Sierra 18-6249 Zinc Anode for Mercury Mariner Outboard Transom Bracket

The Sierra 18-6249 is a high-quality zinc anode designed specifically for use on transom mount brackets of Mercury/Mariner and Chrysler/Force outboard engines. This replacement anode provides essential corrosion protection by directing galvanic corrosion away from critical engine components such as shafts, propellers, rudders, and drive parts, sacrificing itself to keep other metal components intact.

• Engineered to meet or exceed OEM specifications
• Compatible with Mercury/Mariner 175 HP, 150 EFI, and 200 EFI outboards (serial number OG303046 and up)
