Yamaha Anode Kit 90798-1M772-00 – OEM Corrosion Protection for Mid-Range Outboards
This genuine Yamaha anode kit delivers essential corrosion protection for your mid-range outboard engine. Engineered to Yamaha's exacting standards, the 90798-1M772-00 kit includes both trim-tab and lower anodes designed to safeguard critical engine components in saltwater and brackish environments.
Key Specifications
The kit comprises two precision-cast anodes: 67C-45371-00 and 67C-45251-00. Both components are manufactured from high-grade sacrificial alloy that corrodes preferentially, protecting your engine's aluminium and steel surfaces from galvanic damage. Supplied as a matched set, these anodes ensure balanced protection across the lower unit and trim system.
Compatible Yamaha Outboard Models
This kit is factory-specified for Yamaha F30B, F40F, F40H, F50H, and F60F outboard engines. It supersedes earlier kit number KIT-60000-AN-A0, offering improved material formulation and extended service life. Always verify your engine model and serial number before ordering to ensure correct fitment.
Corrosion Protection & Maintenance
Regular anode replacement is critical to preventing costly corrosion damage. Inspect anodes every 100 operating hours or at the start of each season, and replace when 50% depleted. This kit simplifies maintenance by bundling both trim-tab and lower anodes in a single package, ensuring you have the correct parts on hand when service is due.
Applications & Uses
Ideal for commercial operators, charter fleets, and recreational boaters running Yamaha mid-range outboards in marine environments. Whether you're maintaining a single engine or managing a fleet, this OEM kit delivers the reliability and corrosion resistance Yamaha engines are known for.
