Sierra Zinc Anode Marine Corrosion Protection

Sierra zinc anodes provide marine corrosion protection for boats, outboard motors, sterndrives, inboard engines, trim tabs, and other submerged metal components. Often called sacrificial anodes, galvanic anodes, or zincs, they are made to corrode in place of the more valuable metal parts they protect.

Key Features:

• Zinc construction supplies sacrificial galvanic protection against electrolysis and galvanic corrosion
• Helps protect underwater metals such as aluminum, bronze, and stainless steel hardware from corrosion damage
• Intended for saltwater and brackish water use
• Available in multiple styles and configurations to suit different engines, drives, and hull applications
• Replaceable design lets you renew protection as the anode wears

Check your anodes regularly and replace them once they have eroded significantly. This helps keep corrosion protection effective and reduces the risk of costly damage to your marine drive and engine components. Sierra is a well-known marine parts brand, and its anodes are a dependable choice for routine maintenance. Select the correct variant for your application from the options on this page.
