Osculati 43.227.77 – Mercury 822777 35/225 HP Fin Anode
The Osculati 43.227.77 is a direct replacement fin anode designed for Mercury outboard motors and sterndrives ranging from 35 to 225 HP. Fully compatible with OEM part number 822777, this anode fits Mercury engines produced from 1995 onward. It protects critical components such as the lower unit, propeller hub, and drive housing from electrolysis and galvanic corrosion.
This fin-type anode not only serves as a sacrificial corrosion barrier, but also contributes to hydrodynamic balance and torque correction in some Mercury engine installations. It is especially critical for boats operating in salt or brackish water environments, where metal components are exposed to continuous electrochemical activity.
Key Features:
- OEM equivalent: Mercury 822777
- Fits Mercury outboards and sterndrives 35–225 HP (1995–present)
- Fin-style anode with hydrodynamic stabilizing effect
- Protects drive and lower unit components from galvanic corrosion
- Recommended for salt and brackish water use
- Simple bolt-on installation to existing engine mount point
