Easy out of the hole if you have big power, watch your throttle if you catch air, the re-entries are very hard on the drive. Depending on your horsepower, no matter how careful you are eventually it'll die. If you have a small block, or big block that's non mag or non ho it may last forever for you. 500 hp or better, it's just a matter when not if.

A year or two ago, Mercury had a bad run of upper XR gears that would fail at 25 - 50 hours. There were a couple of threads on it. Other than that, just what was said. I run billet top caps with integrated water cooling and they add strength on the left hand turning drives.
