Good To Know

Q: Does this gasket fit both 760 and 500 Wave Runner models? A: This listing covers the 1989-1993 500 Wave Runner; check the separate 760 listing for later models. Always confirm your model and year before ordering.

Q: Should I replace the gasket every time the exhaust is opened? A: Exhaust gaskets are typically single-use and should be replaced once the joint is disturbed. Reusing a compressed gasket can lead to leaks.

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