Intake/Exhaust Valve Spring Retainer for Sea-Doo

This intake/exhaust valve spring retainer keeps valve springs positively located in the 1503 engine so the valvetrain stays stable at high rpm.

Overview

This intake/exhaust valve spring retainer is a replacement valvetrain component for the 1503 four-stroke engine. It holds each valve spring in its seat so the spring can control valve motion through the full rpm range, making it a practical service part for rebuilds and top-end repairs.

Specs At A Glance

Good To Know

Q: Do I need to replace all retainers at once? A: It is good practice to inspect every retainer when the head is off and replace any that show wear, cracks, or distortion. Matching wear across the set keeps valvetrain behavior consistent.

Q: Can this be installed with basic hand tools? A: Retainer installation requires a valve spring compressor to release and reseat the springs safely. Torque and clearance specs should be followed from the service manual for the 1503 engine.

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