I agree these are not anodes but grounding plates. If you look on inside something is earthed/grounded to these plates.

this grounding plate is made from sintered bronze and can be used in a DC bounding but is not a anode.
It is normaly used for the SSB radio installation.

I agree that looks like an SSB ground plate.  My 418(#120) has a zinc in a similar place from the factory,  is this also a grounding plate or an engine zinc?

David,
This is the zinc -anode to protect against elektrolyse.
In our boat connected by a yellow- green wire (bounding) to Keel,watertanks ,fueltank , gen frame
 Earth of Charger-inverter And DC neg buss.
We disconnect it from the Allu ruddershaft (original connected by the Hanse yard )like Jefa adviced .
