Thanks Capt. I meant the supplementary zincs that protect the hull. Outdrive
zincs usually are only big enough to protect the drive.

I put mine on my outdrive, as I wish to protect the lower unit. You
can't have too many zincs.

Just taking a little survey. Where are your anodes? There seem to be two
schools of thought:

Put them on the underside of the hull. This is the only part that is
continuously wet, and rate of water passage increases corrosion rates.

Put them on the transom. Boats spend much more time in displacement mode
and
anything under the hull will affect planing performance.

Also, anyone using impressed current? Then the question becomes: Where
is
your anode and reference half cell?

Duckworth puts them on the transom as standard. Calif Bill has his on
the
transom. Any comments? Thanks.
