This kit brings together the ignition components needed to perform a complete tune-up in one package, restoring reliable spark and smooth engine performance without having to source individual parts separately. It is built to replace the OEM 898253T28 ignition kit, giving boat owners and marine technicians a straightforward, single-part-number solution for scheduled maintenance or ignition troubleshooting.\u003c\/p\u003e\u003cp\u003eKeeping ignition components fresh is critical on marine engines, where exposure to moisture and vibration accelerates wear on distributor caps, rotors, and related ignition parts. Using a complete tune-up kit rather than mixing components from multiple sources helps ensure proper fit and consistent quality across all the included parts. The Sierra 18-5246 is intended specifically for late model V-6, 4.3L engines equipped with Alpha or Bravo sterndrives, so confirming this engine and drive combination before ordering is recommended.\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 18-5246\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Tune Up Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.79 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282167578\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e Tune Up Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaces (OEM):\u003c\/strong\u003e 898253T28\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eLate model V-6, 4.3L (Alpha\/Bravo)\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e898253T28\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines is the Sierra 18-5246 tune up kit designed for?\u003c\/strong\u003e This kit is designed for late model V-6, 4.3L engines with Alpha or Bravo sterndrives.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part number does the Sierra 18-5246 replace?\u003c\/strong\u003e It replaces OEM part number 898253T28.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-5246 kit a genuine Sierra part or aftermarket?\u003c\/strong\u003e The 18-5246 is manufactured by Sierra as a direct-fit ignition tune-up kit, sold under Sierra's own part number rather than as a generic aftermarket substitute.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the tune up kit weigh?\u003c\/strong\u003e The Sierra 18-5246 tune up kit weighs 0.79 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the 18-5246 kit?\u003c\/strong\u003e It is white.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill this kit fit a V-8 sterndrive engine?\u003c\/strong\u003e No. The 18-5246 is specified for late model V-6, 4.3L Alpha\/Bravo engines; V-8 applications use a different Sierra part number.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included in the Sierra 18-5246 kit?\u003c\/strong\u003e The package includes a tune up kit sized and configured for the late model V-6, 4.3L Alpha\/Bravo engine application.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I use OEM number 898253T28 to look up this kit?\u003c\/strong\u003e Yes, 898253T28 is the OEM cross-reference number for the Sierra 18-5246 tune up kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this kit work with both Alpha and Bravo drives?\u003c\/strong\u003e Yes, the 18-5246 is designated for late model V-6, 4.3L engines paired with either Alpha or Bravo sterndrives.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-5246?\u003c\/strong\u003e The UPC for this tune up kit is 808282167578.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988202729691,"sku":"SIE-18-5246","price":90.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-5246_lg__31599.1558127912.500.750.jpg?v=1785188507","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-5246-tune-up-kit-for-mercruiser-4-3l-v-6-alpha-bravo-replaces-898253t28","provider":"Good Vibes Marina","version":"1.0","type":"link"}
