Martyr Volvo Penta SX Gimbal Plate Anode – Aluminum | Saltwater & Brackish (CM3854130A)
The Martyr CM3854130A is an aluminum sacrificial anode designed as a direct OEM-equivalent replacement for the gimbal plate anode on Volvo Penta SX stern drives used in saltwater and brackish water environments. It replaces Volvo Penta OEM part 3854130 and provides reliable galvanic corrosion protection at the gimbal housing position on the drive.
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 gimbal plate anode — the right choice when only the gimbal plate position needs replacement and the other SX drive anodes are still serviceable. The gimbal plate anode sits at the transom interface of the SX drive and is one of the primary corrosion protection points on the drive. 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 the zinc version of this same anode, see the Martyr CM3854130Z Volvo Penta SX Gimbal Plate Anode, Zinc and the Volvo Penta SX Gimbal Plate Zinc Anode CMT-3854130Z. For the SX transom plate anode, see the Volvo Penta SX Transom Plate Zinc Anode CMT-3855411Z.
