Trim Tab Anode – Fits Yamaha 150-200 HP Outboards (Replaces 6K1-45371-01-00, 6K1-45371-02-00)

This trim tab anode is designed for a wide range of Yamaha 150-200 HP outboard engines, including 2-Stroke L150/L200 models (1987–1999) and 4-Stroke models like the LZ150 (2000–2006), LF150 (2005–2024), LZ200 (2000–2012), and LF200 (2012–2024). It provides essential protection against galvanic corrosion in marine environments and assists in hydrodynamic trim adjustment.

This component is a direct replacement for Yamaha parts 6K1-45371-01-00 (standard rotation) and 6K1-45371-02-00 (counter-rotation), as well as several aftermarket equivalents. It ensures proper fit and function, helping to safeguard your engine's lower unit from costly damage.

• Material: Constructed from high-quality, marine-grade zinc alloy for superior sacrificial protection in saltwater, freshwater, and brackish conditions.
• Dual Function: Acts as both a sacrificial anode to prevent corrosion and a trim tab to help correct steering torque.
• Installation: Features a direct bolt-on design for straightforward installation with the included fastener.

Technical Specifications

Package Contents

• 1 x Zinc Trim Tab Anode (Replaces 6K1-45371-01-00 or 6K1-45371-02-00)
• 1 x Mounting Bolt

Installation Guide

1. Safety First: Turn off the engine and remove the key. Tilt the outboard to the full "up" position to access the lower unit.
2. Locate the Anode: Identify the old trim tab anode, which is typically located on the underside of the anti-cavitation plate, just above the propeller.
3. Remove the Old Anode: Use a socket wrench to loosen and remove the single mounting bolt securing the anode. The anode may be tight due to corrosion.
4. Clean the Mounting Surface: Thoroughly clean the mounting area on the lower unit. Remove any corrosion, salt, or marine growth to ensure a solid electrical connection, which is critical for the anode to function correctly.
5. Install the New Anode: Position the new trim tab anode onto the cleaned surface, aligning the bolt hole.
6. Secure the Bolt: Insert the new mounting bolt and tighten it securely. Do not overtighten. The anode should be firmly in place without any movement.

Troubleshooting & FAQ

Q: How do I know whether to use the standard or counter-rotation version?
A: This part replaces both Yamaha 6K1-45371-01-00 (standard rotation) and 6K1-45371-02-00 (counter-rotation). While physically similar, the fin is angled differently to counteract propeller torque. Consult your service manual or a certified technician to confirm which part number your specific engine model requires.

Q: How often should I replace my trim tab anode?
A: Anodes should be inspected during regular maintenance intervals (at least annually) and replaced when they are 50% corroded. The rate of corrosion depends on your boat's electrical system, water salinity, and usage.

Q: What are the signs that my anode needs replacement?
A: Visible signs include heavy pitting, crumbling, or a significant reduction in size. A worn-out anode will no longer protect your engine's metallic components from galvanic corrosion. You may also notice a change in steering effort if the trim tab function is compromised.
