It is built to meet or exceed original equipment quality, giving it the fit and sealing performance of the factory gasket it replaces. This gasket restores a proper air-tight seal at the air silencer mounting point, which is essential for correct carburetor airflow and preventing intake leaks that can cause rough running or hard starting.\u003c\/p\u003e\u003cp\u003eAs a low-cost, frequently replaced maintenance part, the 18-0933 is typically installed whenever the air silencer is removed for carburetor service, cleaning, or general outboard maintenance. Its round shape and OEM-equivalent construction make it a direct swap for the original Johnson\/Evinrude gasket, and it is sold individually for a single air silencer location.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-0933\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Evinrude Outboard Gasket Sets\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape:\u003c\/strong\u003e Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999755414\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible With:\u003c\/strong\u003e Johnson\/Evinrude Outboard Motor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross-Reference:\u003c\/strong\u003e 314115\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eJohnson\/Evinrude Outboard Motor (air silencer to carburetor location)\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e314115\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-0933 gasket fit?\u003c\/strong\u003e The Sierra 18-0933 Air Silencer Gasket is designed for Johnson\/Evinrude outboard motors, sealing the air silencer to the carburetor intake.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does the 18-0933 replace?\u003c\/strong\u003e It replaces OEM number 314115, so any listing that references 314115 for a Johnson\/Evinrude air silencer gasket corresponds to the Sierra 18-0933.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-0933 an OEM-equivalent gasket?\u003c\/strong\u003e Yes, the 18-0933 is built to meet or exceed original equipment quality, making it a direct equivalent to the factory Johnson\/Evinrude air silencer gasket.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat shape is the 18-0933 gasket?\u003c\/strong\u003e The 18-0933 Air Silencer Gasket is round in shape, matching the mounting flange of the air silencer it seals.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-0933 gasket weigh?\u003c\/strong\u003e The Sierra 18-0933 weighs 0.1 pounds, consistent with its use as a thin sealing gasket rather than a structural component.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen should I replace the air silencer gasket?\u003c\/strong\u003e Replace the 18-0933 any time the air silencer is removed for carburetor cleaning or service, since gaskets should not be reused once broken loose from their seal.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order the 18-0933?\u003c\/strong\u003e Each order includes one Sierra 18-0933 Air Silencer Gasket for a single air silencer location on a Johnson\/Evinrude outboard motor.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the UPC 030999755414 match the Sierra 18-0933?\u003c\/strong\u003e Yes, UPC 030999755414 is the identifier for the Sierra 18-0933 Air Silencer Gasket.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I install the 18-0933 myself?\u003c\/strong\u003e Yes, the 18-0933 is a straightforward drop-in gasket that installs at the air silencer to carburetor joint during routine outboard maintenance.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-0933 a genuine Sierra part or aftermarket?\u003c\/strong\u003e The 18-0933 is a genuine Sierra part manufactured to meet or exceed original equipment specifications for Johnson\/Evinrude outboard motors.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988086403291,"sku":"SIE-18-0933","price":4.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-0933_lg__93983.1558120209.500.750.jpg?v=1785188793","url":"https:\/\/www.goodvibesmarina.com\/products\/air-silencer-gasket-oem-314115-for-johnson-evinrude-outboards-sierra-18-0933","provider":"Good Vibes Marina","version":"1.0","type":"link"}
