Good To Know

Q: Do I need to replace this gasket every time the throttle body is removed? A: Yes, gaskets are single-use sealing components and should be replaced any time the throttle body is unbolted to ensure a proper seal. Reusing an old gasket can lead to vacuum leaks.

Q: Can I install this gasket myself? A: This gasket installs with basic hand tools once the throttle body is accessed, making it a manageable job for someone comfortable working on personal watercraft. Tighten fasteners evenly to avoid distorting the flange.

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