Troubleshooting & FAQ
How do I know if this bearing fits my exact engine model?
The surest way is to check your engine's model number and year against the compatibility table in this listing. If your model is listed, the part is a confirmed fit. Do not rely on horsepower alone.
What are the signs of a failing lower driveshaft bearing?
Common symptoms include a grinding or whining noise from the gearcase, excessive vibration, or visible metal shavings in the gear lube during an oil change. These signs indicate it's time to inspect internal components like this bearing.
Is this bearing difficult to replace?
This is considered an advanced repair. It requires draining the lower unit, removing the gearcase, and disassembling the driveshaft assembly. We strongly recommend professional installation unless you have significant experience with outboard motor repair.
What is the difference between this and the upper driveshaft bearing?
This is the lower driveshaft thrust bearing, located inside the gearcase assembly. The upper driveshaft bearing is typically located higher up, where the driveshaft enters the engine powerhead. They are not interchangeable.
OEM vs. Aftermarket?
This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
