Martyr Anode – BRP / OMC / Johnson / Evinrude Outboard, Aluminum | Saltwater & Brackish (CM393023A)
The Martyr CM393023A is an aluminum sacrificial anode designed as a direct OEM-equivalent replacement for BRP, OMC, Johnson, and Evinrude outboard motors used in saltwater and brackish water environments. It replaces OEM part number 393023 and provides reliable galvanic corrosion protection at the corresponding anode 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.
Key Features
- Aluminum construction — correct material for saltwater and brackish water use
- Direct replacement for OEM part number 393023
- OEM-quality Martyr Anodes construction
- Reliable galvanic protection for BRP/OMC/Johnson/Evinrude outboard lower units

Parts Desk Insights
This is a single aluminum anode — the right choice when only the 393023 position needs replacement and the other lower unit anodes are still serviceable. 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. For other BRP/OMC/Johnson/Evinrude individual anodes, see the Martyr 123009 Anode, Martyr 397768 Anode, Martyr 398331 Anode, Martyr 5007089 Anode, Martyr 5007089 Anode (alternate), Martyr 984513 Anode, Martyr 984547 Anode, and Martyr 984547 Anode (alternate).
