Sierra Valve Cover Gasket Replaces Yamaha Gaskets & Seals

Sierra valve cover gaskets are replacement valve cover gaskets (also called rocker cover gaskets) for Yamaha outboard engines. Each one is designed to replace the original Yamaha gasket. It seals the joint between the valve cover and the cylinder head.

Key Features:

• Seals the valve cover to the cylinder head to keep engine oil in and contaminants out
• Aftermarket replacement for the corresponding Yamaha OEM gasket
• Made by Sierra, a long-established supplier of marine engine replacement parts
• Each variant lists the Yamaha OEM part number it replaces

Replacing a worn, hardened or leaking valve cover gasket helps stop oil seepage and keeps the engine's top end sealed. Choose the variant whose listing matches the Yamaha OEM part number you need.
