Martyr Yamaha Small Block Trim Tab Anode – Aluminum | Saltwater & Brackish (CM6E04525111A)
The Martyr CM6E04525111A is an aluminum sacrificial anode designed as a direct OEM-equivalent replacement for the trim tab anode on smaller Yamaha outboard motors used in saltwater and brackish water environments. It replaces Yamaha OEM part 6E0-45251-11 and provides reliable galvanic corrosion protection at the trim tab position on the lower unit.
Aluminum is the correct anode material for saltwater and brackish water use, where it outperforms zinc in electrochemical activity and provides more effective galvanic protection. Martyr Anodes are manufactured to OEM-equivalent specifications, making this a trusted replacement for the factory anode.

Parts Desk Insights
This is a single aluminum trim tab anode for smaller Yamaha outboards — the right choice when only the trim tab position needs replacement and the other lower unit anodes are still serviceable. The “small block” designation refers to the compact anode size used on smaller Yamaha outboard models, as opposed to the larger trim tab anodes used on bigger F-series motors. Aluminum is the preferred material for saltwater and brackish water use, providing better galvanic protection than zinc in marine environments. If you operate in freshwater, a magnesium anode would be required instead. Verify your specific Yamaha model’s compatibility with OEM part 6E0-45251-11 before ordering.
