Boat anodes are an essential part of the boat maintenance cycle as they protect underwater metals from galvanic corrosion. Also known as sacrificial anodes.
We recommend replacing anodes when they are half eroded or dissolved, which is typically once a year. The speed in which anodes dissolve depends on a range of factors including usage, location (of your boat), water temperature and the quality of the anode itself. For example, MG Duff's zinc anodes have a high zinc content, ensuring they provide maximum protection for a longer period of time.
Without anodes, underwater metals are at risk of galvanic corrosion - which could in turn lead to a hefty repair bill.
