Installation Notes
- Disconnect the engine's battery before beginning installation.
- Locate and unbolt the old, depleted anodes from the transom and skeg (lower unit).
- Thoroughly clean the mounting surfaces where the anodes will sit. Ensure all paint, marine growth, and corrosion are removed for direct metal-to-metal contact.
- Position the new anodes and fasten them securely with the provided hardware. Do not overtighten the bolts.
- Do not paint or apply any coating to the new anodes, as this will prevent them from functioning.
- Once installation is complete, reconnect the battery. Inspect the anodes periodically as part of your regular maintenance schedule.
Troubleshooting & FAQ
How do I know this kit fits my Yamaha outboard?
This kit is specifically designed for Yamaha 60-90 horsepower 2-stroke outboard models. Always verify by comparing the part numbers in the Part Number Matrix to your service manual's requirements.
What's the difference between aluminum and zinc anodes?
Aluminum anodes are recommended for use in both saltwater and brackish water, offering broader protection. Zinc anodes are typically used for saltwater-only applications. This aluminum kit provides versatile performance.
How often should I replace my engine's anodes?
Anodes should be inspected at least once a year, or every 6 months in aggressive saltwater environments. They should be replaced when they are 50-75% corroded or appear visibly pitted and crumbled.
What are the signs that my anodes need replacing?
Visible signs include significant pitting, crumbling, or a noticeable reduction in size compared to a new anode. If the anode looks "eaten away," it's time for a replacement.
Why is it important to clean the mounting surface before installing?
A clean, bare metal mounting surface is critical for good electrical conductivity. If the anode isn't in direct electrical contact with the metal it's protecting, it cannot provide effective galvanic corrosion protection.
Can I use this aluminum anode kit in freshwater?
While aluminum anodes will work in freshwater, they are optimized for salt and brackish water. For boats used exclusively in freshwater, magnesium anodes are the most effective choice.
Is this an OEM part?
This listing is for an aftermarket replacement part, not an OEM component. It is engineered to meet or exceed OEM-level specifications using comparable high-quality materials and is manufactured in an ISO 9002 certified facility with batch inspections to ensure consistency and performance.
