It is the wear component inside the lower unit water pump that circulates raw water through the engine block to keep it cool, and it is one of the most common maintenance replacement parts on an outboard.\u003c\/p\u003e\u003cp\u003eEach package includes one impeller. The 18-3042 is built with a high speed steel blade construction and a round blade shape. Sierra states that each of its parts meets or exceeds the original equipment part it replaces, making this impeller a direct functional replacement for the OEM Yamaha part it is designed around.\u003c\/p\u003e\u003cp\u003eThis impeller is intended to be installed as part of a complete water pump service. Sierra recommends pairing the 18-3042 with Sierra's 18-3451 Water Pump Kit or 18-3409 Water Pump Kit with Housing when performing a full pump rebuild, since impellers are typically replaced along with the surrounding pump housing components and gaskets for a proper seal and consistent water flow.\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 18-3042\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Category:\u003c\/strong\u003e Yamaha Outboard Water Pumps \u0026amp; Impellers 2 Stroke\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlade Material:\u003c\/strong\u003e High Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlade Shape:\u003c\/strong\u003e Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Multicoloured\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e Impeller\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1 impeller per package\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.08 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282256852\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eDesigned for use in Yamaha outboard engines.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e67F-44352-00-00\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sierra 18-3042 impeller used for?\u003c\/strong\u003e It is a water pump impeller designed for use in Yamaha outboard engines, circulating raw water through the engine to keep it cool.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-3042 impeller replace a Yamaha OEM part?\u003c\/strong\u003e Yes, the Sierra 18-3042 directly replaces Yamaha OEM part number 67F-44352-00-00.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many impellers come in a package?\u003c\/strong\u003e The Sierra 18-3042 package includes one impeller.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the impeller blade made of?\u003c\/strong\u003e The 18-3042 impeller has a high speed steel blade construction with a round blade shape.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-3042 impeller weigh?\u003c\/strong\u003e It weighs 0.08 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eShould this impeller be installed alone or with other parts?\u003c\/strong\u003e Sierra recommends installing the 18-3042 as part of a full water pump service, using it with Sierra's 18-3451 Water Pump Kit or 18-3409 Water Pump Kit with Housing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-3042 a genuine OEM part or aftermarket?\u003c\/strong\u003e It is a Sierra aftermarket replacement impeller, and Sierra states it meets or exceeds the original equipment part it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat engines is the 18-3042 impeller compatible with?\u003c\/strong\u003e The 18-3042 is designed for use in Yamaha outboard engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-3042 interchangeable with any other brand parts?\u003c\/strong\u003e The Sierra 18-3042 is interchangeable with Mallory part number 9-45612.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat UPC is associated with the 18-3042 impeller?\u003c\/strong\u003e The Sierra 18-3042 impeller carries UPC 808282256852.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need a full water pump kit to replace just the impeller?\u003c\/strong\u003e Not necessarily, but Sierra pairs the 18-3042 impeller with its 18-3451 or 18-3409 water pump kits for a complete pump rebuild rather than an impeller-only swap.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988136931547,"sku":"SIE-18-3042","price":29.89,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-3042_lg__62772.1558123104.500.750.jpg?v=1785188075","url":"https:\/\/www.goodvibesmarina.com\/products\/water-pump-impeller-for-yamaha-outboards-replaces-yamaha-67f-44352-00-00-sierra-18-3042","provider":"Good Vibes Marina","version":"1.0","type":"link"}
