Outdrive Shimming Required?

Anyone know of external/ performance indications that the DP outdrive needs to be shimmed, or is it just routine to check shimming at 1000hrs?

Hey Sean,
By no means I'm I an expert on this subject but personally I would never ever crack a case open to check shim clearences if its working good.
I've rebuilt a few OD and re sealed a few more and I only check end play and shim clearences when replaceing bearings and other internal metal parts.
When I re seal an OD I put all shims in exactly the same place they came from and theirs never been a problem.
If you want more info get on the Hull Truth web site

I'm no expert either, but that sounds like good advice to me.

Thanks for the advice Old Blue and Royal Hook.
