It is engineered as a direct replacement for the original equipment exhaust boot, sealing the connection point in the exhaust path to maintain a proper seal as exhaust gases exit the stern drive assembly. Each package includes one exhaust boot, making it a straightforward, single-part replacement for a worn, cracked, or deteriorated original boot.\u003c\/p\u003e\u003cp\u003eSierra states that each Sierra product meets or exceeds the original equipment part it replaces, and the 18-2745 is built to the fitment specifications of the OMC 912374 boot it is designed to replace. Because exhaust boots are fit specific, it is important to check part numbers against your stern drive's original component before ordering to ensure proper fit.\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 18-2745\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Exhaust Boot\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 4 x 4.75 x 4.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.88 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999752932\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity:\u003c\/strong\u003e 1 exhaust boot per package\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e OMC stern drive 5.7L \u0026amp; 7.5L (1986 \u0026amp; later)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e Replaces 912374\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eOMC stern drive, 5.7L \u0026amp; 7.5L, 1986 \u0026amp; later\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e912374\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-2745 Exhaust Boot fit?\u003c\/strong\u003e It is designed for OMC stern drives with 5.7L and 7.5L engines, model year 1986 and later.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does the 18-2745 replace?\u003c\/strong\u003e The Sierra 18-2745 Exhaust Boot replaces OMC part number 912374.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many exhaust boots come in a package?\u003c\/strong\u003e One exhaust boot is included per package of the Sierra 18-2745.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-2745 an OEM part or an aftermarket replacement?\u003c\/strong\u003e It is an aftermarket replacement manufactured by Sierra, built to meet or exceed the original equipment exhaust boot it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 18-2745 exhaust boot?\u003c\/strong\u003e The boot measures 4 x 4.75 x 4.75 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-2745 Exhaust Boot weigh?\u003c\/strong\u003e It weighs 0.88 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the 18-2745 fit any OMC stern drive engine size?\u003c\/strong\u003e No, this exhaust boot is fit specific and is designed for 5.7L and 7.5L OMC stern drive engines from 1986 and later, so part numbers should be checked against the original component before ordering.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-2745 Exhaust Boot?\u003c\/strong\u003e The UPC for the Sierra 18-2745 Exhaust Boot is 030999752932.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere is the exhaust boot installed on a stern drive?\u003c\/strong\u003e The 18-2745 exhaust boot is installed at the exhaust connection point on OMC stern drives with 5.7L and 7.5L engines to seal the exhaust path.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy replace a worn exhaust boot like the 18-2745?\u003c\/strong\u003e A cracked or deteriorated exhaust boot can leak, so replacing it with a properly fitted part like the Sierra 18-2745 helps maintain a sealed exhaust connection on compatible OMC stern drives.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes Sierra offer a warranty on the 18-2745 Exhaust Boot?\u003c\/strong\u003e Yes, the Sierra 18-2745 Exhaust Boot is covered by a limited warranty.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988109865179,"sku":"SIE-18-2745","price":34.7,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-2745_lg__48413.1558123991.500.750.jpg?v=1785188089","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-2745-exhaust-boot-for-omc-stern-drive-replaces-omc-912374-fits-5-7l-7-5l-1986-later","provider":"Good Vibes Marina","version":"1.0","type":"link"}
