Specs At A Glance

Good To Know

Q: Do I need to replace this gasket every time the throttle body is removed? A: Yes, a throttle body gasket is a single-use seal, and reusing a compressed gasket risks an air leak. Fit a fresh gasket whenever the throttle body is pulled.

Q: How do I know if this gasket fits my watercraft? A: Match your model year and engine to the listing and confirm your existing part number is 420950792. Serial number differences can affect fit, so verify 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.
