Trim Tab Zinc Anode – Fits Yamaha 115HP 130HP (Replaces 6E5-45371-01-00, 18-6097)

Product Details

This Trim Tab Zinc Anode is engineered for Yamaha 115HP and 130HP outboard motors spanning model years 1996–2016. Designed to protect your engine's lower unit from galvanic corrosion, it provides sacrificial protection in both saltwater and brackish environments, fitting a broad range of standard and counter-rotation models including S, F, VF, and LF series engines.

This anode directly replaces Yamaha OEM part numbers 6E5-45371-01-00, 6L6-45371-00-00, and aftermarket reference 18-6097, ensuring seamless compatibility with your original equipment.

• Zinc alloy construction optimized for saltwater corrosion resistance
• Direct-fit replacement for Yamaha trim tab anode mounting points
• Compatible with 2-stroke and 4-stroke outboard configurations from 1996 to 2016

• 1 × Trim Tab Anode

Installation Notes

1. Disconnect the engine battery or kill switch before beginning work.
2. Tilt the outboard fully up and inspect the trim tab area for existing anode location.
3. Remove the old anode by unscrewing the mounting hardware; clean mounting surfaces of corrosion and debris.
4. Position the new zinc anode onto the trim tab, aligning all mounting holes.
5. Insert and hand-tighten mounting screws, then torque evenly to manufacturer specification.
6. Verify the anode sits flush and does not interfere with trim tab operation.
7. Lower the engine and reconnect the battery; test trim tab function before launching.
8. Inspect the anode every 30–60 days of saltwater use and replace when 50% depleted.

Troubleshooting & FAQ

How often should I replace my trim tab anode?

In saltwater environments, inspect every 30–60 days of use. Replace when the anode has eroded by approximately 50% to ensure continued corrosion protection.

Will this anode fit both 2-stroke and 4-stroke Yamaha engines?

Yes. This trim tab zinc is compatible with both 2-stroke models (6N6, 6N7, 6N8 series) and 4-stroke F-series and VF-series engines from 1996 to 2016, as listed in the compatibility table.

Can I use a zinc anode in freshwater?

Zinc anodes are optimized for saltwater. For freshwater environments, magnesium anodes are typically recommended. In brackish water, zinc is acceptable.

What are the signs that my anode needs replacement?

Look for significant erosion (more than 50% material loss), pitting, or flaking. If the anode appears heavily corroded or thin, replace it immediately to maintain lower-unit protection.

Do I need to apply anti-seize or grease to the mounting surface?

No. The anode must make direct metal-to-metal contact with the trim tab to function correctly. Avoid coatings, paint, or grease on mating surfaces.

Why is my new anode corroding faster than expected?

Rapid anode depletion can indicate stray electrical current, poor bonding, or galvanic exposure from nearby metals. Inspect all electrical connections and grounding straps.
