It seals the exhaust leg to prevent water intrusion and exhaust leakage at the joint, helping protect surrounding components from corrosion and heat damage caused by a failed seal. The seal is molded from rubber in a round shape and finished in white.\u003c\/p\u003e\u003cp\u003eSierra manufactures this seal to meet or exceed the quality of the original equipment part it replaces, making it a reliable choice when servicing the exhaust leg on compatible OMC Cobra sterndrive units. Replacing a worn or cracked exhaust leg seal at the first sign of deterioration helps avoid water entering the exhaust system and prevents more costly repairs down the line. Each unit is sold individually and is straightforward to install as part of a routine exhaust leg service.\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 18-0540\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Exhaust Leg Rubber Seal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Rubber\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\u003eWeight:\u003c\/strong\u003e 0.05 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999874481\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eOMC Cobra sterndrive applications\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e320936\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-0540 used for?\u003c\/strong\u003e The Sierra 18-0540 is a rubber seal that fits on the exhaust leg of an OMC Cobra sterndrive, sealing the joint to prevent water and exhaust leakage.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-0540 seal replace OEM part 320936?\u003c\/strong\u003e Yes, the Sierra 18-0540 Exhaust Leg Rubber Seal replaces OEM part number 320936 and is built to meet or exceed the quality of the original part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 18-0540 exhaust leg seal made from?\u003c\/strong\u003e It is made from rubber, molded in a round shape, and finished in white.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-0540 seal weigh?\u003c\/strong\u003e The Sierra 18-0540 Exhaust Leg Rubber Seal weighs 0.05 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Sierra 18-0540 seal?\u003c\/strong\u003e This exhaust leg seal is white.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-0540 an OEM or aftermarket part?\u003c\/strong\u003e The 18-0540 is a Sierra aftermarket replacement seal manufactured to meet or exceed the specifications of the original equipment part it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many seals come in a package of the 18-0540?\u003c\/strong\u003e The 18-0540 Exhaust Leg Rubber Seal is sold as a single unit count of one.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat boats or engines use the 18-0540 exhaust leg seal?\u003c\/strong\u003e The 18-0540 is designed for OMC Cobra sterndrive applications where an exhaust leg rubber seal is required.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if my exhaust leg seal needs replacement?\u003c\/strong\u003e If the exhaust leg rubber seal on an OMC Cobra sterndrive is cracked, hardened, or leaking, it should be replaced with a seal such as the Sierra 18-0540 to prevent water intrusion into the exhaust system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-0540 seal?\u003c\/strong\u003e The UPC for the Sierra 18-0540 Exhaust Leg Rubber Seal is 030999874481.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988077162715,"sku":"SIE-18-0540","price":13.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-0540_lg__57578.1558119494.500.750.jpg?v=1785188611","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-0540-exhaust-leg-rubber-seal-replaces-omc-320936-omc-cobra-sterndrive","provider":"Good Vibes Marina","version":"1.0","type":"link"}
