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.
