Troubleshooting & FAQ
How do I confirm this bearing is the right part for my motor?
Verify your engine's model and year against our compatibility table. The surest method is to match the part number (93316-003Y0) with the one in your engine's service manual or on the original part itself.
What are common signs of a failing lower unit bearing?
Symptoms often include a grinding or whining noise from the gearcase, excessive vibration felt through the tiller or hull, or finding metal shavings (especially large or numerous ones) in the gear oil during a change.
Is this a sealed bearing?
Given its placement in the lower casing drive assembly, this bearing is designed to be lubricated by the gearcase oil. It is not a self-contained, pre-greased sealed unit.
Can I install this bearing myself?
This repair requires specialized tools, such as a bearing press and pullers, to avoid damaging the component and housing. For a safe and reliable repair, professional installation is strongly recommended.
