Match both the manifold gasket reference (27-33395) and the elbow-joint gasket reference (27-41813) individually against your installed exhaust hardware.\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv style=\"margin:0;padding:18px 0;border-bottom:1px solid #dce3dc;\"\u003e\n      \u003ch3 style=\"margin:0 0 10px;color:#234d40;font-size:17px;line-height:1.5;font-weight:700;\"\u003eAre open, restrictor, and block-off elbow gaskets interchangeable?\u003c\/h3\u003e\n      \u003cp style=\"margin:0 0 14px;\"\u003eNo. Elbow-joint gaskets control water passage flow between the manifold and elbow. Among the cross-references listed for this set, Sierra 18-0897 is identified as a restrictor-type exhaust elbow gasket. An open (full-flow) or block-off gasket should not be substituted where a restrictor gasket is specified, and vice versa.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/section\u003e\n\u003c\/div\u003e","brand":"Serdamarine","offers":[{"title":"Default Title","offer_id":45165066190899,"sku":"24MFK134","price":32.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0699\/2930\/4115\/files\/marine-exhaust-part-7a48a1edbfa2349d.jpg?v=1792734198"}],"url":"https:\/\/serdamarine.com\/collections\/mercruiser-5-0l-mie-4-bbl-230-mie-4-bbl-inboard-0b522506-thru-0b788151-wet-joint-raw-water-cooling-exhaust-manifold-and-exhaust-elbow.oembed","provider":"我的商店","version":"1.0","type":"link"}
