Product Details
This aluminum trim tab anode is an aftermarket sacrificial anode for selected Yamaha outboard lower units with left-hand, counter-rotation configurations. Catalog information identifies the application as Yamaha 120 HP and 200 HP counter-rotation outboards using Yamaha OEM part number 6K1-45371-02.
The aluminum construction is intended for marine corrosion protection, including saltwater service. As the sacrificial anode corrodes in service, it helps protect compatible underwater metal components from galvanic corrosion.
- Aluminum trim tab anode for selected Yamaha counter-rotation outboards.
- Application identified for 120 HP and 200 HP counter-rotation configurations.
- Replacement reference for Yamaha OEM part number 6K1-45371-02.
- Designed as a direct replacement-style component; verify the original anode shape and mounting arrangement before ordering.
Part Number Reference
Use the following manufacturer reference to compare the replacement with your original part.
| Brand | Part Number | Reference Type |
|---|---|---|
| Yamaha | 6K1-45371-02 | OEM reference |
Engine Compatibility
Compatibility must be confirmed by the exact engine configuration and lower-unit rotation. The catalog application associated with this reference is limited to selected Yamaha 120 HP and 200 HP counter-rotation outboards.
| Brand | Rated Horsepower | Rotation | Stroke or Year | OEM Reference | Fitment Notes |
|---|---|---|---|---|---|
| Yamaha | 120 HP | Left-hand / counter rotation | Not specified | 6K1-45371-02 | Selected compatible configurations only |
| Yamaha | 200 HP | Left-hand / counter rotation | Not specified | 6K1-45371-02 | Selected compatible configurations only |
Important: This listing should not be used to confirm fitment for every Yamaha 150–200 HP engine, every model year, or standard-rotation lower units. Yamaha model designations, rotation, shaft configuration, and lower-unit design must match the original application.

- 1 x Aluminum trim tab anode
Mounting hardware is not confirmed as included. Reuse hardware only if it is in serviceable condition and matches the engine manufacturer's requirements.
Installation Notes
- Make sure the engine is turned off, secured, and safely supported before beginning work.
- Remove the original trim tab anode and retain the original hardware for comparison.
- Clean corrosion, paint, and debris from the mounting interface so the replacement anode can make proper electrical contact with the lower unit.
- Compare the replacement's shape, mounting hole, and orientation with the original part before installation.
- Install the anode in the original position and tighten the fastener according to the engine service information. Do not overtighten.
- After installation, confirm that the anode is secure and clear of moving components.
Maintenance and FAQ
How do I confirm that this anode fits my engine?
Confirm that your Yamaha outboard uses OEM reference 6K1-45371-02 and has a left-hand, counter-rotation lower unit. Also compare the original anode's shape and mounting arrangement. Horsepower alone is not sufficient to confirm fitment.
Is this an aluminum or zinc anode?
This replacement is an aluminum anode. The original product description incorrectly identified it as zinc, so the material statement has been corrected.
Can I use this on a standard-rotation Yamaha outboard?
Do not use this part on a standard-rotation engine unless the exact engine parts information confirms the same OEM reference and application. The documented application is for counter-rotation configurations.
Does this fit all Yamaha 150–200 HP models?
No. The available catalog application identifies 120 HP and 200 HP counter-rotation configurations, not every Yamaha 150–200 HP model. Verify the exact model and lower-unit configuration before ordering.
When should the anode be replaced?
Inspect the anode regularly, especially after extended saltwater use. Replace it when it is substantially consumed, deeply pitted, loose, or no longer maintains its original protective shape. Follow the engine manufacturer's maintenance guidance where available.
Is this an OEM Yamaha part?
No. This listing is for an aftermarket replacement component that references Yamaha OEM part number 6K1-45371-02 for application identification.
Safety and Fitment Information
- Verify the OEM reference, rotation direction, anode shape, and mounting arrangement before purchase.
- Do not rely on horsepower alone to determine compatibility.
- Do not paint, coat, or electrically isolate the anode from the lower unit.
- Use appropriate lifting, support, and personal-protection practices during installation.
- Professional installation is recommended when the correct application or installation procedure is uncertain.
