It directs exhaust flow from the manifold to the connected exhaust hose at the correct angle for proper drainage and reliable engine cooling water discharge, replacing worn or corroded factory elbows that can leak exhaust or coolant.\u003c\/p\u003e\u003cp\u003eThis elbow is a direct cross-reference for Mercury Marine 44354A3 and 807914A1, so it installs as a like-for-like replacement without modification. It is finished in black and is designed to pair with the correct elbow gasket for a sealed connection at the manifold. Sierra recommends using elbow gasket 18-2849-1 or 18-0897 with this elbow, and the matching 18-8505 mounting kit (sold separately) includes an 18-0897 elbow gasket specifically for use with this riser.\u003c\/p\u003e\u003cp\u003eEach unit ships as a single elbow (1 pack), intended for engine and drive system repair and maintenance work where the original manifold elbow has failed or is due for preventive replacement.\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 18-1976-2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Manifold Elbow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHose Connection Size:\u003c\/strong\u003e 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAngle:\u003c\/strong\u003e 7 degree down angle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Manifold:\u003c\/strong\u003e 18-1953-2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Elbow Gaskets:\u003c\/strong\u003e 18-2849-1, 18-0897\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 25 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282325664\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePack Quantity:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Mercruiser Exhaust Manifolds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eFits Manifold: 18-1953-2\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercury Marine 44354A3\u003c\/li\u003e\n\u003cli\u003eMercury Marine 807914A1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-1976-2 manifold elbow fit?\u003c\/strong\u003e The 18-1976-2 manifold elbow is designed to fit the 18-1953-2 exhaust manifold.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs 18-1976-2 a direct replacement for Mercury Marine 44354A3?\u003c\/strong\u003e Yes, 18-1976-2 directly cross-references to Mercury Marine part numbers 44354A3 and 807914A1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat hose size does this elbow use?\u003c\/strong\u003e This manifold elbow is built for a 4 inch hose connection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat angle is the 18-1976-2 elbow?\u003c\/strong\u003e It is a 7 degree down angle elbow, distinct from other Sierra manifold elbows offered at different angles.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-1976-2 manifold elbow weigh?\u003c\/strong\u003e The Sierra 18-1976-2 manifold elbow weighs 25 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat gasket should be used with the 18-1976-2 elbow?\u003c\/strong\u003e Elbow gasket 18-2849-1 or 18-0897 is compatible with the 18-1976-2 manifold elbow; the 18-8505 mounting kit for this riser also includes an 18-0897 gasket.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-1976-2 elbow come with mounting hardware?\u003c\/strong\u003e No, the 18-1976-2 is the elbow only; mounting hardware and gaskets are supplied separately in mounting kit 18-8505.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Sierra 18-1976-2 manifold elbow?\u003c\/strong\u003e It is finished in black.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many elbows come in one order?\u003c\/strong\u003e Each order of the 18-1976-2 manifold elbow contains a single unit (1 pack).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-1976-2 elbow genuine OEM or aftermarket?\u003c\/strong\u003e The 18-1976-2 is a Sierra-manufactured aftermarket part engineered to replace Mercury Marine 44354A3 and 807914A1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the difference between 18-1976-2 and 18-1974-1?\u003c\/strong\u003e 18-1976-2 is a 4 inch hose, 7 degree down angle elbow for the 18-1953-2 manifold, while 18-1974-1 is a 3 inch hose, 0 degree down angle elbow for the same manifold; they use different mounting kits and are not interchangeable.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988089680091,"sku":"SIE-18-1976-2","price":208.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/sie-18-1976-2__30245.1727894429.500.750.jpg?v=1785189189","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-1976-2-manifold-exhaust-elbow-4in-hose-7-degree-down-angle-replaces-mercury-44354a3-fits-manifold-18-1957-2-mercruiser","provider":"Good Vibes Marina","version":"1.0","type":"link"}
