Installation Notes

Installation should be performed by a qualified marine mechanic. Begin by disconnecting the battery and ensuring the engine is cool. Remove components obstructing access to the intake manifold. Carefully detach the manifold, noting bolt positions. Thoroughly clean both the cylinder head and manifold mating surfaces, removing all traces of old gasket material and debris. Position the new gasket correctly, reinstall the manifold, and tighten bolts to the manufacturer-specified torque and sequence to ensure a proper, leak-free seal.

Troubleshooting & FAQ

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

This gasket fits Johnson/Evinrude 3-cylinder outboards with 50, 60, or 70 HP ratings from 1974 and newer. The most reliable way to confirm fitment is by matching your old part's OEM number to the ones listed: 0317307, 326926, or 0326926. Also, visually compare your old gasket to our product images.

What are the signs of a failed intake gasket?

Common symptoms include a rough or high idle, poor engine performance, reduced power, audible vacuum leak sounds (hissing), or engine backfiring. A visual inspection may also reveal cracks or visible deterioration on the old gasket.

Is any sealant required with this gasket?

Generally, this gasket is designed to be installed dry. However, always consult your engine's service manual. Some mechanics may apply a very thin layer of non-hardening sealant to assist with positioning and sealing, but it is not typically required if mating surfaces are clean and true.

How often should an intake gasket be replaced?

Intake gaskets do not have a fixed replacement interval. They should be replaced whenever the intake manifold is removed for service, or if you diagnose symptoms of a leak or failure. They are a wear item that can degrade over time due to heat cycles and exposure to fuel.

What is the main difference between this part and an OEM one?

This is an aftermarket part designed to meet or exceed original equipment manufacturer (OEM) specifications for fit, form, and function. It provides comparable performance and sealing capability at a more accessible price point.

OEM vs. Aftermarket?

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
