Installation Notes
- Before starting, disconnect the engine's battery cables to prevent accidental starting.
- Locate the existing transom bracket anode on your outboard motor. It is typically a small, rectangular metal bar bolted to the bracket.
- Unscrew the mounting bolts holding the old anode in place and remove it. You may need to clean the area if there is significant corrosion or buildup.
- Thoroughly clean the mounting surface on the engine bracket to ensure a solid electrical connection. A bare metal-to-metal contact is essential for the anode to work correctly.
- Position the new anode onto the bracket, aligning the bolt holes.
- Install and securely tighten the new mounting bolts. Do not over-torque.
- Once the new anode is firmly in place, you can reconnect the battery cables.
Troubleshooting & FAQ
Will this anode fit my specific Yamaha model?
This anode is designed for a wide range of Yamaha 40-130 HP outboards from 1999–2016. Please review the detailed "Engine & Model Compatibility" table and cross-reference your engine's model and year to ensure a perfect match.
Is aluminum better than zinc for my engine?
Aluminum alloy anodes offer broader protection than zinc. They are effective in fresh, brackish, and salt water, whereas zinc is primarily for saltwater use and can become inactive in fresh water. Aluminum also provides longer-lasting protection, reducing the frequency of replacement.
How do I know when it's time to replace my anode?
You should inspect your anodes at least once a year or every 100 hours of use. We recommend replacement when the anode is approximately 50% corroded or visibly eroded, pitted, or crumbling. Losing half its mass significantly reduces its ability to protect your engine.
What are the signs of a failing anode?
A failing or depleted anode will not show much change, but you will notice accelerated corrosion on other metal parts of your engine, such as the propeller, gearcase, or transom bracket. If you see new or worsening pitting and galvanic corrosion on these components, your anode is likely not working.
Does this anode come with mounting bolts?
The package contains the anode itself. While the anode is designed to be installed with bolts and washers, the input data does not confirm their inclusion in this specific package. You may need to reuse your existing hardware if it is in good condition, or source appropriately sized bolts separately.
What is the difference between this and a genuine Yamaha part?
This is a high-quality aftermarket part designed to meet or exceed OEM specifications for fit, material, and performance. While it is not branded as a Yamaha OEM part, it offers a comparable level of protection and is manufactured in a certified facility to ensure quality and reliability at a better value.
OEM vs. Aftermarket?
This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
Shipping speed & cost?
