OMC Johnson Evinrude NEW OEM Air Box Silencer Base 329611 V4 90 115 140HP 0810

Johnson / Evinrude OEM Air Box Silencer Base — Part Number 329611
Brand: Johnson / Evinrude / OMC | Condition: New Old Stock (NOS)

You are purchasing a genuine Johnson/Evinrude OEM Air Box Silencer Base, part number 329611 (also 0329611), for Johnson and Evinrude V4 2-stroke outboard motors. The air box silencer base is the lower mounting plate of the air silencer/attenuator assembly — it provides the foundation for the air intake silencer that reduces intake noise and filters incoming air to the carburetors on V4 outboard engines. A cracked, broken, or missing silencer base can allow unfiltered air into the carburetor system, affecting engine performance, fuel mixture, and intake noise levels. This is an authentic factory original part — never installed, never used.

Condition Details: This is a New Old Stock (NOS) part. The air box silencer base itself is in new, uninstalled condition. As is common with NOS inventory, the original packaging may show signs of age, including shelf wear, dust, or minor cosmetic blemishes on the bag or box. The part is new and fully functional.
