Good To Know

Q: Does this exhaust gasket require any sealant during installation? A: Follow the manufacturer procedure for your engine, as most exhaust gaskets of this type install dry and rely on the gasket material itself to seal. Inspect the mating surfaces for flatness before installing.

Q: How often should an exhaust gasket be replaced? A: Replacement is typically done whenever the exhaust joint is opened or when signs of leaking, such as soot tracking or a change in exhaust note, appear. Keeping a spare on hand is common for regular PWC maintenance.

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