Good To Know

Q: Is this an original Sea-Doo part? A: This is a replacement valve spring retainer made for Sea-Doo applications, not an original factory part. Confirm the part number against your machine before ordering.

Q: Do I need to replace retainers when changing valve springs? A: Retainers are often replaced alongside valve springs during a top-end service to keep the valvetrain reliable. Inspect your existing retainers for wear or damage first.
