Sierra 118-6028 Zinc Gearcase Anode for OMC and Volvo Penta

The Sierra 118-6028 is a high-quality zinc sacrificial anode designed to protect OMC stern drives and Volvo Penta marine engines from galvanic corrosion. This replacement anode is engineered to meet or exceed OEM specifications, providing reliable corrosion protection for gearcases in saltwater environments.

Key Features:

• Constructed from pure zinc material for optimal saltwater protection
• Direct replacement for OEM part numbers including OMC 984513, 3853818, 3855412 and Volvo Penta 3855411, 384513
• Designed specifically for OMC stern drives and Volvo Penta engine applications
• Manufactured to meet or exceed original equipment specifications
• Also cross-references with GLM 12774 and Evinrude/Johnson 3853818

Sacrificial anodes are essential components that corrode in place of more expensive engine parts, protecting propellers, shafts, rudders, and drive units from damaging electrolysis. Regular inspection and replacement of anodes ensures continued protection of your marine investment. This zinc anode is recommended for saltwater use only; for freshwater or brackish water applications, consider magnesium or aluminum anodes.
