Good To Know

Q: Is this an original Sea-Doo part? A: No, this is an aftermarket power valve cover made to fit the listed Sea-Doo applications and cross-references OEM number 420911558.

Q: Do I need to replace the gasket too? A: A fresh gasket is recommended whenever the cover is removed, since old gaskets often tear or harden and can cause exhaust leaks.
