🔌 Function

  

The anode sacrifices itself to help protect nearby underwater metal components from galvanic corrosion. Correct anode material and condition are important for protecting gearcases, drives and other submerged metal parts in saltwater use.

  

Common signs of failure:

  

• Anode heavily worn or missing

• White, chalky or crumbling anode surface

• Corrosion appearing on drive or gearcase components

• Anode no longer securely attached

• Anode more than half consumed

• Incorrect anode material for water type

  

📦 Condition

  

• Genuine Quicksilver part

• Brand new

• Supplied in original or equivalent packaging
