Installation Notes

  1. Disconnect the battery and ensure the engine is secure. Drain the gearcase oil into a suitable container.
  2. Remove the propeller and any related hardware.
  3. Unbolt and carefully remove the lower unit (gearcase) from the outboard's midsection.
  4. Disassemble the driveshaft and gear assembly to access the old thrust bearing. Note the order and orientation of all components.
  5. Remove the worn bearing and clean the housing area of any debris or contaminants.
  6. Install the new thrust bearing, ensuring it is properly seated.
  7. Reassemble the driveshaft, gears, and seals in reverse order, applying marine grease where specified by the service manual.
  8. Reinstall the lower unit, refill with fresh gearcase oil, and attach the propeller.
  9. Before full operation, test the engine at low RPMs in the water to check for proper shifting and to detect any leaks.

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.

What is the difference between OEM vs. Aftermarket?

This listing is an aftermarket replacement (not OEM). It's built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, it's batch-inspected for consistency.

How fast is shipping?

We ship worldwide quickly—typical transit is 5–15 days. Standard shipping is free; expedited options appear at checkout where available.

What is the warranty and return policy?

This part is covered by a 1-year warranty against manufacturing defects under normal use. If issues arise, contact support with your order details. Returns are accepted within our standard window for unused items in original condition. See our policy page or reach out for instructions.
