It is designed as a direct replacement gasket for the Rochester 7044185 carburetor and is used as part of the Sierra 18-7075 replacement carburetor kit. This gasket meets or exceeds the quality of the original equipment part it replaces, giving installers a reliable seal without sourcing a full carburetor rebuild kit just to replace a worn or damaged gasket.\u003c\/p\u003e\u003cp\u003eBecause carburetor gaskets harden and lose their seal over time from heat cycling and exposure to fuel, replacing the mounting gasket is a routine step during carburetor service, rebuilds, or when troubleshooting a vacuum or fuel leak at the carburetor base. The 18-0434 is sold individually, making it a straightforward, low-cost fix when only the mounting gasket needs to be renewed. It carries the Sierra part number 18-0434 for easy reordering and cross-references directly to several original equipment part numbers used across outboard and marine engine applications.\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 18-0434\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Type:\u003c\/strong\u003e Carb Mounting Gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape:\u003c\/strong\u003e Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999873996\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.08 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelated Carburetor Kit:\u003c\/strong\u003e 18-7075 (for Rochester 7044185 carburetor)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eRochester 7044185 carburetor\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eGLM 31740\u003c\/li\u003e\n\u003cli\u003eEvinrude\/Johnson 909758\u003c\/li\u003e\n\u003cli\u003eOMC 909758\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-0434 used for?\u003c\/strong\u003e It is a carburetor mounting gasket that seals the joint between the carburetor and the intake manifold, sealing out air and fuel leaks at that connection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-0434 gasket cross-reference to any OEM numbers?\u003c\/strong\u003e Yes, the Sierra 18-0434 is interchangeable with GLM 31740, Evinrude\/Johnson 909758, and OMC 909758.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the OMC 909758 the same gasket as the Evinrude\/Johnson 909758?\u003c\/strong\u003e Yes, 909758 is listed as both an OMC and an Evinrude\/Johnson number, and the Sierra 18-0434 cross-references to it under both listings.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich carburetor does this gasket fit?\u003c\/strong\u003e The 18-0434 mounting gasket is used with the Rochester 7044185 carburetor and is included in the Sierra 18-7075 replacement carburetor kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-0434 gasket weigh?\u003c\/strong\u003e The Sierra 18-0434 carburetor mounting gasket weighs 0.08 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many gaskets come in a package?\u003c\/strong\u003e The Sierra 18-0434 is sold as a single gasket, with a unit count of 1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine Sierra part or a generic aftermarket copy?\u003c\/strong\u003e The 18-0434 is a genuine Sierra part, manufactured to meet or exceed the quality of the original equipment gasket it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need the full 18-7075 carburetor kit, or can I just buy the gasket?\u003c\/strong\u003e The mounting gasket is available on its own as the Sierra 18-0434, so you do not need to purchase the full 18-7075 carburetor kit if only the mounting gasket needs replacing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen should I replace this carburetor mounting gasket?\u003c\/strong\u003e Replace the 18-0434 gasket when it hardens, cracks, or no longer seals properly, which commonly shows up as a fuel or vacuum leak at the base of the carburetor.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-0434 gasket?\u003c\/strong\u003e The UPC for the Sierra 18-0434 carburetor mounting gasket is 030999873996.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988074246363,"sku":"SIE-18-0434","price":6.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-0434_lg__81552.1558118747.500.750.jpg?v=1785188573","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-0434-carburetor-mounting-gasket-replaces-omc-johnson-evinrude-909758-glm-31740-volvo-penta-mercruiser-rochester-carb","provider":"Good Vibes Marina","version":"1.0","type":"link"}
