Troubleshooting & FAQ
How can I confirm this bearing is the right part for my motor?
The best way is to cross-reference the part number stamped on your original bearing. This part replaces Yamaha 93332-00001-00 and Parsun PAT40-04000027. Also, check the compatibility table to ensure your engine model (F50 or F60) is listed.
What are common symptoms of a worn vertical shaft bearing?
Signs of a failing bearing include a grinding or whining noise from the lower unit, excessive vibration during operation, or noticeable play (looseness) in the driveshaft. If you notice these symptoms, inspect the bearing promptly to avoid further damage.
How is this aftermarket bearing different from the OEM version?
This part is engineered to meet or exceed original equipment manufacturer (OEM) specifications for fit, form, and function. It is made from comparable marine-grade materials to ensure reliable performance and corrosion resistance in marine environments.
Is any special grease required during installation?
Yes, always use a high-quality marine-grade grease that is water-resistant and suitable for bearings under load. Consult your engine's service manual for the recommended type of grease for lower unit components.
