Installation Notes
- Disconnect the engine's battery before starting work.
- Locate and unbolt the old, corroded anodes from the gearcase and trim tab areas. Note their positions.
- Thoroughly clean the mounting surfaces on the engine. A wire brush or sandpaper works well to remove any buildup or oxidation.
- Ensure the surface is bare metal for proper electrical conductivity. Do not apply paint or grease between the anode and the engine.
- Fasten the new anodes securely in place of the old ones. Use the correct torque settings if specified by your engine manual.
- Once all anodes are installed, you may reconnect the battery.
Troubleshooting & FAQ
How do I know if this kit will fit my engine?
This anode kit is specifically designed for Yamaha 80 HP and 100 HP 4-stroke outboard models. Please check the compatibility table on this page to confirm your model is listed and cross-reference the OEM part number KITY80-100AL.
Why should I use aluminum anodes over zinc?
Aluminum anodes are the preferred choice for saltwater and brackish water environments. They provide superior, longer-lasting protection compared to traditional zinc anodes in these conditions and activate more reliably in brackish water.
How often do I need to replace my anodes?
Anodes should be inspected at least once a year, or every 50-100 hours of use. You must replace them when they appear to be 50% corroded or consumed to ensure your engine remains protected.
What are the signs of a failing or depleted anode?
Visible signs include a white, chalky buildup on the anode or, more critically, new signs of corrosion, pitting, or paint blistering on the engine's gearcase, bracket, or other submerged metal parts. This indicates the anodes are no longer sacrificing themselves and need immediate replacement.
