Hi all,

I have a 9.9 Gamefisher outboard. It's in pretty good shape other than a
broken drive shaft so I'd like to repair it. I've dis-assembled the lower
end to find a shim broken up in pieces. Seems this may have caused the gears
to lock and break the shaft. I'm not certain, though. The strage thing is
the shaft had score marks from rubbing against the base plate of the
impeller housing. Maybe it was bent or otherwise damaged.

Anyway, this shim has been cleaned out of the gear case. But I need to know
a couple things:
1) How do you properly shim the lower unit gears? What special tools are
required?
2) There are some bits of shim that welded themselves to the end of the prop
shaft spline. I'm planning to use a lathe to clean this area, but then will
need to make up for the space with shim adjustments. Is this correct or is a
new prop shaft a must have? There is no significant damage to the prop
shaft.

Thanks for any help.

Greg
