Good To Know

Q: How do I know this gasket fits my watercraft? A: Match the OEM number 6BH-14749-00-00 against the part listed for your machine and confirm your model year falls in the 2010-2020 SX 240 HO range.

Q: Should I replace the gasket every time the muffler comes off? A: Yes, exhaust gaskets crush to seal and generally should not be reused once the joint is opened, since a spent gasket can leak or rattle.
