1503 Complete Crankshaft Assembly for Sea-Doo Challenger S/C 215 2006-2009

Complete Crankshaft Assembly for Sea-Doo Challenger S/C 215 1503

This complete crankshaft assembly is a direct-fit replacement for the Sea-Doo Challenger S/C 215 1503 engine, restoring the core rotating assembly that converts piston motion into drive power for the supercharged 4-TEC platform.

Overview

This complete crankshaft assembly is built for the Sea-Doo Challenger S/C 215 1503, covering 2006 through 2009 model years of the supercharged 1503 4-TEC engine. The crankshaft assembly handles the heavy lifting inside the engine, carrying the connecting rods and transferring combustion force into the rotation that drives the impeller. It suits rebuilders, shops, and owners who need a fresh lower-end foundation rather than a salvaged core.

Specs At A Glance

Good To Know

Q: Is this an original Sea-Doo part? A: This is an aftermarket complete crankshaft assembly made to fit Sea-Doo Challenger S/C 215 1503 engines, not an original factory part. Always confirm your engine code and model year before ordering.

Q: Can I reuse my old bearings with this crankshaft? A: New bearings matched to the machined journal sizes are strongly recommended during any lower-end rebuild. Measure clearances and verify the assembly spins freely before final assembly.

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