All these props (first with #5, then with #6) had nasty grease pumped
out of 'em-and fresh grease pumped in every 100 hrs (usually 6-8
weeks). Never had corrosion issues, had very very very very few grease
leaks at the hub.

Hey TC, when should we be overhauling our props?

Mine is getting up there in years/time, but my A&P believes that if it ain't
leaking, and everything is functioning properly, there is no reason to mess
with it.

True?

You need to find a "friendly" prop shop that will split the hub, do a
very general inspection-looking for corrosion or other very bad
things-replace all the seals and put it back together with a re-seal
sign-off. I would recommend every 6-8 years.

The trick is not to let anything expensive get corroded/worn beyond
limits. Prop overhaul is pretty much like engine overhaul when you're
flying Pt 91. You definitely don't need to follow the mfg's TBO, but
you can't ignore it (engine or prop) completely.
