One more quick thought. If you know the approximate surface area of the
prop and the weight of the zinc lost in say 2 months, it is fairly easy
to figure out whether that is in the normal range. Let us know and we'll
try to tell you.

Yet another thought.
If your larger zincs really do look
"new" (i.e., they are shiny) then they
are probably active. An inactive zinc
usually looks dark and tends to acquire
a film characteristic of submerged matter.
