Aluminum Alloy Anode – Fits Yamaha Outboard 40-130 HP (Replaces 6H1-45251-02-00, 6H1-45251-03-00)

This aluminum alloy bar anode is designed to fit a wide range of Yamaha 40 HP to 130 HP 2-stroke and 4-stroke outboard engines, covering models from approximately 1999 to 2016.

It serves as a direct aftermarket replacement for Yamaha part numbers 6H1-45251-02-00 and 6H1-45251-03-00, offering reliable corrosion protection for your engine's transom bracket.

• Material: Marine-grade aluminum alloy provides superior, longer-lasting protection than zinc in both fresh and salt water environments.
• Installation Method: Simple bolt-on installation onto the transom bracket.
• Protection: Essential for preventing galvanic corrosion on underwater metallic components of your outboard.

Package Contents

• 1 x Aluminum Alloy Anode (Replaces 6H1-45251-02-00)

Installation Guide

1. Locate and remove the old transom bracket anode from the outboard motor. This may require specific tools to loosen corroded bolts.
2. Clean the mounting surface on the bracket thoroughly to ensure a good electrical connection with the new anode.
3. Position the new aluminum anode onto the bracket, ensuring the mounting holes are properly aligned.
4. Insert the mounting bolts and washers (not included) through the anode and bracket.
5. Tighten the bolts securely. Do not overtighten, as this can damage the anode or the engine bracket.
6. Confirm the anode is firmly seated and makes solid contact with the metal of the bracket.

Troubleshooting & FAQ

Q: How do I confirm this anode fits my Yamaha engine?
A: This anode is designed for most Yamaha 40-130 HP 2-stroke and 4-stroke outboards from 1999–2016. The best way to confirm is to check the "Compatible Engine Models" table on this page. You should also cross-reference your existing part number with our "Part Number Cross-Reference" table to ensure it matches one of the listed numbers, such as 6H1-45251-02-00 or 6H1-45251-03-00.

Q: What is the difference between this aluminum anode and a zinc anode?
A: This anode is made from a military-spec aluminum alloy. Aluminum anodes provide longer-lasting protection than traditional zinc anodes and are effective in all water types (fresh, brackish, and salt). Zinc anodes are generally recommended for saltwater use only and can become inactive in freshwater.

Q: How often should I replace my transom anode?
A: Anodes should be inspected regularly (at least annually) and replaced when they are 50-75% corroded. The rate of corrosion depends on water salinity, temperature, and electrical activity. A depleted anode can no longer protect your engine from galvanic corrosion.

Q: Does this anode include mounting bolts and washers?
A: This listing is for the anode only. Mounting hardware (bolts and washers) is not included and must be purchased separately to ensure you have the correct size and material for your specific engine model.

Q: OEM vs. Aftermarket?
A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.

Q: How fast do you ship and how much does it cost?
A: We offer fast global shipping—typically 5–15 days worldwide—and standard shipping is free. Expedited options are available at checkout depending on your location.

Q: What is your warranty and return policy?
A: This product includes a 1-year warranty against manufacturing defects under normal use. If something goes wrong, contact our support team with your order details. Returns are accepted within our standard return window (unused & in original condition); please see our policy page or reach out for instructions.
