Complete Crankshaft Assembly for Sea-Doo Challenger / SE 1 x 260 1503

This complete crankshaft assembly is a direct-fit replacement engine component for Sea-Doo Challenger and SE 260 1503 models, restoring the rotating assembly that delivers the power your 2012 4-stroke marine engine relies on.

Overview

This complete crankshaft assembly serves as the rotating core of the 1503 4-stroke engine used in the Sea-Doo Challenger and SE 260. When a crank is scored or worn, engine smoothness and output suffer, so this assembly is built to bring balance and durability back to the bottom end. It suits riders, mechanics, and rebuilders reviving the 260-horsepower platform from the 2012 model year.
