Engineered Marine Products 93-04629 Aluminum Sacrificial Anode

The Engineered Marine Products 93-04629 is an aluminum anode designed to provide reliable galvanic corrosion protection for marine applications. Aluminum anodes are a popular choice for boaters operating in brackish or salt water environments, offering superior electrochemical performance compared to zinc anodes while remaining environmentally compliant in many regions.

Sacrificial anodes work by corroding in place of more valuable metal components on your vessel — such as outboard motors, stern drives, trim tabs, rudders, and underwater hardware — extending their service life and protecting your investment. Aluminum alloy anodes are highly effective across a broad range of water salinity levels, making them a versatile solution for mixed-use or coastal boating.

Key Features:

• Material: High-purity aluminum alloy for maximum sacrificial protection
• Effective in salt, brackish, and fresh water environments
• Helps prevent galvanic and electrolytic corrosion on underwater metal components
• Environmentally friendly alternative to zinc anodes in regulated areas
• Direct replacement anode for compatible marine applications
• Manufactured by Engineered Marine Products to OEM-quality standards

Replace your marine anodes regularly — typically each boating season or whenever the anode has been depleted by approximately 50% — to ensure continuous protection of your underwater components.
