Throttle Body Gasket for Sea-Doo

This throttle body gasket is a direct-fit replacement seal for the Sea-Doo GTX S 155 1503, offered as an OEM cross-reference for 420950792, designed to seat between the throttle body and intake to prevent air leaks.

Overview

This Throttle Body Gasket for Sea-Doo is a precision-cut sealing component that stops unmetered air from leaking past the throttle body mounting surface on the GTX S 155 1503. A worn or hardened gasket on this throttle body gasket application can cause lean running, rough idle, and hesitation, so replacing it restores a clean, consistent seal. It is intended for riders and mechanics servicing 2012, 2013, and 2015 Sea-Doo GTX S 155 models.

Specs At A Glance

Good To Know

Q: Is this an original Sea-Doo part? A: No, this is an aftermarket throttle body gasket that cross-references OEM number 420950792. It is not manufactured by Sea-Doo.

Q: Should I replace it every time the throttle body is removed? A: Replacing the gasket whenever the throttle body is unbolted is good practice, since a reused gasket may not reseal properly. Confirm the part number matches your model year before ordering.

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