Osculati 43.270.01 – Yamaha 6J9-45371-01 Aluminium Rightward Bend Fin Anode for 100–220 HP Outboards
The Osculati 43.270.01 aluminium fin anode is a precision-engineered trim tab anode designed for Yamaha 100–220 HP outboard engines. Replacing OEM part 6J9-45371-01, this component combines hydrodynamic steering correction with electrochemical corrosion protection.
Its rightward bend compensates for engine torque and propeller thrust, stabilizing the boat's tracking. At the same time, the high-efficiency aluminium alloy provides excellent galvanic protection for submerged lower unit components, especially in saltwater and brackish environments.
Main Features:
- Material: Marine-grade aluminium alloy
- Replaces Yamaha OEM: 6J9-45371-01
- Function: Fin anode with rightward bend for torque compensation
- Application: Outboard motor trim tab for 100–220 HP
- Diameter: 100 mm
- Mounting: Central bolt-on (OEM-compliant)
- Ideal for saltwater and brackish water use
- Lighter and more eco-friendly than zinc alternatives
