Installation Notes

Disconnect the battery and ensure the engine is cool. Disconnect fuel lines and any electrical connections attached to the intake manifold.
Carefully remove the intake manifold assembly from the engine block.
Remove the old gasket and thoroughly clean both mounting surfaces on the crankcase and the intake manifold. Ensure no old gasket material, sealant, or debris remains.
Position the new gasket, making sure all bolt holes and ports align perfectly. Do not use any sealant unless explicitly required by the engine's service manual.
Reinstall the intake manifold, tightening the bolts in the sequence and to the torque specifications recommended by the manufacturer to ensure an even seal.
Reconnect all fuel lines, sensors, and electrical connections before reconnecting the battery.

Troubleshooting & FAQ

How do I confirm this gasket fits my specific engine model?

This gasket is designed for Johnson/Evinrude V6 Crossflow engines from 150-235 HP. The most reliable method of confirmation is to match your old part number to 329718 or the superseded number 321198. Always visually compare the new gasket to your old one before installation.

What are common signs of a failed intake manifold gasket?

Symptoms of a bad gasket include a rough idle, engine misfires, decreased power, stalling, or a noticeable hissing sound from the engine bay due to a vacuum leak. You may also see a "check engine" light with codes related to a lean fuel mixture.

Do I need to use sealant with this gasket?

In most cases, this gasket is designed to be installed dry. Using gasket sealant or RTV can interfere with a proper seal and may not be necessary. Always follow the specific instructions in your engine's official service manual.

What is the difference between this V6 Crossflow gasket and others?

Engine gaskets are not interchangeable. This gasket is specifically cut and designed for the port and bolt pattern of the Johnson/Evinrude V6 Crossflow engine architecture. Using an incorrect gasket will result in vacuum leaks, poor performance, and potential engine damage.
