This belt drives engine-mounted accessories such as the alternator and water circulation components, keeping charging and cooling systems running as the engine designer intended. Choosing the correct belt part number for your specific engine serial number range matters because MerCruiser revised belt specifications across production runs, and an incorrect belt can slip, wear prematurely, or fail to properly tension accessory drives.\u003c\/p\u003e\u003cp\u003eThis part number is confirmed for the MerCruiser 8.2L MIE (502 cid, 8-cylinder, 4-barrel) built within serial numbers C878221 through D857199, and for the MerCruiser 8.2L MPI MIE (502 cid, 8-cylinder, 4-barrel) built within serial numbers K147350 through K999999. Boat owners and marine technicians can use the engine serial number stamped on the block to confirm this belt is the correct match before ordering, since MerCruiser used different belt part numbers across other serial ranges on these same engine families.\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 18-15290\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e V-Belt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.18 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999566256\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMerCruiser 8.2L MIE (502 cid, 8-cylinder, 4-barrel), serial numbers C878221-D857199, 1990-1993\u003c\/li\u003e\n\u003cli\u003eMerCruiser 8.2L MPI MIE (502 cid, 8-cylinder, 4-barrel), serial numbers K147350-K999999, 1997\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-15290 V-belt fit?\u003c\/strong\u003e The Sierra 18-15290 fits the MerCruiser 8.2L MIE (502 cid, 8-cylinder, 4-barrel) built within serial numbers C878221-D857199, and the MerCruiser 8.2L MPI MIE (502 cid, 8-cylinder, 4-barrel) built within serial numbers K147350-K999999.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if 18-15290 is the right belt for my MerCruiser 8.2L engine?\u003c\/strong\u003e Check the engine serial number stamped on the block against the ranges C878221-D857199 (8.2L MIE) or K147350-K999999 (8.2L MPI MIE); if your engine falls in one of those ranges, the Sierra 18-15290 is the correct belt.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat years does the Sierra 18-15290 V-belt cover?\u003c\/strong\u003e This belt covers MerCruiser 8.2L MIE engines from 1990-1993 and MerCruiser 8.2L MPI MIE engines from 1997, based on the serial number ranges for those production years.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-15290 V-belt weigh?\u003c\/strong\u003e The Sierra 18-15290 V-belt weighs 0.18 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-15290 a genuine Sierra part?\u003c\/strong\u003e Yes, 18-15290 is a Sierra brand V-belt manufactured for marine applications, not a generic aftermarket substitute.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does the 18-15290 V-belt drive on the engine?\u003c\/strong\u003e On the MerCruiser 8.2L MIE and 8.2L MPI MIE engines it fits, this V-belt drives engine-mounted accessories such as the alternator and cooling components.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes 18-15290 fit other MerCruiser 8.2L engine variants?\u003c\/strong\u003e No, 18-15290 is specified only for the 8.2L MIE (serial numbers C878221-D857199) and 8.2L MPI MIE (serial numbers K147350-K999999); other 8.2L serial ranges use different Sierra belt part numbers.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-15290 V-belt?\u003c\/strong\u003e The UPC for the Sierra 18-15290 V-belt is 030999566256.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I install the Sierra 18-15290 V-belt myself?\u003c\/strong\u003e The 18-15290 is a standard accessory drive V-belt that can be installed using typical belt tensioning and replacement procedures for MerCruiser 8.2L MIE and 8.2L MPI MIE engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy does the engine serial number matter for ordering this belt?\u003c\/strong\u003e MerCruiser 8.2L engines went through multiple belt specification changes across production, so the Sierra 18-15290 is matched to specific serial number ranges (C878221-D857199 for 8.2L MIE, K147350-K999999 for 8.2L MPI MIE) rather than fitting all 8.2L engines.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988088238299,"sku":"SIE-18-15290","price":18.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-15290__82607.1737844508.500.750.jpg?v=1785329189","url":"https:\/\/www.goodvibesmarina.com\/products\/mercruiser-v-belt-29-in-replaces-57-13457-57-53215-18-15290","provider":"Good Vibes Marina","version":"1.0","type":"link"}
