It is manufactured as an all-new anodized aluminum casting rather than a remanufactured unit, eliminating the reliability concerns that come with rebuilding older red-cast carburetors after years of exposure to the harsh marine environment. Each unit is flow tested throughout its entire throttle range before it ships, and the fuel mixture and idle settings are preset from the factory, so installation typically requires only minor idle and choke adjustments.\u003c\/p\u003e\u003cp\u003eThe 18-7370N carburetor meets or exceeds OEM specifications and is designed to bolt directly in place of the original equipment carburetor on applicable 1998-2004 MCM 5.0L engines. A base gasket is included with the carburetor for installation; Sierra specifies replacement gasket 18-0994 for future gasket service on this 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 18-7370N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Carburetor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e 1998-2004 MCM 5.0L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e New anodized aluminum casting (non-remanufactured)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Machined\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Type:\u003c\/strong\u003e Gasoline\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange Type:\u003c\/strong\u003e Bolt On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGasket:\u003c\/strong\u003e Base gasket included; use replacement gasket 18-0994 for future service\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 4.41 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282339906\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e1998-2004 MCM 5.0L\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e3310-864942A01\u003c\/li\u003e\n\u003cli\u003e3310-861448A1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-7370N carburetor fit?\u003c\/strong\u003e The 18-7370N is built for 1998-2004 MCM 5.0L marine engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does the 18-7370N replace?\u003c\/strong\u003e It replaces OEM carburetors numbered 3310-864942A01 and 3310-861448A1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a remanufactured or new carburetor?\u003c\/strong\u003e The 18-7370N is a completely new anodized aluminum casting, not a remanufactured unit, which avoids the durability issues common with rebuilt red-cast carburetors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-7370N come with a gasket?\u003c\/strong\u003e Yes, a base gasket is included with the 18-7370N carburetor at installation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat gasket should I use if I need a replacement later?\u003c\/strong\u003e For future gasket service on the 18-7370N, Sierra specifies replacement gasket 18-0994.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-7370N carburetor weigh?\u003c\/strong\u003e The 18-7370N carburetor weighs 4.41 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAre the fuel mixture and idle settings preset on the 18-7370N?\u003c\/strong\u003e Yes, the fuel mixture and idle settings on the 18-7370N are preset at the factory, so only minor idle and choke adjustments are typically needed after installation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-7370N tested before it ships?\u003c\/strong\u003e Each 18-7370N carburetor is flow tested throughout its entire throttle range before leaving the factory.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the flange type on this carburetor?\u003c\/strong\u003e The 18-7370N uses a bolt-on flange type.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-7370N meet OEM specifications?\u003c\/strong\u003e The 18-7370N meets or exceeds OEM specifications for the 1998-2004 MCM 5.0L application it is built for.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat finish does the 18-7370N carburetor have?\u003c\/strong\u003e The 18-7370N has a machined finish on its anodized aluminum casting.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988384493787,"sku":"SIE-18-7370N","price":340.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-7370N__12097.1753214488.500.750.jpg?v=1785188061","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-7370n-marine-carburetor-for-mercruiser-120-2-5l-140-3-0l-inboard-engines-replaces-3310-860070a2-base-gasket-included","provider":"Good Vibes Marina","version":"1.0","type":"link"}
