This gasket is a direct cross-reference for OEM number 27-67751, making it a straightforward replacement when servicing the carburetor mounting surface. As a mounting gasket, it is designed to create a reliable, uniform seal against the mating surfaces of the carburetor base and manifold, restoring proper compression and preventing unmetered air from entering the fuel\/air mixture. Replacing a worn or hardened carburetor mounting gasket is a routine step whenever the carburetor is removed for cleaning, rebuilding, or replacement, and using the correct gasket helps avoid vacuum leaks that are difficult to diagnose once the carburetor is reinstalled. The Sierra 18-2509 is lightweight and sized specifically for this mounting application.\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 18-2509\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Carburetor Mounting Gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999312068\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.04 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e27-67751\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-2509 gasket fit?\u003c\/strong\u003e The Sierra 18-2509 is a carburetor mounting gasket that seals the carburetor to the intake manifold.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-2509 a direct replacement for OEM 27-67751?\u003c\/strong\u003e Yes, the Sierra 18-2509 carburetor mounting gasket directly cross-references to OEM number 27-67751.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-2509 carburetor mounting gasket weigh?\u003c\/strong\u003e It weighs 0.04 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen should I replace the carburetor mounting gasket?\u003c\/strong\u003e Replace the Sierra 18-2509 whenever the carburetor is removed for cleaning, rebuilding, or replacement, or if you notice a vacuum leak, rough idle, or hard starting caused by a worn or hardened gasket.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat happens if the carburetor mounting gasket fails?\u003c\/strong\u003e A failed carburetor mounting gasket, such as the Sierra 18-2509, allows unmetered air into the fuel\/air mixture, which can cause a lean-running condition, rough idle, or difficulty starting.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-2509 gasket?\u003c\/strong\u003e The UPC for the Sierra 18-2509 carburetor mounting gasket is 030999312068.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this gasket be reused after removal?\u003c\/strong\u003e No, the Sierra 18-2509 carburetor mounting gasket should be replaced with a new one any time the carburetor is removed, since gaskets do not reseal reliably once disturbed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-2509 an OEM or aftermarket gasket?\u003c\/strong\u003e The Sierra 18-2509 is an aftermarket gasket manufactured to cross-reference and replace OEM part 27-67751.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order the 18-2509?\u003c\/strong\u003e Ordering the Sierra 18-2509 includes one carburetor mounting gasket.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-2509 require any additional sealant?\u003c\/strong\u003e The dossier does not specify a sealant requirement for the 18-2509 carburetor mounting gasket; follow your engine manufacturer's service instructions for installation.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988106784987,"sku":"SIE-18-2509","price":1.49,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-2509_lg__29538.1558123071.500.750.jpg?v=1785329153","url":"https:\/\/www.goodvibesmarina.com\/products\/carburetor-mounting-gasket-27-67751-for-mercury-outboards","provider":"Good Vibes Marina","version":"1.0","type":"link"}
