Complete Crankshaft Assembly for Sea-Doo GTX STD NA 1503

This complete crankshaft assembly is a replacement rotating core for the 1503 engine used in the Sea-Doo GTX STD NA, restoring the crank that turns piston motion into the drive that spins the jet pump.

Overview

This complete crankshaft assembly is intended for the Sea-Doo GTX STD NA running the 1503 engine, giving owners a full rotating core instead of a bare crank. The crankshaft assembly converts combustion force from the connecting rods into rotational output that drives the jet pump, which is why it sits at the center of any bottom-end rebuild. It suits riders and shops working on GTX STD NA craft from 2007 through 2019 that need a fresh crank on the bench.

• Machined journals sized to accept the 1503 connecting rods and bearings
• Balanced crank throws aimed at smooth running across the rpm range
• Pressed-together design matching the 1503 engine platform layout
• Built to handle the sustained load of jet pump propulsion
