Good To Know

Q: Is this retainer an original Sea-Doo part? A: No, it is an aftermarket replacement made for Sea-Doo 1503 engine applications. It is not an original brand product.

Q: Can I reuse my old retainer? A: Retainers wear and can lose their grip on the valve stem, so replacing them during a rebuild is good practice. Confirm the part matches your engine before ordering.

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