would be great to hear from those who have accumulated some hours on these drives and learn how they are doing. If I remember right there were some reports of gimbal hsg failures and also short lives when pushing a heavy boat. I believe Goodfella @ Dollar even reported the xz upper gears holding up better in the factory racers. For those of you with some hours, please report what you can:

Which drive?
still alive?
hrs on drives?
hp/tq?
single/twin/triple?
prop pitch/gear ratio?
showered?
length/wt of boat?
v or cat?
internal inspections and results?
lube used?
gentle/ average or madman on the sticks?
frequent air time?

Thanks for your help!

XR drives
no failures, yet or possibly .........
Triple 700(s) supercharged (Whipples) 500 EFI's
showered
Vee bottom, step, notch, extension box
boat weight app. 13,500 pounds
1.36 ratio
31 pitch Hydromotive 5 blades
length 43'
gentle on the throttles
app. 100 hours run time
Merc. green gear lube
Taken off and lubed at 50 hours, everything OK, and again at 100 hours all OK except Pinion seal shot on Port outside drive (Apparently common problem on XR drives) When this goes, it leaks drive fluid into the bellows and then the bilge.
Air time, some, most trips are lengthy to Bahamas or Keys.

Sorry Cattitude, I don't have anything to add - only Bravo Ones. But at least I can get your worthy thread back to the top.
