Trim Tab Anode for Yamaha V4 115–130 HP and V6 Outboards – Replaces 6E5-45371-01, 18-6097

Product Details

This Trim Tab Anode is a direct-fit replacement for the trim-tab anode used on selected Yamaha V4 outboards rated at 115–130 HP and selected Yamaha V6 outboards. The anode provides sacrificial corrosion protection for the outboard's lower-unit and trim-tab area by corroding in preference to protected metal components.

The company fitment record identifies this part for Yamaha V4 115–130 HP and V6 applications. Exact compatibility can vary by model, year, lower-unit configuration, and serial range, so compare the original anode and the engine's parts diagram before ordering.

• Replacement trim-tab anode for selected Yamaha outboards
• Fits the original trim-tab mounting location when the application matches
• Cross-referenced to Yamaha OEM part number 6E5-45371-01
• Aftermarket reference 18-6097
• Sold as one individual anode

Part Number References

These references are provided to help compare the original part with this replacement. They do not replace confirmation of the complete engine model and application.

Engine and Model Compatibility

The primary company fitment is Yamaha V4 115–130 HP and V6 outboards. Catalog references for the OEM number include selected Yamaha 115A/B/C, F115A/B, and 130B applications, as well as additional V6 applications. Because catalog records may cover different configurations, use the engine model and serial information to confirm the match before installation.

What's in the Box

• 1 × Trim Tab Anode

Mounting hardware is not listed as included. Reuse only hardware that is serviceable and appropriate for the original application.

Installation Notes

1. Switch off the engine and remove the ignition key. Follow the engine manufacturer's safety procedures before working near the lower unit.
2. Raise and securely support the outboard, then locate the trim-tab anode.
3. Remove the existing anode and inspect the mounting hardware and contact surfaces.
4. Clean corrosion and debris from the mating surfaces without applying paint, grease, or other insulating coatings between the anode and its mounting surface.
5. Position the replacement anode in the original orientation and install the serviceable mounting hardware.
6. Tighten the hardware to the engine manufacturer's specification. Do not rely on a generic torque value.
7. Confirm that the anode is secure and does not interfere with steering, trim, or other lower-unit movement.
8. Inspect the anode regularly and replace it when substantially eroded or when the manufacturer's service guidance calls for replacement.

Troubleshooting and FAQ

How do I confirm that this anode fits my Yamaha outboard?

Compare the original anode's shape, mounting pattern, and OEM reference with this listing. Then confirm the complete engine model, year, and serial range in the appropriate Yamaha parts diagram. The broad application is Yamaha V4 115–130 HP and V6 outboards, but not every engine in those families is necessarily confirmed.

What does a trim-tab anode do?

A trim-tab anode is a sacrificial corrosion-protection component. It is designed to wear instead of more valuable metal components when the anode and engine bonding system are functioning correctly.

When should the anode be replaced?

Inspect it regularly, especially after use in saltwater or brackish water. Replace it when it is heavily eroded, deeply pitted, loose, or no longer provides sufficient material for sacrificial protection.

Can I paint or grease the anode?

Do not paint the anode or coat the electrical contact surface with grease or sealant. The anode must maintain proper metal-to-metal contact with its mounting surface to work as intended.

Can I use this anode in freshwater?

Anode material selection depends on the water type and the engine manufacturer's recommendations. Confirm the recommended anode material for your operating environment before installation; this listing does not specify a material composition.

Why is the anode wearing unusually quickly?

Rapid wear may be associated with water conditions, stray electrical current, poor bonding, incompatible nearby metals, or an incorrect anode application. Inspect the bonding system and have the installation checked if wear is abnormal.

Is this an OEM part?

No. This listing is for an aftermarket replacement referenced to Yamaha OEM part number 6E5-45371-01 and aftermarket reference 18-6097. Yamaha and Sierra are registered trademarks of their respective owners.

Safety and Important Information

• Verify the complete engine model, year, serial range, and original part before ordering.
• Do not assume compatibility from horsepower alone; V4, V6, shaft length, counter-rotation, and lower-unit configuration can affect fitment.
• Use the manufacturer's installation and torque specifications for your engine.
• This is an aftermarket replacement, not an OEM-manufactured component.
• Professional installation is recommended when the correct application or mounting procedure is uncertain.
