Martyr CMP-06 Trim Tab Anode
Martyr CMP-06 is a rudder/trim tab disc anode crafted from an aluminum alloy suitable for salt and brackish water. It provides protection up to 50% longer than traditional zinc anodes and eliminates cadmium, offering an environmentally friendly option. The design supports reliable performance with standard trim tab hardware and offers corrosion resistance where aluminum hulls are concerned.
Lectrotab Alloy Sacrificial Anode
Lectrotab’s sacrificial anode features a 2-13/16″ diameter and 0.5″ height, made from superior aluminum/indium alloy for enhanced protection. Aluminum anodes generally outperform zinc in longevity and are safe across water types, providing dependable protection for trim tabs and rudders in mixed environments.
Bstinay Aluminum Trim Tab Anode (RC Model)
Bstinay offers a compact trim tab anode designed for RC boat applications, with dimensions of 38×31.5×11.5 mm. Constructed from metal, the unit emphasizes sturdy performance and a clean, modern appearance. Verify compatibility with your hull and tab size before purchasing to ensure a precise fit.
Quicksilver Aluminum Trim Tab Anode
Quicksilver’s trim tab anode is designed to supplement Mercury/Mariner systems, providing corrosion protection and hydrodynamic trim force to aid steering. The unit aligns with OEM specifications and is easy to replace with common tools; ensure propeller clearance is checked prior to operation for optimal results.
Martyr CMR03AL Aluminum Anode
This Martyr CMR03AL aluminum anode is pressure diecast and manufactured under ISO 9001 standards. It emphasizes high-quality alloy composition with minimal impurities to maximize protection. Martyr offers three alloy options—zinc for saltwater, aluminum for brackish water, and magnesium for freshwater—allowing tailored corrosion resistance based on your water type.
US Marine R2 Aluminum Anode
US Marine’s R2 Aluminum Rudder and Trim Tab Anode replaces multiple models (including Martyr CMR02AL) with a 2 13/16″ diameter. Designed for salt and brackish water, these aluminum anodes provide durable protection and broad compatibility with common trim tab systems.
Buying Guide
Key purchase considerations include water type, compatibility, and installation practicality. If you operate mostly in saltwater or mixed environments, prioritize aluminum or indium-aluminum alloy anodes for longevity and corrosion resistance. For brackish or freshwater use, selecting an alloy suited to those conditions helps maximize protection and reduce maintenance. Consider the trim tab’s material, mounting pattern, and whether the anode is designed to replace an existing model to ensure a straightforward swap. Replacement ease, availability of OEM-spec parts, and warranty support are additional factors that influence long-term performance. Compare weight, size, and corrosion resistance across brands to find the best fit for your aluminum boat’s trim tab system.
