Good To Know

Q: Should main bearings be replaced as a set? A: Many builders replace all main bearings at once so wear stays even across the crank, so consider matching this bearing with the rest of your set. A: Always measure journal clearances before final assembly.

Q: Is this an original Sea-Doo part? A: No, this is an aftermarket crankshaft main bearing made for the listed Sea-Doo application. Confirm 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.
