Installation Notes
- Disconnect the engine's battery cables before beginning work.
- Locate and unbolt the old, corroded anodes from the lower unit, transom bracket, and engine block.
- Thoroughly clean the mounting surfaces where the new anodes will sit. Ensure all corrosion, paint, and debris are removed to guarantee good metal-to-metal contact.
- Securely fasten the new anodes using the provided hardware. Do not apply paint over the anodes, as this will prevent them from working correctly.
- Once all anodes are installed and tightened, reconnect the battery cables.
- Check anodes periodically as part of your regular maintenance schedule.
Troubleshooting & FAQ
How often should I inspect and replace my anodes?
Anodes should be inspected at least every six months and replaced when they are 50% consumed. The rate of corrosion can vary significantly based on water salinity, temperature, and electrical currents.
Can I use this aluminum kit in freshwater?
No. This aluminum anode kit is specifically formulated for saltwater and brackish water. Using it in freshwater can lead to the buildup of an oxide layer that passivates the anode, rendering it ineffective. For freshwater use, a magnesium anode kit is required.
What are the signs that my anodes are failing or need replacement?
Visible signs include heavy pitting, crumbling, or a noticeable reduction in size. If the anode appears more than half-eroded compared to its new state, it's time for replacement.
What is the difference between this kit and the CMY4060KIT?
This kit (CMY4050KITA) is primarily for 2-stroke models, while the CMY4060KIT is specifically configured for 4-stroke 40-60HP Yamaha outboards and contains a different set of anodes and quantities.
