Troubleshooting & FAQ
How do I confirm this fits my Johnson/Evinrude engine?
Because this part fits many but not all models in the 125-175 HP range, the best way to confirm compatibility is to check your engine's service manual or existing part for the number 389455 or 0389455.
Is professional installation required?
Yes, we strongly recommend it. Installation involves disassembling the lower unit (gearcase), which requires specialized tools and expertise to ensure proper alignment, sealing, and function.
What are the symptoms of a bad bearing housing assembly?
Signs of failure include grinding noises from the lower unit, excessive driveshaft vibration, or metal shavings found in the gear lube. A visual inspection may also reveal cracks in the housing or seized bearings.
What is the recommended replacement interval for this part?
There is no fixed replacement interval. This component is typically replaced only when it fails. Regular lower unit gear lube changes and inspections will help identify potential issues early.
