Installation Notes
- Disconnect the battery to prevent accidental starts.
- Remove the old, corroded anodes from the sterndrive. Note their positions if you are unfamiliar with the layout.
- Thoroughly clean the mounting surfaces on the sterndrive. A wire brush is effective for removing corrosion and bio-fouling to ensure good electrical contact.
- Position the new anodes. Do not paint anodes or the mounting surfaces, as this will insulate them and prevent them from working.
- Securely fasten the new anodes using the included hardware. Ensure bolts are tightened to the manufacturer's specified torque.
- After the first use in water, visually inspect the anodes to confirm they are secure and making proper contact.
Troubleshooting & FAQ
Do these anodes fit all MerCruiser Bravo One drives?
This kit is designed for MerCruiser Bravo One, including standard and XR models, manufactured from 1988 onwards with serial number 0B664190 and up. Always verify your serial number to ensure correct fitment.
Why use an aluminum anode instead of zinc or magnesium?
Aluminum anodes are versatile and effective in all water types: saltwater, brackish, and freshwater. Zinc is only effective in saltwater, while magnesium is best for freshwater-only use and can corrode too quickly in saltwater.
How often should I inspect or replace my sterndrive anodes?
A visual inspection is recommended at least annually or every 100 hours of operation. Replace anodes when they are approximately 50% corroded to ensure the sterndrive remains protected.
What are the signs that my anodes need replacing?
Visible signs include significant pitting, crumbling, or the anode being worn down to about half of its original size. If the anode appears white and chalky, that indicates it is working correctly, but it still needs replacement once sufficiently worn.
Is all necessary hardware included for installation?
Yes, this is a complete kit that includes all five anodes and the corresponding attaching hardware required for a full replacement.
