Installation Notes
- Disconnect the engine's battery before beginning work.
- Locate and unbolt the existing anodes from the gimbal housing and ventilation plate.
- Thoroughly clean the mounting surfaces where the new anodes will sit. A wire brush can be used to remove any corrosion or residue.
- Position the new anodes and fasten them securely. Ensure there is firm, direct metal-to-metal contact.
- Do not apply any paint, grease, or coatings to the anodes or the mounting surface, as this will prevent them from working correctly.
- Once installation is complete, reconnect the battery.
Troubleshooting & FAQ
How do I know if this kit fits my Yamaha engine?
This kit is designed for Yamaha 200-300 HP outboards. To ensure a perfect match, check the 'Engine & Model Compatibility' table and verify your specific engine model and original part numbers (6G5-45251-01A, 61A-45371-00A) before ordering.
What is the difference between aluminum and zinc anodes?
Aluminum anodes are specifically designed for superior performance in both salt and brackish water, offering longer-lasting and more effective protection than traditional zinc anodes in these environments. Zinc anodes are generally suitable only for saltwater applications.
How often should I replace these anodes?
It is recommended to inspect your anodes at least every six months. You should replace them when they are approximately 50% consumed or show signs of severe pitting. Regular replacement is crucial for protecting your engine from galvanic corrosion.
What are the signs that an anode needs replacing?
Visible signs include significant reduction in size (50% or more), deep pitting, or the anode material crumbling away. A heavily corroded anode is no longer effective and should be replaced immediately to protect underwater metallic components.
Do I need special tools for installation?
No special tools are required. Installation can typically be completed using a standard set of wrenches or sockets to remove the old anodes and secure the new ones.
Is it okay to paint my new anodes?
No. Never paint an anode. Paint will create a barrier that insulates the anode, rendering it useless and leaving your engine vulnerable to corrosion. Anodes must have direct, uninhibited contact with both the water and the metal they are protecting.
