Mounting hardware is not identified in the company package information. Reuse hardware only if it is serviceable and correct for the engine application, or obtain the required hardware separately according to the engine service information.
Installation Notes
- Turn off the engine, remove the ignition key, and secure the boat before beginning work.
- Locate the existing trim tab anode on the lower unit.
- Remove the existing anode and retain the original hardware if it is suitable for reuse.
- Clean corrosion, paint, marine growth, and residue from the mounting surfaces. Good metal-to-metal contact is necessary for an anode to work correctly.
- Position the replacement anode in the same orientation as the original part and align the mounting hole.
- Install the correct hardware and tighten it according to the applicable Yamaha service specifications. Do not over-tighten.
- Inspect the anode regularly and replace it before it is substantially depleted or no longer makes reliable electrical contact.
Troubleshooting & FAQ
What engines is this anode intended for?
The company catalog specifies Yamaha 80–100 HP four-stroke outboards. Confirm the exact model, year, shaft configuration, serial range, original anode shape, and manufacturer reference before ordering.
Will this fit a Yamaha 60, 70, or 90 HP model?
Those applications are not the stated company fitment for this product. Do not rely on horsepower alone; use the exact engine identification and compare the original anode reference before purchasing.
Is this an anode kit?
No. The company record identifies this as a single anode, not a multi-piece anode kit.
Does the package include a mounting bolt?
Mounting hardware is not identified in the company package information. Check the original hardware and the applicable engine service information before installation.
Why does an anode wear away?
An anode is designed to erode over time while helping protect connected metal components from galvanic corrosion. Rapid or uneven wear may indicate severe galvanic activity, stray electrical current, poor bonding, or unsuitable anode selection.
Can I paint or coat the anode?
No. Paint, heavy corrosion, sealant, or other coatings on the contact surfaces can interrupt the electrical connection required for sacrificial protection.
How should I confirm compatibility?
Compare the complete manufacturer reference, anode shape, mounting location, engine model, horsepower, stroke, year, shaft configuration, and serial-number information. If any of these details differ, confirm fitment using the engine service information before ordering.
Is this an OEM Yamaha component?
This listing is for a replacement anode. It is not represented as a genuine Yamaha-branded component.
Safety & Important Info
- Verify the exact engine model, year, stroke, shaft configuration, serial range, and original part number before purchase.
- Do not use the broad horsepower range as the only compatibility check.
- Do not paint, coat, or insulate the anode or its contact surface.
- Use the correct hardware and tightening procedure for the specific engine application.
- Professional installation is recommended when the lower unit or mounting hardware is damaged or heavily corroded.
