But the point was preventing growth. Do you find that the zinc in close
proximity to the hub of the prop prevents or reduces growth on the hub? I
do.

That's how the thread got started. If we're away from the boat for two
weeks while the water's warm, I've learned to cycle forward-reverse
gently a few times to make sure the growth gets knocked away from the
(feathering) blades.

I literally have tried everything except no zinc.
