Troubleshooting & FAQ

How do I know if this anode kit fits my engine?

This kit is designed for Yamaha 40, 50, and 60 HP outboard engines (both 2-Stroke and 4-Stroke). To ensure a perfect match, please review the compatibility table and cross-reference your existing part number with KITY40-60AL.

Why use an aluminum anode instead of zinc?

Aluminum anodes offer superior performance in a wider range of water conditions, including saltwater, brackish, and freshwater. They have a higher electrical potential than zinc, providing more active and longer-lasting protection against galvanic corrosion for your engine.

When should I replace my anodes?

Anodes should be inspected during routine maintenance and replaced when they are approximately 50-75% consumed. The rate of corrosion depends on factors like water salinity, temperature, and nearby electrical currents. We recommend checking them at least once a season or every 100 hours of use.

What are the signs of a failing anode?

A failing anode will appear heavily pitted, crumbled, or significantly reduced in size. If you notice new or accelerated corrosion on your propeller, gearcase, or other underwater metal parts, it is a clear sign your anodes are depleted and must be replaced immediately.
