Troubleshooting & FAQ
How do I know if this wrist pin bearing fits my Yamaha outboard?
This bearing fits specific Yamaha 200-300 HP 6-cylinder, 76-degree V-block engines from 1990-2010. Please consult the "Engine & Model Compatibility" table and cross-reference your engine model and year to ensure a perfect match.
What are the signs of a failing wrist pin bearing?
Common symptoms include a distinct knocking or rattling sound from the engine, especially under load or at certain RPMs. You may also notice a loss of power or increased engine vibration. Accurate diagnosis requires engine inspection.
Is a special tool required for installation?

How often should wrist pin bearings be replaced?
