Jet Pump Assembly for Sea-Doo

This jet pump assembly is a complete propulsion unit that forces water through the impeller to push your watercraft forward, and it is built as a direct replacement for the factory pump on the Sea-Doo GTX STD 300 1630 platform.

Overview

This jet pump assembly is the full rear propulsion unit that drives water through the impeller housing to produce thrust for your personal watercraft. Built as a replacement for the Sea-Doo GTX STD 300 1630, it brings back factory-style water flow and acceleration when the original pump housing, wear ring, or stator is worn or damaged. It suits riders and shops handling a complete pump replacement on a 2021 to 2026 GTX STD 300 1630.

Specs At A Glance

Good To Know

Q: Is this a complete drop-in jet pump? A: Yes, it is a full jet pump assembly that replaces the unit on your 2021-2026 GTX STD 300 1630 as a complete package rather than individual components.

Q: Do I need to replace the impeller too? A: Only if the existing impeller shows nicks, bends, or excessive wear; a healthy impeller can be reused if it still meets clearance specs.

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