Martyr Transom Bar Anode – Nissan / Tohatsu Outboard, Zinc | Saltwater (CM3C7602181A0Z)
The Martyr CM3C7602181A0Z is a zinc sacrificial transom bar anode designed as a direct OEM-equivalent replacement for Nissan and Tohatsu outboard motors used in saltwater environments. The transom bar anode mounts across the transom bracket of the outboard and provides galvanic corrosion protection at one of the most exposed positions on the motor.
Zinc is the standard anode material for saltwater use, providing reliable galvanic protection in the higher conductivity of marine water. Martyr Anodes are manufactured to OEM-equivalent specifications, making this a trusted replacement for the factory anode.
Key Features
- Zinc construction — correct material for saltwater use
- Transom bar anode — protects the outboard’s transom bracket position
- Direct OEM-equivalent replacement for Nissan and Tohatsu outboards
- OEM-quality Martyr Anodes construction
- Reliable galvanic protection at one of the most exposed positions on the motor
Compatible Applications
- Nissan outboard motors — transom bar anode position, saltwater use
- Tohatsu outboard motors — transom bar anode position, saltwater use
Parts Desk Insights
The transom bar anode is one of the most important anode positions on a Nissan or Tohatsu outboard — it sits directly on the transom bracket, which is constantly submerged and highly exposed to galvanic corrosion in saltwater. This is the right choice when the transom bar anode needs replacement and the other motor anodes are still serviceable. Zinc is the standard choice for saltwater use. If you operate in freshwater, a magnesium anode would be required instead; if you operate in brackish water, aluminum is preferred. Verify your specific Tohatsu or Nissan model’s compatibility with part number CM3C7602181A0Z (OEM ref. 3C7-60218-1) before ordering.
