What’s in the Box

  • Anodes for flag/gearcase

Installation Notes

  1. Disconnect the battery before starting work.
  2. Locate and remove the old anodes from the gearcase and trim tab area. Clean the mounting surfaces thoroughly to ensure a good electrical connection.
  3. Install the new anodes onto the clean surfaces. Ensure they are securely fastened but do not overtighten the bolts.
  4. Do not paint the new anodes, as this will prevent them from functioning correctly.
  5. Reconnect the battery and test engine functions.

Troubleshooting & FAQ

How can I be sure this kit fits my specific Yamaha model?

This kit is designed for a broad range of Yamaha 200–300 HP outboards. The best way to confirm fitment is to check your engine's model and year against the detailed compatibility table on this page. Also, visually compare the anode shapes in the product images to your existing anodes.

Why choose an aluminum anode over zinc or magnesium?

Aluminum anodes are the best all-around choice for saltwater and brackish water. They offer a longer service life than zinc and are more effective in varied salinity levels. They are not typically recommended for freshwater use, where magnesium is preferred.

How do I know when my anodes need to be replaced?

Anodes should be inspected during regular maintenance and replaced when they are 50% corroded. Signs of advanced wear include heavy pitting, crumbling, or a significant reduction in mass. A proactive replacement schedule prevents damage to your engine.

Is mounting hardware included with the kit?

This kit contains the anodes only. In most cases, the original mounting hardware can be cleaned and reused if it is in good condition and free of corrosion. If the hardware is stripped or corroded, it should be replaced.

OEM vs. Aftermarket?

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
