The riser directs exhaust gases and cooling water away from the manifold and out through the exhaust elbow, and is engineered to the same fit and function as the original Mercury Marine 12076A2 riser it replaces.\u003c\/p\u003e\u003cp\u003eThis riser is designed for use with Sierra manifolds 18-1954-1, 18-1955-1, and 18-1956-3. A complete installation calls for the matching elbow gasket (18-2819-1), the 18-8551 mounting hardware kit (which includes only the hardware for this elbow), and the 18-2748 exhaust boot to complete a sealed exhaust path. The riser is finished in white and weighs 18.35 pounds as shipped.\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 18-1975-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Manifold Riser with Exhaust Tube\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 12076A2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 18.35 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUsed With Manifolds:\u003c\/strong\u003e 18-1954-1, 18-1955-1, 18-1956-3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElbow Gasket:\u003c\/strong\u003e 18-2819-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Hardware:\u003c\/strong\u003e 18-8551\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExhaust Boot:\u003c\/strong\u003e 18-2748\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282186470\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercury Marine \/ Mercruiser late model 4 cylinder engines\u003c\/li\u003e\n\u003cli\u003eMCM 2.5L and 3.0L\/LX, 1982 and newer\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMercury Marine 12076A2\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-1975-1 replace?\u003c\/strong\u003e The Sierra 18-1975-1 manifold riser is a direct replacement for Mercury Marine OEM part 12076A2.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich engines is this riser designed for?\u003c\/strong\u003e This riser fits late model Mercruiser 4 cylinder engines, specifically the MCM 2.5L and 3.0L\/LX, 1982 and newer.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-1975-1 riser weigh?\u003c\/strong\u003e The Sierra 18-1975-1 manifold riser weighs 18.35 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the 18-1975-1 manifold riser?\u003c\/strong\u003e It ships finished in white.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich manifolds does the 18-1975-1 work with?\u003c\/strong\u003e This riser is designed for use with Sierra manifolds 18-1954-1, 18-1955-1, and 18-1956-3.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat gasket do I need with the 18-1975-1 riser?\u003c\/strong\u003e Use elbow gasket 18-2819-1 with the Sierra 18-1975-1 manifold riser.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-1975-1 come with mounting hardware?\u003c\/strong\u003e No, mounting hardware is sold separately as hardware kit 18-8551, which includes only the hardware needed for the 18-1975-1 elbow.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs an exhaust boot required with this riser?\u003c\/strong\u003e Yes, the 18-2748 exhaust boot is used to complete the sealed exhaust path with the 18-1975-1 riser.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-1975-1 genuine Sierra or aftermarket?\u003c\/strong\u003e It is a genuine Sierra part, manufactured as an aftermarket replacement equivalent to Mercury Marine 12076A2.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included with the 18-1975-1 riser?\u003c\/strong\u003e The listing includes one Sierra 18-1975-1 riser with exhaust tube; the elbow gasket, mounting hardware, and exhaust boot are separate part numbers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-1975-1 fit older Mercruiser engines before 1982?\u003c\/strong\u003e Fitment for the Sierra 18-1975-1 is confirmed for MCM 2.5L and 3.0L\/LX engines from 1982 and newer; earlier engines are not confirmed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat warranty applies to the Sierra 18-1975-1?\u003c\/strong\u003e The 18-1975-1 is covered under Sierra's standard customer satisfaction warranty, as with all Sierra parts.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988089516251,"sku":"SIE-18-1975-1","price":281.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-1975-1__37458.1737888203.500.750.jpg?v=1785188675","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-1975-1-exhaust-manifold-riser-with-tube-replaces-mercury-12076a2-fits-mercruiser-2-5l-and-3-0l-lx-4-cylinder-1982-and-newer","provider":"Good Vibes Marina","version":"1.0","type":"link"}
