It is also correct for PleasureCraft MP 5.0L and 5.7L engine models from 2002-05. The rotor is a single-item component sold individually and mounts inside the distributor cap, transferring spark from the coil to the correct spark plug wire terminal in firing order as the distributor shaft rotates.\u003c\/p\u003e\u003cp\u003eThis is an OEM-equivalent part, cross-referencing to Mercury Marine 884790 and PleasureCraft R103011, so it installs and performs the same as the factory original without modification. Because ignition timing accuracy depends on a properly seated, correctly conducting rotor, replacing a worn, cracked, or corroded rotor at tune-up intervals helps maintain reliable spark delivery and smooth engine running. At 0.11 pounds, it is a compact, easy-to-handle service part suited for routine tune-up or distributor cap-and-rotor replacement jobs.\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 18-5245\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Distributor Rotor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDistributor Type:\u003c\/strong\u003e Delco HVS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e Mercury Marine 884790, PleasureCraft R103011\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282167561\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Items:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.11 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMerCruiser MCM\/MIE 4.3L, 5.0L, 5.7L \u0026amp; 6.2L MPI engines with ECM 555 S\/N 0M300000 \u0026amp; up, 2001 and newer\u003c\/li\u003e\n\u003cli\u003ePleasureCraft MP 5.0L and 5.7L models, 2002-05\u003c\/li\u003e\n\u003cli\u003eDelco HVS distributors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMercury Marine 884790\u003c\/li\u003e\n\u003cli\u003ePleasureCraft R103011\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-5245 rotor fit?\u003c\/strong\u003e The Sierra 18-5245 fits MerCruiser MCM\/MIE 4.3L, 5.0L, 5.7L, and 6.2L MPI engines built 2001 and newer with ECM 555 serial numbers 0M300000 and up, as well as PleasureCraft MP 5.0L and 5.7L engine models from 2002-05.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-5245 rotor an OEM part or an aftermarket equivalent?\u003c\/strong\u003e It is an aftermarket rotor built as a direct equivalent to Mercury Marine 884790 and PleasureCraft R103011, so it fits and functions the same as the original factory rotor.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this rotor cross-reference to Mercury Marine 884790?\u003c\/strong\u003e Yes, part number 18-5245 is the correct cross-reference for Mercury Marine 884790.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-5245 compatible with PleasureCraft R103011?\u003c\/strong\u003e Yes, the 18-5245 rotor is a direct match for PleasureCraft part R103011 on applicable MP 5.0L and 5.7L engines from 2002-05.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat distributor type does this rotor work with?\u003c\/strong\u003e The 18-5245 is designed for Delco HVS distributors used on the listed MerCruiser and PleasureCraft engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-5245 rotor weigh?\u003c\/strong\u003e The Sierra 18-5245 rotor weighs 0.11 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many rotors come in a package?\u003c\/strong\u003e The 18-5245 is sold as a single item, one rotor per package.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen should a distributor rotor like the 18-5245 be replaced?\u003c\/strong\u003e A distributor rotor should be replaced when it shows wear, cracking, or corrosion on the contact tip, typically during a tune-up alongside the distributor cap, to maintain consistent spark delivery on MerCruiser and PleasureCraft engines using Delco HVS distributors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-5245 fit MerCruiser engines older than 2001?\u003c\/strong\u003e No, the 18-5245 rotor is specified for MerCruiser MCM\/MIE 4.3L, 5.0L, 5.7L, and 6.2L MPI engines from 2001 and newer with ECM 555 serial numbers 0M300000 and up.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included with the Sierra 18-5245?\u003c\/strong\u003e Each order includes one Sierra 18-5245 distributor rotor.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988202893531,"sku":"SIE-18-5245","price":16.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-5245_lg__82393.1558127846.500.750.jpg?v=1785188291","url":"https:\/\/www.goodvibesmarina.com\/products\/sierra-18-5245-distributor-rotor-for-delco-hvs-distributors-replaces-pleasurecraft-r103011-mercury-884790-fits-mp-5-0l-5-7l-2002-2005","provider":"Good Vibes Marina","version":"1.0","type":"link"}
