Sacrificial Anodes & Replacement Zincs

Marine Grade Sacrificial Anodes

Protect Your Boat with High-Quality Boat Zincs

Fisheries Supply provides marine grade sacrificial anodes, also known as zincs or galvanic anodes, designed to protect your boat from corrosion. These highly active metals are essential for preventing the corrosion of less active materials such as propellers, and other underwater components. Our extensive inventory includes a full range of boat zincs designed for both saltwater and freshwater use, ensuring your boat remains protected in any marine environment, including brackish water.
Marine zincs, along with aluminum anodes and magnesium anodes, are essential for protecting underwater metal structures, as they prevent galvanic corrosion that occurs when dissimilar metals are in contact.

Types of Zinc Anodes for Boats

We offer a variety of zincs for boats to meet your specific needs:

• Shaft Anodes
• Outboard Anodes
• Trim Tab Anodes
• Pencil Anodes
• Hull and Strap Configurations

Why Choose Zinc Anodes?

Zinc boat anodes are particularly effective in saltwater environments due to their ability to corrode gradually, continuously exposing fresh zinc. This process ensures long-lasting protection for your boat's metal parts. Regular inspection of these anodes is crucial to determine the appropriate replacement cycles. Ideally, marine zinc anodes should be replaced when about half of the anode has been lost to corrosion, typically not more frequently than annually.

Expert Advice from Our Representatives

We are here to help you select the right zinc anodes for your boat's underwater metal components.

When choosing anodes, consider factors such as:

• Material Compatibility: Ensuring the anode material matches the metals on your boat.
• Positioning: Proper placement to maximize water flow contact. Anodes must be fully submerged.
• Desired Protection Levels: Tailoring the anode size and type to your specific needs.
• Avoid painting anodes as this can hinder their conductivity and effectiveness.
• Ensure good electrical contact by cleaning the surface where the anode will be attached.

At Fisheries Supply, we stock zinc anodes from trusted brands known for their quality and durability. Our online inventory makes it easy to find the right anodes to protect your boat from electrolysis damage while on the water.
