Troubleshooting & FAQ
How do I know if this gasket fits my engine?
Confirm your model and horsepower using the compatibility table. This gasket is specifically for Mercruiser 35 HP & 55 HP models and OMC/Johnson/Evinrude 35-55 HP models, cross-referencing part numbers REC330909 and 330910/0330910.
What are the signs of a failing air silencer gasket?
Symptoms of a bad gasket include a hissing sound from the engine, rough idling, poor acceleration, or engine stalling. These issues are caused by unmetered air entering the intake system, leaning out the fuel/air mixture.
Can I reuse my old gasket?
No. Gaskets are designed for single use. They compress and deform to create a seal and will not seal properly if reused, leading to air leaks and poor engine performance.
What is the difference between this aftermarket part and an OEM one?
This part is manufactured to meet or exceed original equipment manufacturer (OEM) specifications for fit, form, and function. It offers comparable performance and material quality at a better value.
How often should this gasket be replaced?
Replace the gasket whenever the air silencer or carburetor is removed for service. It should also be inspected for brittleness or damage during routine maintenance and replaced as needed.
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.
