Description

The Intake Manifold Gasket 335633 is an OEM replacement sealing gasket used on select OMC, Johnson and Evinrude 2-cylinder loop-charged outboard engines.

The intake manifold gasket creates a seal between the intake manifold and adjoining engine components, helping maintain proper airflow and crankcase sealing. A worn, damaged, or deteriorated gasket can contribute to air leaks, poor engine performance, inconsistent running, or difficulty maintaining proper fuel and air delivery.

Replacing the intake manifold gasket is recommended whenever the intake manifold is removed for service or when an air leak or gasket failure is suspected.

Installation & Fitment

Whenever the intake manifold is removed, inspect the gasket and sealing surfaces before reassembly. A damaged, compressed, torn, or deteriorated gasket should be replaced to help ensure a proper seal.

Johnson and Evinrude used multiple engine configurations and intake designs across different model years, so always verify your engine model number and/or original OEM part number before ordering.
