Good To Know

Q: Is this an original Sea-Doo part? A: No, it is an aftermarket throttle body gasket made to match OEM 420950792. Always confirm your model and part number before ordering.

Q: Can I reuse the old gasket? A: Throttle body gaskets are generally single-use and should be replaced once the throttle body is removed. Reusing a compressed gasket risks an air leak.

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