This gasket forms the critical seal at this junction, helping prevent water intrusion and gear lubricant leaks where the drive shaft housing bolts to the bell housing. Replacing this gasket is a standard step any time the drive shaft housing or bell housing is removed for service, inspection, or outdrive repair, since the original gasket material is not reusable once disturbed.\u003c\/p\u003e\u003cp\u003eSierra manufactures this gasket as a direct-fit replacement carrying OEM cross-reference 27-54014, so it installs in place of the factory gasket without modification. Keeping a fresh gasket on hand for this application is good practice for any owner performing outdrive maintenance, as a compromised seal at this joint can allow water into the housing or lubricant to leak out, leading to corrosion or gear damage over time.\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 18-2847\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDescription:\u003c\/strong\u003e Drive Shaft Housing to Bell Housing Gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Mercruiser Bell Housing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 27-54014\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999313553\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eThis gasket is intended for the drive shaft housing to bell housing joint on Mercruiser outdrive assemblies.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e27-54014\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-2847 gasket used for?\u003c\/strong\u003e It seals the joint between the drive shaft housing and the bell housing on a Mercruiser outdrive, preventing water and lubricant leaks at that connection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does the 18-2847 replace?\u003c\/strong\u003e Sierra part 18-2847 cross-references to OEM number 27-54014.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does this gasket weigh?\u003c\/strong\u003e The Sierra 18-2847 drive shaft housing to bell housing gasket weighs 0.1 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this gasket reusable after removal?\u003c\/strong\u003e No. Like most housing gaskets, the 18-2847 should be replaced with a new one any time the drive shaft housing or bell housing is disassembled, since a used gasket will not reseal reliably.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere on the outdrive does this gasket install?\u003c\/strong\u003e It fits at the mating surface where the drive shaft housing bolts to the bell housing on the outdrive.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this gasket fit outdrives other than Mercruiser?\u003c\/strong\u003e The 18-2847 is designated for the bell housing application on Mercruiser outdrives; no other manufacturer fitment is specified for this part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for Sierra part 18-2847?\u003c\/strong\u003e The UPC for the Sierra 18-2847 gasket is 030999313553.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs Sierra 18-2847 a genuine Sierra part?\u003c\/strong\u003e Yes, 18-2847 is a Sierra-manufactured gasket built as a direct equivalent to OEM number 27-54014.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need any other gaskets when replacing this one?\u003c\/strong\u003e That depends on what else is being serviced at the same time; the 18-2847 itself covers only the drive shaft housing to bell housing joint, so other seals at the housing should be inspected separately.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy would this gasket need replacing?\u003c\/strong\u003e A leaking or deteriorated gasket at the drive shaft housing to bell housing joint can let water into the outdrive or allow lubricant to seep out, so the 18-2847 is replaced whenever that seal is compromised or the housing is opened for service.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988131754203,"sku":"SIE-18-2847","price":14.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-2847_lg__42459.1558123059.500.750.jpg?v=1785329157","url":"https:\/\/www.goodvibesmarina.com\/products\/mercruiser-cover-gasket-replaces-27-55810-sierra-18-2847-pack-of-2","provider":"Good Vibes Marina","version":"1.0","type":"link"}
