Troubleshooting & FAQ
How can I confirm this bearing fits my engine?
Your model should be listed in the compatibility table. The most reliable method is to cross-reference the OEM part number (93311-832U4-00) with your engine's parts diagram or existing bearing.
What are the signs of a failing crankshaft bearing?
Common symptoms include a knocking or rumbling noise from the engine, increased vibration, the presence of metal shavings in the engine oil, and a loss of performance. Immediate inspection is recommended if you notice these signs.
Is this a "big end" or "small end" bearing?
This is a big end bearing, which fits on the crankshaft journal where the connecting rod attaches.
Why is the P6 precision rating important?
The P6 rating indicates a higher level of precision and tighter manufacturing tolerances than standard bearings. This is critical for high-RPM engine applications, ensuring proper fit, reduced vibration, and longer service life.
Can I install this bearing myself?
This is an internal engine component that requires significant disassembly. Professional installation by a qualified marine mechanic is strongly recommended to ensure correct fitment, safety, and engine longevity.
