Jet Pump Assembly for Sea-Doo GTX 155 1503 2009 2013

Jet Pump Assembly for Sea-Doo

This complete jet pump assembly is the propulsion unit for the Sea-Doo GTX 155 1503, converting engine power into thrust through the impeller housing, wear ring, and stator vane assembly.

Overview

This jet pump assembly is a complete propulsion unit built for the Sea-Doo GTX 155 1503 personal watercraft. It moves water through the housing to create forward thrust, delivering the acceleration and top-end response riders expect from the GTX 155 platform. This jet pump assembly is the right choice for replacing a worn, damaged, or failing pump on your machine.

Built For Performance

• Complete assembly with impeller housing ready for installation
• Stator vanes straighten water flow for efficient thrust output
• Wear ring positioned to maintain proper impeller clearance
• Durable housing construction built to withstand continuous water exposure
• Direct fitment for the 1503 engine platform in the GTX 155

Fits These Machines

• for Sea-Doo GTX 155 1503 (2009)
• for Sea-Doo GTX 155 1503 (2013)

On-The-Job Use

• Replacing a damaged or clogged jet pump on the GTX 155
• Restoring thrust and acceleration after impeller wear
• Routine driveline maintenance on 1503-equipped watercraft
• Repairing pumps damaged by debris ingestion

Good To Know

Q: What does a jet pump assembly do on a Sea-Doo? A: It draws water in through the intake and forces it out the nozzle to create thrust, which drives the watercraft forward. A worn pump can cause cavitation, vibration, or loss of top speed.

Q: Should the wear ring be checked when replacing the pump? A: Yes, the wear ring clearance directly affects thrust efficiency, so inspect it during installation. Excessive clearance can cause cavitation even with a new pump.

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