Good To Know

Q: Why replace a throttle body gasket? A: Gaskets harden and lose their sealing ability over time, letting air leak past the throttle body and causing rough idle or lean running. A fresh gasket restores the proper 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 the part number and model fitment 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.
