Good To Know

Q: Is this an original Sea-Doo part? A: No, this is a replacement valve spring retainer made for Sea-Doo 1503 platform engines and is not an OEM component.

Q: Do I need more than one? A: Valve spring retainers are typically replaced in sets during a top-end rebuild, so confirm the quantity your 1503 engine requires.

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