  3. Remove the bolts securing the lower unit (gearcase) to the engine's midsection and carefully lower it.
  4. Following your engine's service manual, disassemble the gearcase to access the transmission components and locate the old bearing.
  5. Use appropriate bearing pullers to remove the worn bearing from its housing.
  6. Clean the bearing seat thoroughly, ensuring it is free of debris or burrs.
  7. Press the new bearing into place evenly, making sure it is fully seated.
  8. Reassemble the gearcase components, replacing any seals or gaskets as recommended by the service manual.
  9. Reinstall the lower unit, torquing the bolts to the specified values.
  10. Refill the gearcase with the correct type and amount of marine gear lubricant.
  11. Reinstall the drain/fill screws with new gaskets and test the engine's shifting and operation in a safe environment.

Troubleshooting & FAQ

How do I confirm this bearing fits my exact engine model?

The best way is to cross-reference the OEM part number from your engine's service manual or parts diagram. If it matches 09263-25062, 09269-25014 (for Suzuki), or 5031258 (for Johnson/Evinrude), this part is a compatible replacement. You can also check the detailed compatibility table.

Where is this bearing installed?

This bearing is located inside the gearcase, also known as the lower unit. It is a critical part of the transmission assembly that supports rotational components like the driveshaft or propshaft.

What are the signs of a failing transmission bearing?

Common symptoms include a grinding or whining noise from the lower unit, excessive vibration during operation, difficulty shifting gears, or finding metal shavings in the gearcase oil during a fluid change.

How often should this part be replaced?

There is no fixed replacement interval for this bearing. It should be inspected whenever the gearcase is serviced and replaced if there are any signs of wear, noise, roughness when turning, or damage.

Why does the Johnson/Evinrude compatibility list "Various" models?

Over the years, Johnson/Evinrude used Suzuki-built 4-stroke powerheads on some of their models. This bearing fits those specific 40-50 HP models made between 1999-2006. Due to branding variations, it's most reliable to confirm fitment using the OEM part number 5031258 rather than by a specific model name.

What is the difference between this and the OEM part?

This is an aftermarket part designed to meet or exceed OEM specifications for fit, form, and function. It offers a cost-effective solution without compromising on quality, using comparable materials and manufacturing processes.

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.
