Good To Know

Q: Is this an original Sea-Doo part? A: This is an aftermarket intake valve that cross-references part number 420855131, not an original brand component.

Q: Should I replace all valves at once? A: It is often wise to inspect and replace related valvetrain components together when doing a top-end service to keep wear consistent.
