Martyr Yamaha Transom Handle Anode – Magnesium | Freshwater (CM6G54525101M)
The Martyr CM6G54525101M is a magnesium sacrificial anode designed as a direct OEM-equivalent replacement for the transom handle (clamp bracket) anode on Yamaha outboard motors used in freshwater environments. It replaces Yamaha OEM part 6G5-45251-01 and provides reliable galvanic corrosion protection at the transom handle position on the motor.
Magnesium is the correct anode material for freshwater use — it is more electrochemically active than aluminum or zinc in low-conductivity freshwater, providing effective galvanic protection where other anode materials may be too passive. Martyr Anodes are manufactured to OEM-equivalent specifications, making this a trusted replacement for the factory anode.
Key Features
- Magnesium construction — correct material for freshwater use
- Direct replacement for Yamaha OEM part 6G5-45251-01
- OEM-quality Martyr Anodes construction
- Protects the transom handle (clamp bracket) position on the Yamaha outboard in freshwater
Compatible Applications
- Yamaha outboard motors — transom handle anode position, freshwater use
- Replaces Yamaha OEM part number 6G5-45251-01
- Lakes, rivers, and other freshwater environments
Parts Desk Insights
This is the freshwater magnesium variant of the Yamaha transom handle anode — the right choice for Yamaha outboard owners who operate in freshwater lakes and rivers. The transom handle anode protects the clamp bracket area where the outboard mounts to the transom, a position that is constantly submerged and exposed to galvanic corrosion. Magnesium is essential for freshwater use; aluminum or zinc anodes in freshwater may not corrode fast enough to provide adequate galvanic protection, leaving the motor underprotected. For the same anode position in saltwater or brackish water, see the aluminum version: Martyr CM6G54525101A Yamaha Transom Handle Anode, Aluminum. For the zinc version, see the Martyr CM6G54525101Z Yamaha Transom Handle Anode, Zinc. For other Yamaha individual anodes, see the Martyr CM6AW4525100A Yamaha Trim Tab Anode, Aluminum, Martyr CM6E04525111A Yamaha Small Block Trim Tab Anode, Aluminum, Martyr CM61A4537100A Yamaha Skeg Anode, Aluminum, Martyr CM6644537101A Yamaha Skeg Anode, Aluminum, and Martyr CM68V1132501A Yamaha Internal Anode, Aluminum.
