It is designed for use in 4 stroke gasoline outboard engines and functions as the rotating component inside the water pump housing that drives raw water through the cooling system, protecting the powerhead from overheating. Each unit ships as a single impeller (one included per package) and is finished in black.\u003c\/p\u003e\u003cp\u003eSierra manufactures marine parts to equivalent fit, form, and function as the original equipment they reference, making the 18-3054 a straightforward like-for-like replacement when a water pump impeller needs to be swapped out during routine maintenance or a water pump rebuild. Replacing a worn or cracked impeller on schedule helps prevent engine overheating caused by reduced water flow, one of the most common causes of outboard cooling system failure.\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 18-3054\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Impeller\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Type:\u003c\/strong\u003e 4 Stroke\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Type:\u003c\/strong\u003e Gasoline\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Transom Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.03 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions:\u003c\/strong\u003e 15.24 cm L x 9.398 cm W x 5.08 cm H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e Impeller\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999315106\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGTIN:\u003c\/strong\u003e 00030999315106\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e China\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eDesigned for Mercury Marine outboard engines that use OEM water pump impeller 47-89980.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e47-89980\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-3054 fit?\u003c\/strong\u003e The Sierra 18-3054 is built as an equivalent for Mercury Marine outboard engines that use OEM water pump impeller 47-89980.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-3054 the same as Mercury Marine 47-89980?\u003c\/strong\u003e Yes, the 18-3054 is manufactured as a direct equivalent to Mercury Marine part number 47-89980 and is intended as a like-for-like replacement.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included when I order this part?\u003c\/strong\u003e One Sierra 18-3054 impeller ships per package; no additional water pump housing components, gaskets, or hardware are included.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Sierra 18-3054 impeller?\u003c\/strong\u003e It is black.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sierra 18-3054 weigh?\u003c\/strong\u003e The impeller weighs 0.03 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the package dimensions of the Sierra 18-3054?\u003c\/strong\u003e The part ships in packaging measuring 15.24 cm long by 9.398 cm wide by 5.08 cm high.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this impeller genuine Sierra or aftermarket?\u003c\/strong\u003e The 18-3054 is a genuine Sierra-branded part manufactured as an OEM-equivalent replacement, not a repackaged Mercury Marine original.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat type of engine is the Sierra 18-3054 designed for?\u003c\/strong\u003e It is designed for use in 4 stroke gasoline outboard engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere is the Sierra 18-3054 impeller made?\u003c\/strong\u003e This impeller's country of origin is China.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I know if my impeller needs replacing?\u003c\/strong\u003e Reduced raw water flow, engine overheating, or a cracked or worn impeller vane are signs that the water pump impeller, such as the Sierra 18-3054, needs to be replaced.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-3054?\u003c\/strong\u003e The UPC is 030999315106.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988137554139,"sku":"SIE-18-3054","price":19.3,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-3054_lg__52232.1558123813.500.750.jpg?v=1785188214","url":"https:\/\/www.goodvibesmarina.com\/products\/marine-water-pump-impeller-for-mercury-outboards-replaces-mercury-47-89980-47-68988-sierra-18-3054","provider":"Good Vibes Marina","version":"1.0","type":"link"}
