Anode (Pack Of 2) - Sierra Marine Engine Parts - 18-6242-9 (118-6242-9)

Anodes are part of the boat maintenance cycle and protect submerged metals from galvanic corrosion. Which boat anode you should use will depend on the type of water. The many boat anodes on the market today react differently to galvanic corrosion in salt water, brackish water, and freshwater. Aluminum anode alloy is more corrosion resistant and lasts longer than zinc anode alloy. It's suitable for both fresh and saltwater. Aluminum is the only anode that is suited for all uses. Replacement of anodes is required once a year or when they have degenerated or dissolved halfway. The pace at which anodes dissolve is influenced by factors, including usage, location (of your boat), water temperature, and anode quality.

Key Features:

• Aluminum anodes can be used in both salt and brackish water.

• They can be smaller and more compact than their zinc and magnesium equivalents due to their increased electrical capacity
