• 1 x Trim Tab Anode (6E5-45371-01-00)

Installation Guide

Always consult your owner's manual or a certified marine technician for model-specific instructions. The general steps are as follows:

1. Safety First: Tilt the engine up and disconnect the battery to prevent accidental starting.
2. Locate Anode: Identify the old trim tab anode, typically located on the underside of the anti-cavitation plate.
3. Remove Old Anode: Use a socket wrench to remove the bolt securing the anode. It may be tight due to corrosion.
4. Clean Surface: Thoroughly clean the mounting surface on the lower unit. A wire brush or sandpaper works well to ensure a clean metal-to-metal connection for proper electrical conductivity.
5. Install New Anode: Position the new anode and insert the mounting bolt.
6. Tighten Bolt: Securely tighten the bolt to the manufacturer's recommended torque specification. Do not overtighten.
7. Final Check: Lower the engine and reconnect the battery.

Troubleshooting & FAQ

How do I confirm this fits my engine?
This anode fits a wide range of Yamaha 115-225 HP outboards. Please check the "Compatible Engine Models" table and cross-reference your engine's model and year. Verifying that the OEM part number 6E5-45371-01-00 matches your service manual's recommendation is the most reliable method.

How often should I replace my trim tab anode?
Anodes should be inspected during regular maintenance (at least annually) and replaced when they are 50-75% corroded. The rate of corrosion depends heavily on water conditions (saltwater causes faster erosion than freshwater) and usage.

What are the signs that a trim tab anode needs replacing?
Visible signs include heavy pitting, crumbling, or a significant reduction in the anode's original size. A white, powdery coating indicates the anode is functioning correctly but may be nearing the end of its service life. If you notice unusual corrosion on other metal parts of your lower unit, the anode is likely depleted and requires immediate replacement.
