Is there signs of internal corrosion? Is your friend interested in potentially having a smoother less vibration prone operation?

I usually lean towards replacing the mount with new myself, these questions might help make that decision.

Agreed and on top of that would be which mount is it? Cessna made several improvements over the years - I would not even mess with some of the earlier ones - the ones with out the two side vertical tubes.

This is a good read on the Cessna engine mounts (not very long), I'm not pitching the seaplanes west mount (but that is what I went with, but I upgraded to a Pponk and 3 blade prop and I had the older engine mount with out the vertical tubes ) - just providing it for some info on the older cessna mounts.
