It is designed as a direct cross-reference for Mercury Marine part 27-810846T, giving boat owners and marine technicians a reliable option when the oil pan needs to come off for service, inspection, or repair. The gasket is finished in white and is sold as a single unit, ready to install without additional trimming or fabrication.\u003c\/p\u003e\u003cp\u003eA properly sealed oil pan gasket is essential to keeping engine oil contained and preventing leaks that can lead to low oil pressure, fouled bilges, or contamination of other engine components. The Sierra 18-1239 is built to the fit and dimensions of the engine oil pan it is designed for, so it seats correctly against the mating surfaces during reassembly. Because it carries a limited warranty, it is intended as a dependable replacement part rather than a universal or trimmable gasket.\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 18-1239\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Oil Pan Gasket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.4 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282242954\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGTIN:\u003c\/strong\u003e 00808282242954\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 27-810846T\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e OMC 3.0L, 3.0L\/LX\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits OMC 3.0L and 3.0L\/LX engines.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cp\u003e27-810846T (Mercury Marine)\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-1239 oil pan gasket fit?\u003c\/strong\u003e The Sierra 18-1239 fits OMC 3.0L and 3.0L\/LX engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-1239 the same as Mercury Marine 27-810846T?\u003c\/strong\u003e Yes, the Sierra 18-1239 is a direct cross-reference for Mercury Marine part number 27-810846T.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Sierra 18-1239 oil pan gasket?\u003c\/strong\u003e It is white, matching the finish used on this Sierra oil pan gasket.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-1239 weigh?\u003c\/strong\u003e The Sierra 18-1239 oil pan gasket weighs 0.4 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many gaskets come in a package of the Sierra 18-1239?\u003c\/strong\u003e Each package of the Sierra 18-1239 contains one oil pan gasket, sold as a single unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sierra 18-1239 come with a warranty?\u003c\/strong\u003e Yes, the Sierra 18-1239 oil pan gasket is backed by a limited warranty.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I use the Sierra 18-1239 as a genuine equivalent to the Mercury Marine part?\u003c\/strong\u003e The Sierra 18-1239 is manufactured as a cross-reference replacement for Mercury Marine 27-810846T, intended to fit and seal in the same application.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-1239 oil pan gasket?\u003c\/strong\u003e The UPC for the Sierra 18-1239 is 808282242954.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the Sierra 18-1239 fit a 3.0L\/LX engine specifically?\u003c\/strong\u003e Yes, the 3.0L\/LX designation is one of the two fitments listed for the Sierra 18-1239 oil pan gasket, alongside the OMC 3.0L.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen would I need to replace the oil pan gasket on my OMC 3.0L engine?\u003c\/strong\u003e An oil pan gasket like the Sierra 18-1239 typically needs replacement when the pan is removed for service or when it shows signs of an oil leak at the pan mating surface.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988087288027,"sku":"SIE-18-1239","price":107.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-1239_lg__55738.1558119640.500.750.jpg?v=1785188048","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-1239-oil-pan-gasket-replaces-mercruiser-27-810846t-fits-3-0l-gm-181-mercruiser-omc-volvo-penta","provider":"Good Vibes Marina","version":"1.0","type":"link"}
