Put a donut zinc between the strut and the prop.


Uhhh, We HAVE had a zinc on the shaft and the MaxProp's hub as well.
Both get half eaten each year. Before the MaxProp & its zinc, we lost
the same half of the shaft zinc.

Well, of course the zinc gets eaten. That it gets assymetrically eaten
indicates a directional electrolysis current or whatever at your slip or
mooring. But that's odd too. Does your prop stop in the same position
every time?

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.
