Anode Replacement
Without fail, the corrosion of a boat’s anode is inevitable. A sacrificial anode is , as the name suggests, a sacrificial metal that will succumb to galvanic corrosion before other parts of the boat. If maintained correctly, the anode will save you a lot of money.
In order to ensure optimal function and to avoid replacing more expensive parts of your boat, regular maintenance of an anode is crucial.
Generally, your anode should be replaced when 50% of the sacrificial anode has been replaced. The anode is normally unable to properly protect your boat when the anode levels drop below 50%.
If the replacement of the anode is left too late, the whole boat becomes susceptible to corrosion-related damage, expenses and risk. The regular maintenance of your sacrificial anode can help to keep your boat performing at its best. As a result, regular checks of your anode should be performed.
There are many factors that can lead to a faster depletion of your anode including:
Faulty wiring
Salinity
Stray electrical current
Water current flow
Water temperature.
