Troubleshooting & FAQ
How can I confirm this bearing fits my specific Yamaha model?
The best method is to cross-reference your engine's model and year against the compatibility table above. You can also verify the OEM part number stamped on your old bearing; if it is 93315-314V8-00, this part is a direct replacement.
What are the signs of a failed driver shaft bearing?
Common symptoms include a grinding or whining noise from the lower unit, excessive vibration during operation, or the presence of metal shavings (a "metallic slurry") in the gearcase oil during a change. These signs indicate it's time to inspect the internal components.
Is there a recommended replacement interval for this bearing?
There is no fixed replacement interval; the bearing is designed to last for many years under normal operating conditions. It should be inspected whenever the lower unit is serviced and replaced if any signs of wear, corrosion, or damage are found.
