The Martyr Rudder/Trim Tab Anode – Aluminum is a sacrificial marine anode designed to help protect your boats rudder or trim tab from corrosion caused by stray current and galvanic activity. Built for saltwater and brackish water use, this aluminum rudder anode delivers dependable cathodic protection while offering longer-lasting performance than traditional zinc in many marine environments. Its aluminum finish matches the alloy construction used throughout the product line.

Key Features

• Corrosion Protection: Helps shield rudders and trim tabs from electrolysis and galvanic corrosion in harsh marine conditions.
• Aluminum Alloy Construction: High-purity aluminum alloy is designed for use in salt and brackish water applications.
• Secure Mounting Hardware: Includes stainless steel fastening hardware for reliable installation and retention.

Martyr anodes are widely chosen by boat owners and marine technicians who want a dependable, cost-effective way to protect underwater metal components. This rudder and trim tab anode mounts directly to the application point and is sold in two halves for straightforward installation. Whether you run a fishing boat, cruiser, or other saltwater vessel, Martyr helps reduce corrosion-related wear and extend the service life of critical hardware.

Available in multiple diameters, including compact and larger-size options, this aluminum marine anode is a practical maintenance item for routine boat care. For best results, use aluminum anodes in salt or brackish water; freshwater applications typically require magnesium instead.
