Good To Know

Q: Should all main bearings be replaced together? A: During a rebuild it is common to replace the complete set, since wear typically develops across the assembly. Check each bearing position first.

Q: Is this an original Sea-Doo bearing? A: No, this is an aftermarket crankshaft main bearing made for Sea-Doo applications. Verify the position and measurements you need 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.
