Well then it sounds like my "measurement" was less than accurate to say the least. However, it's almost a guarantee that the backlash is the same as it was before I took the drive apart, given the parts are all the same and I've followed all the torque specs. Oh, while I'm on here I might as well ask, do you guys use gasket sealer on the rubber o-rings & seals? My drive was absolutely covered in it when I took it apart, but the Merc manual instructs to just use a bit of grease... that sure would aid in the next service event, but sealing is so critical, I'll worry without the sticky stuff...

I have used grease (Mercury 2-4-C) several times and no problems with leaks. Much cleaner and easier to sevice compared to using the sticky gorilla snot!:ernaehrung004:

How did you install the brass ring onto the gear to make sure it stays on.

I read somewhere NOT to use any type of sealant on the orings. Just grease them up so they can freely squish out and do their job.

253- I cleaned the inside of the ring with a brass wire brush to remove the factory adhesive then I used a thin layer of this threadlock type stuff... it's not loctite, I can't remember the name. My buddy used it on a stripped exhaust header bolt, it's the same milky red color as shock oil. Really heavy duty stuff. Then I put the assembly in a press and boom. Stuck on there.
