Good To Know

Q: How do I know if my throttle body gasket needs replacing? A: A hardened, cracked, or leaking gasket often causes erratic idle, lean running, or a whistle at the intake. Replace it whenever the throttle body is removed.

Q: Is this an original Sea-Doo part? A: This is an aftermarket replacement part designed to fit Sea-Doo applications and cross-references OEM 420950792. Confirm 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.
