8.3.7 Anodes
General points
- The sacrificial anodes protect the boat's metal components from electrolysis.
- A sacrificial anode is a consumable part that protects submerged metal parts by its dissolution (oxidation). The anodes
used are made of a metal that is more readily reductive than the metal they are protecting.
- On a new boat, all the underwater metallic components try to be at the same electric potential, which leads to the rapid
deterioration of the anodes in the first few weeks in the water.
- You can put several anodes on the hull.
Maintenance
- At least 2 times a year, check the corrosion on all of the anodes. Change the anode if necessary (Before it lost 50% of
its weight).
- Use the appropriate anodes for the cruising area: fresh water/magnesium anodes; Sea water/zinc anodes.
- If the motor mountings are raised, the anodes are out of the water: in this case the anodes can no longer protect the
sterndrive: take note of the skipper's recommendations.
- When the boat is kept in a dry dock, a light deposit of dust will settle on the anodes: Before returning the boat into the
water, clean the anodes.
Cleaning anodes
- Use sandpaper. Do not use metal brushes or steel tools to clean the boat, it may damage the galvanic protection.
Replacing the anodes
- The anodes are fastened with screws and nuts. First, remove the screws and nuts that hold the anode, then clean the
contact surface. Press the new anode to obtain a good electrical contact.
- Never cover the anodes in antifoul.
- During the first few weeks that the boat is in
the water, check the anodes and if necessary
replace them: they erode very rapidly during this
period.
