Installation Notes

Safely secure the vessel and disconnect the battery. Tilt the outboard motor to the full "up" position.
Locate the existing trim tab anode on the underside of the anti-cavitation plate.
Use a socket wrench to remove the mounting bolt and detach the old anode. Note its orientation or any adjustment markings.
Thoroughly clean the mounting surface on the lower unit, removing any corrosion, salt, or marine growth to ensure proper electrical contact.
Position the new anode and insert the mounting bolt. Hand-tighten initially.
Tighten the bolt to the manufacturer's specified torque. Do not overtighten.
Lower the motor, reconnect the battery, and check for proper operation.

Troubleshooting & FAQ

How do I know if this trim tab anode fits my engine?

This anode is designed for a wide range of Yamaha outboards, primarily 115-200 HP models from 1984 to current. Please consult the "Engine & Model Compatibility" table and cross-reference your engine's model and year. Verifying the OEM part number (6E5-45371-01-00) is the most reliable method.

What are the signs that my old anode needs replacement?

Anodes should be replaced when they are 50-75% corroded or "eaten away." Visual signs include pitting, crumbling, or significant reduction in size. Poor steering performance or a noticeable pull to one side while on plane can also indicate a worn or improperly adjusted trim tab.

How often should I replace this anode?

Replacement frequency depends on your boat's usage, water conditions (saltwater vs. freshwater), and electrical system. As a general rule, inspect anodes every 3-6 months and plan to replace them at least annually. Engines kept in saltwater may require more frequent changes.

Why is this anode made of zinc?

Zinc is the standard material for anodes used in saltwater environments. It is less noble than the aluminum alloys used in your outboard's lower unit, meaning it will corrode first, sacrificing itself to protect more critical and expensive components.

Does this anode help with steering?

Yes. In addition to preventing corrosion, this part functions as a trim tab. It can be adjusted to counteract propeller torque, which causes the boat to pull in one direction. Proper adjustment creates more neutral, easier handling.

Is this an OEM part or aftermarket?

This listing is an aftermarket replacement (not OEM). It is built to OEM-level specifications with comparable materials. All parts are manufactured in an ISO 9002 facility and batch-inspected for quality and consistency.
