Troubleshooting & FAQ
How do I know if this bearing fits my specific Yamaha outboard?
Verify your engine against the models listed in the Engine & Model Compatibility table. This bearing is specifically for Yamaha V6 3.1L and 3.2L standard rotation outboards (200HP, 225HP, 250HP) from 1990–2006. Cross-reference the OEM part number 93306-210U0-00 to confirm.
What are the signs of a failing reverse gear bearing?
Common symptoms include grinding, whining, or humming noises from the lower unit, especially when in gear. You may also notice excessive vibration during operation or find metal shavings in the gear lube during a change.
Is a special tool required for installation?
Yes, replacing internal gearcase components like this bearing requires specialized tools. A bearing puller and a press are necessary for proper removal and installation without damaging the housing or the new part.
What kind of grease or lubricant should I use?
This bearing is lubricated by the gearcase oil. Use a high-quality marine gear lubricant that meets your engine manufacturer's specifications (e.g., API GL-5). Do not pack the bearing with grease separately.
