Thanks for all your help D*ick!! I know I would have been searching for weeks to get a 1/10 of the information you gave. I am trying to get a lead and cost on the remaining parts I need to complete this job up in Canada. If I can't find anything I will give Sterndrivespec a call for the parts. 315-623-7642.
Again, I really appreciate you expertise and wiliness to help. I may give you a call once I get everything in hand
Thanks Again
Mike

The new procedure was in Supplement #28 ( I believe). It is the new procedure for the new style, new design upper case. And they look for .009-.015" @ .025 pinion depth, as AT said. Several tools are needed to measure it. The Supplement explains it well.
Hope this helps..

I have a couple of different Bravo repair manuals
from over the years ( 2005 is the latest), and I've never seen anything about checking backlash in the uppers.
The only adjustments they list is the pinion bearing preload,
and the thrust bearing race/ case matching #'s.
It does have proceedures for checking backlash in the lowers
though.
Does Merc have a customer service manual, and a dealer
service manual, with the dealer service manual having
more info in it than the customer service manual does ?
The several that I've had apart are still going strong,
( knock on wood) but, the set up proceedures listed in my
manuals seem very basic, compared to set up proceedures
for a differential in a car, truck, or in our case, a forklift.
I like to check tooth contact, just to see where the
teeth are riding.
I have the upper gears out of my XR's getting cryo treated,
when I reassemble these I'll check backlash and see where they come in at.

Bringing back and old post with good info.
Does anyone know where the "Supplement #28" that describes the procedure for pinion depth and backlash can be found? I cant seem to find it anywhere...
