Technical Specifications

Package Contents

• 1 x Zinc Trim Tab Anode (Replaces 6K1-45371-02)
• Note: Mounting hardware is not included.

Installation Guide

1. Safety First: Before starting, disconnect the engine's battery cables to prevent accidental starting.
2. Locate the Anode: Identify the old trim tab anode on the lower unit (outdrive) of your engine, typically located on the anti-cavitation plate.
3. Remove the Old Anode: Loosen and remove the mounting bolt that secures the old anode. The anode may be difficult to remove if heavily corroded.
4. Clean the Mounting Surface: Thoroughly clean the mounting area on the lower unit. A wire brush can be used to remove any corrosion, paint, or buildup to ensure a clean, metal-to-metal electrical contact.
5. Install the New Anode: Position the new zinc anode and thread the mounting bolt into place.
6. Tighten Securely: Tighten the bolt to the manufacturer's recommended torque specification. Do not over-tighten, but ensure it is secure.
7. Reconnect Battery: Once installation is complete, reconnect the battery cables.

Troubleshooting & FAQ

Q: How can I be sure this anode fits my specific Yamaha engine?
A: This anode is exclusively for left-hand (counter) rotation lower units on Yamaha 150-200 HP models. Double-check the compatibility table on this page with your engine's model and year. Standard rotation engines use a different anode.

Q: What’s the difference between a zinc anode and an aluminum or magnesium one?
A: Zinc anodes, like this one, are specifically formulated for use in saltwater. Aluminum anodes are best for brackish water, and magnesium anodes are for freshwater only. Using the wrong type can lead to inadequate protection or rapid "over-protection" that damages coatings.

Q: How often should I replace my trim tab anode?
A: Anodes should be inspected every few months and replaced when they are 50% corroded or consumed. Replacement frequency depends on water salinity, temperature, and electrical currents in your marina. Never paint an anode, as this will render it ineffective.

Q: What are the signs of a worn or failing trim tab anode?
A: Aside from the anode itself being visibly pitted or dissolved, a key sign of failure is new or accelerated corrosion on other underwater metal components of your lower unit, such as the propeller, gearcase housing, or skeg.
