The kit includes the water pump base along with the components needed to replace a worn or failing pump assembly, helping prevent overheating caused by reduced water flow through the cooling system. It is built as a direct equivalent to Mercury Marine 46-42579A4, so it installs in place of that OEM part without modification. Marine mechanics and boat owners performing routine maintenance or addressing an overheating outboard can use this kit to replace the water pump housing and base together rather than sourcing separate components. Because water pump wear is a common maintenance item on outboard motors, keeping a cross-referenced replacement kit on hand simplifies servicing and reduces downtime. This kit is cataloged under EMP part number 46-13171 for easy reordering.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e EMP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 46-13171\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Water Pump Kit with Base\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Mercury Outboard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 840080496603\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.891 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eMercury Outboard\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eMercury Marine 46-42579A4\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the EMP 46-13171 water pump kit include?\u003c\/strong\u003e The EMP 46-13171 kit is a water pump kit with base, providing the pump housing and base needed to replace a Mercury outboard water pump assembly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs EMP 46-13171 the same as Mercury Marine 46-42579A4?\u003c\/strong\u003e Yes, EMP 46-13171 is a direct replacement for Mercury Marine 46-42579A4 and installs in its place.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat outboard motors does this water pump kit fit?\u003c\/strong\u003e This water pump kit with base, EMP part number 46-13171, is designed to fit Mercury outboard motors.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the EMP 46-13171 water pump kit weigh?\u003c\/strong\u003e The EMP 46-13171 water pump kit with base weighs 0.891 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this kit come with a base plate?\u003c\/strong\u003e Yes, the EMP 46-13171 kit is a water pump kit with base, so the base plate is included along with the pump housing components.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs EMP 46-13171 an OEM Mercury Marine part or aftermarket?\u003c\/strong\u003e EMP 46-13171 is an aftermarket water pump kit manufactured to replace Mercury Marine 46-42579A4.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat UPC is associated with the EMP 46-13171 water pump kit?\u003c\/strong\u003e The EMP 46-13171 water pump kit with base carries UPC 840080496603.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy would I need to replace my outboard's water pump kit?\u003c\/strong\u003e A worn water pump reduces cooling water flow to an outboard motor, and replacing it with a kit like the EMP 46-13171 helps restore proper engine cooling.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I use EMP 46-13171 to replace just the impeller, or is it a full pump kit?\u003c\/strong\u003e EMP 46-13171 is a full water pump kit with base rather than an impeller-only part, covering the pump housing and base assembly.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat category of part is EMP 46-13171 listed under?\u003c\/strong\u003e EMP 46-13171 is categorized as a Mercury outboard water pump and impeller component, specifically a water pump kit with base.\u003c\/p\u003e","brand":"EMP","offers":[{"title":"Default Title","offer_id":48991289573595,"sku":"EMP-46-13171","price":49.6,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/EMP-46-13171-Merucry-Mariner-Water-pump-kit-with-base__18444.1722512570.500.750.jpg?v=1785329113","url":"https:\/\/www.goodvibesmarina.com\/products\/water-pump-kit-with-base-for-mercury-outboards-replaces-oem-46-42579a4-mpn-46-13171","provider":"Good Vibes Marina","version":"1.0","type":"link"}
