With all zincs, including the MaxProp: Smack them with a hammer for
better contact, then torque down again. Ours all decay from the outside
mostly.

Here is a trick I read about, but haven't tried for MaxProp zincs, but I do
recognize the symptom:

These zincs are a cone shaped piece of metal that screws to the face of the
prop with three screws in each of the corners. The problem is that there is
very little metal surrounding those screws, so after a bit of wastage, the
whole thing falls off. But if you paint around the screw holes with
fingernail polish, that will protect the metal that holds it together and it
will last much longer.

There is plenty of surface contact with the prop face assure a good
electrical continuity. The same is true for the ID of prop shaft zincs.

Hi,

I believe it was in Nigel Calder that I read -

better propshaft zincs have an inner band that is bonded to the prop
shaft, eliminating loose connections to the shaft after the zinc has
been partially eaten.

Does anyone know of a good source for these higher quality prop-zincs?

Thanks,

Mike.
