Product Details
This aluminum trim tab anode is an aftermarket replacement for the Yamaha outboard anode identified by OEM part number 6H1-45251-02. The cataloged application covers Yamaha outboards in the 40–90 HP range. It is designed to provide sacrificial corrosion protection for the outboard's submerged metal components.
The corresponding aftermarket catalog reference is GLM 12884. Confirm the OEM number stamped or listed for your original part before ordering. The 40–90 HP range is a general application guide and does not replace verification of the exact engine model, year, and mounting configuration.
- Aluminum sacrificial anode for Yamaha outboard applications.
- Application range listed by the catalog: 40–90 HP.
- Replaces Yamaha OEM reference 6H1-45251-02.
- Helps reduce galvanic corrosion when correctly installed and maintained.

Engine Compatibility
The available catalog application identifies this anode for Yamaha outboards from 40 HP through 90 HP. The available source does not establish one universal model, year, stroke, shaft-length, or serial-number range for every engine in that horsepower range. Check the original anode, OEM number, mounting shape, and your engine's exact service information before purchase.

Installation and Maintenance
- Turn off the engine and follow the manufacturer's safety procedures before servicing the outboard.
- Compare the replacement anode with the original part and verify the OEM reference and mounting pattern.
- Remove the worn anode and clean corrosion, paint, sealant, and debris from the contact surfaces.
- Install the new anode in the original orientation using the correct fasteners and the engine manufacturer's torque requirements.
- Do not paint, coat, or electrically isolate the anode from its mounting surface.
- Inspect the anode regularly and replace it when substantially consumed, damaged, or no longer making reliable electrical contact.
Troubleshooting & FAQ
What OEM number does this anode replace?
This replacement is cataloged for Yamaha OEM part number 6H1-45251-02. Verify the number and physical fit against your original part before ordering.
What Yamaha horsepower range is listed for this part?
The available catalog reference lists this anode for Yamaha outboards from 40 HP to 90 HP. Horsepower alone is not sufficient to confirm fitment; model, year, mounting configuration, and OEM number should also match.
Does this part fit Yamaha 100–130 HP outboards?
Do not rely on this listing for 100–130 HP applications. The available catalog reference identifies the 6H1-45251-02 anode for 40–90 HP, so a different anode should be verified for higher-horsepower engines.
Why does an outboard need a trim tab anode?
The anode is designed to corrode preferentially and help protect compatible metal components from galvanic corrosion. It must remain electrically connected to the engine and should be replaced as it is consumed.
Is this an OEM Yamaha part?
No. This is an aftermarket replacement for the Yamaha OEM reference listed above. Yamaha is referenced only for application and part-number identification.
How can I confirm fitment?
Compare your original anode's part number, shape, mounting location, and contact surface. Confirm that your engine falls within the cataloged 40–90 HP range and consult the engine manufacturer's parts information when the model, year, or serial range is uncertain.
Safety & Important Information
- Always verify the exact OEM number and physical configuration before installation.
- Do not use the horsepower range alone as proof of compatibility.
- Incorrect anode selection or poor electrical contact can reduce corrosion protection.
- This is an aftermarket replacement, not an OEM Yamaha component.
- Professional installation is recommended when the correct application or installation torque is uncertain.
