Yamaha Anodes

Provide the outboard model and year, or serial if available. Then tell us the anode location you are replacing, such as trim tab, plate, or bracket position. Match the anode’s shape, thickness, and hole spacing, and confirm the fixing type. Part numbers from parts diagrams help validate, but photos of the old anode and the mounting point often confirm the details quickly when markings are missing.

Choose based on where you boat most of the time, salt, brackish, or fresh water. Many owners replace like-for-like based on what has worn normally on their outboard. If you are changing material, switch the set together and keep material consistent across the outboard’s protected system. If you tell us your water type and what the anodes fit, it is easier to guide the choice.

Start by confirming correct material for your environment and that all expected anodes are fitted and seated correctly with clean contact. Then consider electrical issues if the boat is kept in a marina, including shore power, chargers, and corroded wiring connections. Also check bonding where applicable. Rapid wear is often an early indicator of a wider issue, so it is worth investigating rather than just replacing more frequently.
