Polipodio 61A-45371-00 6L9-45371-00 Yamaha Mariner Directional Trim Tab Anode Ø100 mm – Zinc / Aluminium
The Polipodio YA041 and YA041AL are directional trim tab sacrificial anodes for compatible Yamaha and Mariner outboard engines. The anodes feature a circular mounting plate with an integrated directional fin and are available in zinc and aluminium.
The circular plate measures Ø100 mm, with an overall length of 110 mm including the fin. The side profile indicates a 70 mm vertical fin dimension and a 20 mm lower mounting dimension. The central threaded mounting connection is M10 × 1.25.
These anodes provide sacrificial galvanic corrosion protection for electrically connected underwater metallic components. The directional fin configuration also allows the component to serve as a trim tab in the corresponding outboard installation.

Compatibility and Maintenance
Designed for compatible Yamaha and Mariner outboard engines using this directional trim tab configuration. Select the appropriate material and check the original reference, Ø100 mm plate, fin geometry and M10 × 1.25 mounting thread against the existing component.
Inspect the sacrificial anode during routine outboard maintenance and replace it when significantly depleted or damaged. Follow the engine manufacturer's instructions when installing or adjusting the directional trim tab.
