Throttle Body Gasket for Sea-Doo

This throttle body gasket seals the connection between the throttle body and intake for Sea-Doo personal watercraft and jet boats, and it is a direct replacement carrying OEM cross-reference 420950792.

Overview

This throttle body gasket for Sea-Doo keeps a positive seal at the throttle body mounting surface so the engine draws unmetered air only where it should. That seal on this throttle body gasket prevents vacuum leaks that cause rough idle, lean running, and poor throttle response. It is a maintenance item for owners servicing the intake tract on their Sea-Doo watercraft.

Good To Know

Q: Why replace a throttle body gasket? A: Gaskets compress and harden over time, and a worn seal lets air leak past the throttle body, causing rough idle or lean running. Replacing it restores the intended seal on reassembly.

Q: Is this an original Sea-Doo part? A: This is a replacement gasket cross-referenced to OEM number 420950792, not an original factory-branded part. Confirm it matches your model and serial number 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.
