Good To Know

Q: How many main bearings does this engine use? A: The Sea-Doo 1503 engine uses multiple main bearings along the crankshaft, so confirm the quantity needed for your rebuild before ordering. Q: Can I install this without machining the crankcase? A: In most cases yes, but the crankshaft journals and bearing clearances should be measured to confirm they are within spec.

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