It seals the connection between the exhaust manifold riser and the manifold spacer, helping maintain a tight, leak-free joint that keeps exhaust gases and cooling water properly routed away from the engine. This gasket is matched to installations built around the 18-1906 manifold spacer paired with either the 18-1971 or 18-1978 exhaust riser, and it is one of the elbow gaskets found in the 18-8554 mounting kit configuration. At 0.042 pounds, it is a light, low-cost wear item that is typically replaced whenever the riser or manifold spacer is removed for service, since reusing an old gasket can lead to exhaust or water leaks at the joint. Boat owners servicing a Mercruiser exhaust system with this riser\/spacer combination can use the 27-00524 gasket to restore a proper seal without needing to source the original Mercury part number. Always confirm your exhaust assembly matches the 18-1906 spacer and 18-1971\/18-1978 riser configuration before ordering, since exhaust manifold gaskets are not universal across all riser and spacer combinations.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e EMP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 27-00524\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Category:\u003c\/strong\u003e Mercruiser Exhaust Manifolds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.042 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 840080434155\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 18-0897\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Manifold Spacer:\u003c\/strong\u003e 18-1906\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Exhaust Risers:\u003c\/strong\u003e 18-1971, 18-1978\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Mounting Kit:\u003c\/strong\u003e 18-8554\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManifold Spacer 18-1906\u003c\/li\u003e\n\u003cli\u003eExhaust Riser 18-1971\u003c\/li\u003e\n\u003cli\u003eExhaust Riser 18-1978\u003c\/li\u003e\n\u003cli\u003eMounting Kit 18-8554\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e18-0897\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the EMP 27-00524 exhaust riser gasket replace?\u003c\/strong\u003e This gasket replaces Mercury part number 18-0897, an elbow gasket used in Mercruiser exhaust manifold assemblies.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich risers is the 27-00524 gasket designed to work with?\u003c\/strong\u003e It is designed for use with the 18-1971 and 18-1978 exhaust manifold risers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this gasket work with the 18-1906 manifold spacer?\u003c\/strong\u003e Yes, the EMP 27-00524 gasket is intended for use alongside the 18-1906 manifold spacer during riser installation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this gasket part of a mounting kit?\u003c\/strong\u003e The 18-0897 gasket that the 27-00524 replaces is one of the elbow gaskets included in the 18-8554 mounting kit configuration.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 27-00524 exhaust riser gasket weigh?\u003c\/strong\u003e It weighs 0.042 pounds, making it a lightweight component for exhaust manifold servicing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for this gasket?\u003c\/strong\u003e UPC 840080434155 identifies the EMP 27-00524 exhaust riser gasket.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 27-00524 gasket an OEM or aftermarket part?\u003c\/strong\u003e It is manufactured by EMP as a direct-fit replacement for the Mercury 18-0897 elbow gasket, not an original Mercury part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat category of engine does this gasket fit?\u003c\/strong\u003e The 27-00524 gasket is categorized for Mercruiser exhaust manifold applications.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I use this gasket with just one riser, or does it need both 18-1971 and 18-1978?\u003c\/strong\u003e The 27-00524 gasket works with either the 18-1971 or the 18-1978 riser, since both use the same 18-0897 gasket it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat should I check before ordering the 27-00524 gasket?\u003c\/strong\u003e Confirm your exhaust assembly uses the 18-1906 manifold spacer with an 18-1971 or 18-1978 riser, since the 27-00524 gasket is matched to that configuration.\u003c\/p\u003e","brand":"EMP","offers":[{"title":"Default Title","offer_id":48991283708123,"sku":"EMP-27-00524","price":5.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/EMP_27-00524_Exhaust_Riser_Gasket__88971.1722356512.500.750.jpg?v=1785329103","url":"https:\/\/www.goodvibesmarina.com\/products\/marine-exhaust-riser-elbow-gasket-for-mercruiser-replaces-18-0897-fits-manifolds-18-1958-1-18-1962-1-with-risers-18-1971-18-1978","provider":"Good Vibes Marina","version":"1.0","type":"link"}
