Product Details
This Yamaha Trim Tab Anode is a direct-fit replacement designed to protect your engine from galvanic corrosion. It is compatible with a wide range of Yamaha outboards, including 2-stroke models from 60 to 90 HP (1984–2004) and 4-stroke models from T50 to F100 HP (1996–Current). Made from a high-quality zinc alloy, it serves as a sacrificial anode, corroding in place of your engine's vital metal components.
This part is a direct replacement for Yamaha OEM parts 67F-45371-00-00, 688-45371-01-00, and 688-45371-02-00. It also cross-references with Sierra 18-6070, CMP CM6884537102Z, and Tecnoseal 01104.
- Installs easily with a single M10 x 1.25mm bolt.
- Formulated for use in saltwater, freshwater, and brackish environments.
- Provides essential cathodic protection to prevent costly lower unit damage.

Installation Notes
- Tilt the outboard engine to the full "up" position to access the lower unit.
- Locate the existing trim tab anode, typically found on the underside of the anti-cavitation plate.
- Use a socket wrench to remove the mounting bolt securing the old anode. The bolt may be tight due to corrosion.
- Clean the mounting surface on the engine thoroughly, removing any corrosion, salt, or marine growth to ensure a good electrical connection.
- Position the new trim tab anode and align the bolt hole.
- Insert and securely tighten the mounting bolt to the manufacturer's recommended torque specification. Do not overtighten.
- Lower the engine and check that the anode does not interfere with steering or trimming operations.
Troubleshooting & FAQ
How do I know if this anode will fit my engine?
The surest way is to check your OEM part number against the references in the Part Number Matrix. You can also review the Engine & Model Compatibility tables to find your specific engine model and year range.
What are signs that my trim tab anode needs replacing?
Inspect your anode regularly. You should replace it when it appears visually pitted, crumbly, or has eroded to 50% of its original size. A heavily worn anode can no longer provide adequate protection for your engine.
Does this anode include the mounting bolt?
Inclusion of the M10 mounting bolt can vary between aftermarket manufacturers. Please verify with the seller at the time of purchase to confirm if hardware is included.
OEM vs. Aftermarket?
This listing is an aftermarket replacement (not OEM). It has been built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility and batch-inspected for consistency.
