Good To Know

Q: Is this an original Sea-Doo part? A: No, it is an aftermarket gasket built to replace OEM part 420950792. It is not manufactured or endorsed by Sea-Doo.

Q: Should the gasket be replaced every time the throttle body comes off? A: Yes, a fresh gasket is recommended each time the throttle body is removed to maintain a leak-free seal. Reusing a compressed gasket can let air bypass the throttle body.

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