The impeller is the wear component inside the drive's water pump that circulates raw water through the cooling system, and it is one of the parts most commonly replaced during routine water pump service or when cooling flow drops off. Each unit is sold individually as a single impeller for use in the Generation II \/ MR Alpha water pump assembly.\u003c\/p\u003e\u003cp\u003eSierra cross-references this impeller to OEM numbers from Chrysler Force, Honda, and Mercury Marine, making it a straightforward equivalent when you know your engine's original part number but want a Sierra-branded replacement. Confirm your drive's serial number against the 0D494569-and-above range before ordering, since earlier Alpha One serial ranges use different Sierra impeller part numbers.\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 18-3056\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Water Pump Impeller\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e MerCruiser Alpha One Generation II and Vazer, serial number 0D494569 and above\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e Chrysler Force 47-43026-2, Honda 19210-ZW1-003, Mercury Marine 47-43026-T2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.13 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999315120\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 1 impeller\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMerCruiser Alpha One Generation II and Vazer, serial number 0D494569 and above\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eChrysler Force 47-43026-2\u003c\/li\u003e\n\u003cli\u003eHonda 19210-ZW1-003\u003c\/li\u003e\n\u003cli\u003eMercury Marine 47-43026-T2\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-3056 impeller fit?\u003c\/strong\u003e It is built for the MerCruiser Alpha One Generation II and Vazer water pump assembly, specifically units with serial number 0D494569 and above.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill 18-3056 work on an earlier Alpha One serial number?\u003c\/strong\u003e No. The 18-3056 impeller is designated for serial number 0D494569 and above; earlier Alpha One serial ranges use different Sierra part numbers within the same water pump family.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat OEM part numbers does the Sierra 18-3056 cross-reference?\u003c\/strong\u003e It cross-references Chrysler Force 47-43026-2, Honda 19210-ZW1-003, and Mercury Marine 47-43026-T2.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does this impeller weigh?\u003c\/strong\u003e The Sierra 18-3056 impeller weighs 0.13 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many impellers come in the package?\u003c\/strong\u003e One 18-3056 impeller is included per package.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-3056 an OEM or aftermarket part?\u003c\/strong\u003e It is a Sierra-branded aftermarket replacement, cross-referenced to equivalent OEM numbers from Chrysler Force, Honda, and Mercury Marine.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-3056 impeller?\u003c\/strong\u003e The UPC for the Sierra 18-3056 impeller is 030999315120.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs 18-3056 part of a larger water pump kit?\u003c\/strong\u003e The 18-3056 impeller is a component used in the Generation II \/ MR Alpha water pump assembly on MerCruiser Alpha One Generation II and Vazer drives.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if my drive uses the 0D494569-and-above serial range?\u003c\/strong\u003e Check the serial number stamped on your MerCruiser Alpha One Generation II or Vazer drive; the 18-3056 impeller applies only to units serial number 0D494569 and above.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I use the Chrysler Force or Honda OEM number to confirm this is the right part?\u003c\/strong\u003e Yes, if your original impeller is marked Chrysler Force 47-43026-2, Honda 19210-ZW1-003, or Mercury Marine 47-43026-T2, the Sierra 18-3056 is the cross-referenced equivalent.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988137717979,"sku":"SIE-18-3056","price":21.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-3056_lg__69099.1558123933.500.750.jpg?v=1785188091","url":"https:\/\/www.goodvibesmarina.com\/products\/water-pump-impeller-for-mercury-mariner-outboards-mercruiser-alpha-one-gen-2-replaces-47-43026-2-sierra-18-3056","provider":"Good Vibes Marina","version":"1.0","type":"link"}
