Complete Crankshaft Assembly for Sea-Doo GTS 130

This complete crankshaft assembly is a direct replacement component for the Sea-Doo GTS 130 1503 engine, restoring the rotating core that converts piston motion into the drive that turns the impeller.

Overview

This complete crankshaft assembly is manufactured for the Sea-Doo GTS 130 and 1503 engine platform, serving as the central rotating component that ties the connecting rods to the PTO and magneto ends of the powerplant. Riders and shops rebuilding a 1503 engine choose a complete crankshaft assembly when the original journals, bearings, or rod surfaces are worn beyond reuse. It suits the 2011 through 2014 and 2016 GTS 130 models listed, making it a strong choice for a full bottom-end refresh.

Specs At A Glance

Good To Know

Q: Does this crankshaft assembly come with connecting rods? A: A complete crankshaft assembly is sold with the rods already fitted to the crank, which simplifies installation during a bottom-end rebuild.

Q: Should I replace bearings at the same time? A: Replacing main and rod bearings alongside a new crankshaft assembly is standard practice, since worn bearings can quickly damage fresh crank journals.

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