14.2.1 Periodic check of external anodes
This operation is usually carried out when the yacht is in a dry shore. It
may be done in water with help of a diver.
If the underwater anodes have not been checked recently and a haul-out
is not planned, you should hire a diver to check and replace anodes.
14.2.2 Replacing the external anodes
The sacrifical anodes are fastened to the yacht in several positions on the
hull. Before installing a new anode, clean the area under the old anode
with a wire brush or fine sandpaper. Remove all residuals left by the
anode. Install the new anode and put some silicone on each of the screw
ends that fasten the anodes. This will make replacement easier when
they are worn out.
Do not fasten anodes with glue or other adhesives that may hinder their
removal, and will actually prevent the anodes from doing their job.
Do not paint the anodes.
There are internal anodes in the engines, generator, and other equipment
that uses seawater as a cooling liquid. Check and replace these anodes
according to the maintenance schedule in the Manufacturer’s manuals
for the specific equipment.

WARNING
Before cleaning the bottom or checking the underwater anodes while
the yacht is in the water, disconnect engines and generator so they
cannot be started accidentally. Serious injury or even the diver death
could result. Remove the ignition keys.
NOTICES
Failure to replace the anodes causes corrosion on other metal parts.
NOTICES
It is necessary to check the wear (waste) of the anodes and to replace
them as soon as the wear exceeds the 50% of their original size.
