Troubleshooting & FAQ
How do I know if this bearing fits my Yamaha outboard?
This bearing is designed for a wide range of Yamaha 200-300HP 4-stroke models from roughly 1990 to 2011 and beyond. The best way to confirm is to check your engine's specific model and year against the compatibility table on this page. If your model is listed, it will fit.
What are the signs of a failing driveshaft thrust bearing?
Common symptoms include a metallic grinding or whirring noise from the lower unit, excessive vibration that changes with engine RPM, or the presence of metal shavings when you change your gearcase oil. These signs indicate internal wear and suggest immediate inspection is needed.
Is this bearing difficult to install?
Installation requires disassembly of the lower unit (gearcase), which is a moderately complex task. You will need specific tools like a bearing puller and press, as well as a good understanding of the driveshaft assembly. Professional installation is highly recommended to ensure correct fitment and to avoid damage.
My outboard is a VMAX model. Will this part fit?
Yes, this part is compatible with several VMAX series models, such as the VZ200, VZ225, and VZ250, typically from the 2004–2011 model years. Always verify your specific model in our compatibility list or with your service manual.
Is this bearing for the upper or lower driveshaft?
This thrust bearing is installed in the lower unit/gearcase section of the outboard, where it supports the main driveshaft.
