Osculati 43.822.17 – Mercury 822157-C2 Magnesium Fin Anode 25/50 HP 2/4-Stroke
The Osculati 43.822.17 magnesium fin anode is a highly reactive corrosion protection component specifically designed for Mercury outboards ranging from 25 to 50 HP. Compatible with both 2-stroke and 4-stroke models, this anode replaces OEM reference 822157-C2. It is mounted beneath the anti-ventilation plate and serves a dual function: providing sacrificial protection in low-conductivity freshwater environments, and correcting steering torque via its integrated hydrodynamic fin profile.
Key Features:
- OEM reference: Mercury 822157-C2
- Material: High-purity magnesium alloy
- Compatibility: Mercury 25–50 HP (2-stroke and 4-stroke)
- Application: Freshwater protection for lower unit and steering system
- Dual function: Corrosion resistance + propeller torque compensation
- Installation: Mounts under anti-ventilation plate (torque tab location)
- Highly reactive material suited for low-conductivity water

Magnesium anodes are essential for effective protection in freshwater where other materials are too passive. The Osculati 43.822.17 ensures your Mercury outboard’s critical components remain shielded from internal corrosion, while also improving handling through torque correction. Lightweight, powerful, and easy to install, it’s the ideal choice for lake and river operation.
