It creates a reliable seal at the manifold joint, helping to prevent exhaust leaks and maintain proper engine performance. As a single-count component, this gasket is intended for straightforward replacement during routine maintenance or when servicing the exhaust manifold assembly. Its round shape and white finish are consistent with OEM-style manifold gaskets used in Volvo Penta exhaust manifold systems. At just 0.02 pounds, it is a lightweight, low-cost part that is easy to keep on hand as a spare for scheduled upkeep or unexpected repairs. Sierra manufactures this gasket to fit the exhaust manifold application it is designated for, making it a straightforward choice for boat owners and marine technicians replacing a worn or damaged manifold gasket. Always confirm the part number matches your existing gasket before ordering to ensure correct fitment.\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 18-2971-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Volvo Penta Exhaust Manifolds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape:\u003c\/strong\u003e Round\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 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282360238\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eDesignated for use in Volvo Penta exhaust manifold applications.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cp\u003eNo OEM cross-reference numbers are specified for this part.\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-2971-1?\u003c\/strong\u003e The Sierra 18-2971-1 is a round, white exhaust manifold gasket used to seal the exhaust manifold connection on applicable Volvo Penta marine engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat shape and color is this gasket?\u003c\/strong\u003e This gasket is round in shape and white in color, part number 18-2971-1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-2971-1 gasket weigh?\u003c\/strong\u003e It weighs 0.02 pounds, making it a lightweight component that is inexpensive to keep as a spare.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many gaskets come in one package?\u003c\/strong\u003e Each package of the Sierra 18-2971-1 contains a single gasket, listed as a unit count of 1.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat category of engine does this gasket belong to?\u003c\/strong\u003e The 18-2971-1 gasket is categorized under Volvo Penta exhaust manifolds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-2971-1 an OEM part or aftermarket?\u003c\/strong\u003e Sierra manufactures the 18-2971-1 as a replacement gasket for Volvo Penta exhaust manifold applications; no separate OEM cross-reference numbers are listed for it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for this part?\u003c\/strong\u003e The UPC for the Sierra 18-2971-1 exhaust manifold gasket is 808282360238.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen would I need to replace this gasket?\u003c\/strong\u003e The 18-2971-1 gasket should be replaced when servicing the exhaust manifold or if signs of an exhaust leak appear at the manifold joint.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-2971-1 gasket include any other hardware?\u003c\/strong\u003e The package includes only the exhaust manifold gasket itself, with no additional hardware included.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs installation of the 18-2971-1 gasket straightforward?\u003c\/strong\u003e Yes, replacing the exhaust manifold gasket is a standard maintenance task involving removal of the manifold and installation of the new gasket, part number 18-2971-1.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988135850203,"sku":"SIE-18-2971-1","price":14.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-2971-1__54250.1737862799.500.750.jpg?v=1785188289","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-2971-1-exhaust-elbow-gasket-for-volvo-penta-replaces-856039-3","provider":"Good Vibes Marina","version":"1.0","type":"link"}
