Good To Know

Q: How many main bearings does my engine need? A: That depends on your specific 1503cc Sea-Doo crankshaft layout, so check your service manual for the total count before ordering. Many rebuilds replace all main bearings as a set.

Q: Can I install this myself? A: Bearing installation requires precise measurement of oil clearance and proper crank alignment. If you do not have the tools or experience, a qualified PWC mechanic should handle the job.

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