420256606 Valve Seat Sleeve for Sea-Doo GTR P STD 230 1503 2018

Valve Seat Sleeve for Sea-Doo

This valve seat sleeve, reference 420256606, is a replacement engine component that press-fits into the cylinder head to give the intake and exhaust valves a durable seating surface on your Marine engine.

Overview

This valve seat sleeve for Sea-Doo is a press-in engine component that restores the seating surface where the valves seal against the cylinder head. A worn or dropped seat causes compression loss and poor running, so replacing the valve seat sleeve brings sealing geometry back to spec. It is aimed at riders and shops rebuilding 1503 series Marine engines.
