Troubleshooting & FAQ
How can I confirm this bearing fits my exact Yamaha motor?
Check the ID plate on your motor's clamp bracket for the model code (e.g., E40GMH) and serial number. Compare this with the models listed in the compatibility table. Verifying the OEM part number (93315-217U0) in your service manual is the most reliable method.
What are the symptoms of a failing intermediate shaft bearing?
Common signs include a whining or grinding noise from the lower unit, excessive vibration that changes with engine RPM, or finding fine metal shavings in the gearcase oil during a change. Prompt inspection is recommended if these symptoms appear.
Is a special tool required for installation?
Yes, due to its press-fit design, a bearing driver set or a hydraulic press is required for safe removal of the old bearing and installation of the new one without causing damage to the component or gearcase housing.
