Trim Tab Anode – Fits Yamaha Outboard 40-130 HP (Replaces 6H1-45251-02, 6H1-45251-03)

This trim tab anode is designed for a wide range of Yamaha 2-stroke and 4-stroke outboard engines from 40 HP to 130 HP, covering models from 1990 to 2022. It serves as a crucial component for protecting your engine from galvanic corrosion and assisting with hydrodynamic trim.

This component is a direct replacement for Yamaha OEM part numbers 6H1-45251-02-00 and 6H1-45251-03-00.

• Material: Marine Grade Aluminum Alloy for effective protection in both saltwater and freshwater.
• Installation: Mounts directly to the transom bracket with the included bolts.
• Function: Acts as a sacrificial anode to prevent corrosion and functions as a trim tab to counteract steering torque.

Installation Guide

1. Safety First: Disconnect the battery and ensure the engine is tilted up securely to access the lower unit.
2. Locate Old Anode: Identify the existing trim tab anode, typically located on the underside of the anti-cavitation plate.
3. Remove Old Anode: Use an appropriate wrench to loosen and remove the mounting bolt(s) securing the old anode. The anode may be seized; gentle persuasion may be needed.
4. Clean Mounting Surface: Thoroughly clean the mounting area on the engine bracket. A clean, metal-to-metal connection is essential for the anode to function correctly.
5. Install New Anode: Position the new trim tab anode onto the cleaned surface and align the mounting holes.
6. Secure Bolts: Insert the new mounting bolts and tighten them to the manufacturer-s recommended torque specifications. Do not overtighten.
7. Final Check: Lower the engine and reconnect the battery. The installation is complete.

Troubleshooting & FAQ

Q: How can I be sure this anode fits my specific Yamaha engine?
A: The best way to confirm fitment is to check your engine's model and year against the detailed "Compatible Engine Models" table on this page. You can also cross-reference your existing part number with the numbers listed in our "Part Number Cross-Reference" section.

Q: How often should I replace my trim tab anode?
A: Anodes should be inspected during regular maintenance, at least once a season or every few months in saltwater environments. Replace the anode when it is approximately 50% eroded or consumed to ensure continuous protection.

Q: What does the trim tab anode actually do?
A: It serves two primary functions. First, as a sacrificial anode, its aluminum alloy corrodes instead of the more expensive metal parts of your sterndrive or outboard. Second, its fin shape helps counteract propeller torque for easier, more balanced steering.

Q: Why use an aluminum anode instead of a zinc one?
A: This marine-grade aluminum alloy anode is suitable for use in all water types, including saltwater, brackish water, and freshwater. Zinc anodes are typically effective only in saltwater.
