The Sierra 18-6155Z is a complete zinc sacrificial anode kit engineered for OMC Cobra sterndrive applications. Sacrificial anodes are a critical component of any marine maintenance routine, protecting valuable underwater metals — including shafts, propellers, rudders, and drive components — from the damaging effects of galvanic corrosion by corroding in their place.
Constructed from high-quality zinc alloy, this kit is optimized for use in saltwater environments where galvanic corrosion risk is greatest. Sierra parts are manufactured to meet or exceed OEM specifications, making this a reliable direct replacement for worn or depleted anodes on your OMC Cobra drive.
