Good To Know

Q: Do I need to replace all main bearings at once? A: If one crankshaft main bearing shows scoring or wear, the others often do too, so replacing the full set during a rebuild is common practice. Always measure journal clearances before reassembly.

Q: Is this an original Sea-Doo part? A: This is an aftermarket replacement crankshaft main bearing for Sea-Doo applications, not an original factory component. Confirm the part number against your machine's parts diagram 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.
