420254882 Intake or Exhaust Valve Guide for Sea-Doo RXT SCIC 1503 2007

Intake or Exhaust Valve Guide for Sea-Doo

This intake or exhaust valve guide is a replacement engine component for Sea-Doo watercraft, referenced under OEM part number 420254882, designed to hold the valve in precise alignment as it opens and closes.

Overview

This valve guide serves as a direct-fit replacement for the 1503 SCIC engine found in Sea-Doo RXT models. As a valve guide, it keeps each valve moving true against the seat, which protects compression and reduces oil seepage past the stem. It suits riders and mechanics rebuilding or refreshing a 2007 RXT SCIC top end.

Good To Know

Q: Does this fit both the intake and exhaust side? A: Yes, this guide is listed for either intake or exhaust valve service on the 1503 SCIC. Confirm the position you are rebuilding before ordering.

Q: Is machine work required to install it? A: Valve guides are typically pressed in and then reamed to final clearance, so a machine shop is recommended. Verify the bore spec for your head before fitting.

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