Troubleshooting & FAQ
How do I confirm this bearing fits my engine?
Verify your engine's model, year, and horsepower against the compatibility tables on this page. For absolute certainty, cross-reference your existing part number with those listed in the 'Part Number Matrix'.
What are the signs of a failing lower unit bearing?
Common symptoms include a grinding or whining noise from the gearcase, excessive vibration, or the presence of metal shavings in the gear lube when it's changed. These indicate internal wear and require immediate inspection.
How often should this bearing be inspected or replaced?
This bearing is not a routine service item but should be inspected for play or roughness whenever the lower unit is disassembled for other service, such as water pump or seal replacement. Replace it if any damage or wear is detected.
Can I install this bearing myself?
Installation requires disassembly of the outboard's lower unit and the use of specialized tools like a bearing press. While possible for experienced mechanics, we recommend professional installation to ensure proper fitment and prevent damage.
