Good To Know

Q: Can this bearing go in without checking clearances? A: No, main bearing clearances should always be measured with plastigauge or a micrometer before final torque. Skipping that step risks premature failure.

Q: Is this an original Sea-Doo component? A: No, this is an aftermarket crankshaft main bearing for the listed Sea-Doo application. Verify your engine code and serial before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
