Installation Notes

  1. Haul the vessel from the water and ensure the sterndrive is safely supported.
  2. Disconnect the boat's battery to prevent electrical hazards.
  3. Locate and unscrew the old, depleted anodes from the Bravo 1 outdrive.
  4. Thoroughly clean the mounting surfaces where the anodes sit, ensuring a bare, clean metal-to-metal connection.
  5. Install the new quick-change adapter plates onto the outdrive using the included hardware.
  6. Attach the new anodes to their respective adapter plates. Ensure all screws are tightened securely.
  7. Perform a final check of all installed components to confirm they are secure.
  8. Reconnect the battery before launching the vessel.

Troubleshooting & FAQ

How does the "Quick-Change" system work?

The kit includes adapter plates that are attached to the sterndrive. The anodes then screw onto these plates. During future changes, you only need to replace the anode itself, not the entire assembly, which significantly reduces installation time.

Is this kit suitable for freshwater, saltwater, or both?

This aluminum anode kit is specifically designed for use in saltwater and brackish water environments. For freshwater-only use, a magnesium kit is recommended.

How often should I inspect and replace these anodes?

Anodes should be inspected during regular maintenance intervals (at least annually) and replaced when they are approximately 50% corroded. The rate of corrosion depends on water salinity, temperature, and electrical currents.

Will this kit fit a MerCruiser Alpha or Bravo 2/3 outdrive?

No, this kit is designed exclusively for MerCruiser Bravo 1 sterndrives (1988-Present). Using it on other models will result in improper fitment and inadequate corrosion protection.

What are the signs that my anodes need replacing?

Visible signs include heavy pitting, a white, crumbly appearance, or a noticeable reduction in size. If the anode is missing or mostly gone, it should be replaced immediately to prevent damage to the outdrive.

Do I need to paint the anodes or the mounting screws?

No. Never paint an anode or the surface it mounts to. Paint acts as an insulator and will prevent the anode from providing the necessary galvanic protection to the metal components of your outdrive.
