CAUTIONDo not use pressurised water to clean the sacrificial anodes.
| Component | Maintenance | Notes and precautions |
| Sacrificial anodes | Periodical check |
Frequently check the sacrificial anodes’ wear conditions; replace them when the volume is reduced by more than 50%. |
| Replacement | Loosen the anode fastening nuts, extract the anode and clean the resting surface. Assemble the new anode, tighten the fastening nuts and cover the screw head with silicone. |
Periodical check
This operation must be carried out with yacht on dry shore or with the help of a diver.
Have the outer condition of the sacrificial anodes checked and have them replaced if they show evident signs of corrosion or if their volume is reduced to about 50%.
With the yacht out of the water, it is good practice to use a wire brush, to remove the surface layer of oxide and dirt on the external surface of the anodes.
CAUTIONDo not use pressurised water to clean the sacrificial anodes.
WARNINGTo clean and check the yacht in water: disable the engines and generator start.
CAUTIONCheck the anodes’ wear conditions very frequently (when the yacht is on a dry shore or with the help of a diver) and replace them as soon as wear exceeds 50%.
CAUTIONFailure to replace the anodes causes corrosion on other metal parts.
Assembly/Disassembly
The sacrificial anodes are fastened to the yacht in several positions of the hull. We advise you to clean the seat of the sacrificial anode and cover with silicon the screws ends which fasten the anodes. This will easy the replacement of the anodes when worn out. We advise not to tighten the nuts fastening the anodes with glues or other materials which will hinder their removal.
CAUTIONDo not cover the contact surface between anode and hull with silicone.
