Troubleshooting & FAQ
How do I confirm this fits my specific Yamaha model?
The most reliable method is to match your engine's model number and year against our compatibility table. You can also verify by cross-referencing your existing part number with 67F-45331-00-CA or the superseded number 67F-45331-00-94.
Does this housing include the inner bearing and seals?
No, this part is the bearing housing (or carrier) only. The required bearings, seals, and o-rings must be purchased separately to complete the installation.
What are common signs of a failing bearing housing?
Symptoms of a bad bearing housing include excessive vibration from the lower unit, grinding or rattling noises during operation, or visible cracks and corrosion on the housing itself. Leaks from the propeller shaft seals are also a strong indicator of failure.
Can this part be used in saltwater?
Yes. This component is manufactured from marine-grade aluminum, which provides excellent corrosion resistance for use in both freshwater and saltwater environments.
Is installation difficult? Can I do it myself?
This repair is considered intermediate to advanced. It requires draining fluids, disassembling the lower unit, and correctly pressing in new seals. We recommend professional installation unless you have significant experience with outboard motor repair and the proper tools.
Is this a direct replacement for part 67F-45331-00-94?
Yes, this part is a direct replacement for Yamaha part number 67F-45331-00-94, which has been officially superseded by part number 67F-45331-00-CA.
