Rather than a single impeller, this kit supplies the full set of components needed to rebuild the pump assembly in one job, including the housing, impeller cup and plate assembly, O-ring, gaskets, grommet, impeller key, and mounting hardware. Sierra builds the kit to meet or exceed original equipment quality, so the rebuilt pump delivers the cooling flow the outboard was designed around.\u003c\/p\u003e\u003cp\u003eBecause it is packaged as a kit rather than a standalone impeller, the 18-3391 is suited to a full water pump service rather than a quick impeller-only swap, helping ensure worn housing and seal components are replaced at the same time as the impeller. It is built as a direct equivalent to Evinrude\/Johnson OEM part number 395072, so it installs in place of the original pump kit without modification.\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 18-3391\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Water Pump Kit with Housing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Rubber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit Type:\u003c\/strong\u003e Universal Fit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.08 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999621597\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Contents:\u003c\/strong\u003e Housing, 18-3346 Cup and Plate Assembly (O.E. 435027), 18-2769 O-Ring (O.E. 332000)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaces (OEM):\u003c\/strong\u003e 395072\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eBuilt for Evinrude and Johnson outboard engines that use the OEM 395072 water pump kit; fit type is universal within that application.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e395072\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-3391 water pump kit include?\u003c\/strong\u003e The kit includes the water pump housing along with a cup and plate assembly (18-3346, O.E. 435027), an O-ring (18-2769, O.E. 332000), and the other gaskets and hardware needed to rebuild the pump.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-3391 kit include the housing or just internal parts?\u003c\/strong\u003e Yes, the 18-3391 is a full kit that includes the water pump housing itself, not just the internal rebuild components.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs Sierra 18-3391 the same as OEM part 395072?\u003c\/strong\u003e Yes, the 18-3391 is built as a direct equivalent to Evinrude\/Johnson OEM part number 395072 and installs in its place.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat outboard brands is this water pump kit designed for?\u003c\/strong\u003e This kit is designed for Evinrude and Johnson outboard engines that use the 395072 water pump kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Sierra 18-3391 water pump kit?\u003c\/strong\u003e The kit is white.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the water pump kit made from?\u003c\/strong\u003e The pump components in the 18-3391 kit are made of rubber.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 18-3391 water pump kit weigh?\u003c\/strong\u003e The Sierra 18-3391 weighs 1.08 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a universal-fit kit or vehicle-specific?\u003c\/strong\u003e Sierra lists the 18-3391 as a universal fit kit for its applicable Evinrude\/Johnson outboards.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-3391 kit come with a new O-ring and gaskets?\u003c\/strong\u003e Yes, an 18-2769 O-ring (O.E. 332000) is included along with the other gaskets and hardware in the kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-3391 water pump kit?\u003c\/strong\u003e The UPC for the Sierra 18-3391 water pump kit is 030999621597.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 18-3391 genuine Sierra or aftermarket?\u003c\/strong\u003e The 18-3391 is a genuine Sierra-branded water pump kit, built to meet or exceed original equipment quality as a replacement for OEM part 395072.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988147024091,"sku":"SIE-18-3391","price":43.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/18-3391__74308.1739458797.500.750.jpg?v=1785188114","url":"https:\/\/www.goodvibesmarina.com\/products\/water-pump-kit-with-housing-for-evinrude-johnson-omc-outboards-replaces-395072-sierra-18-3391","provider":"Good Vibes Marina","version":"1.0","type":"link"}
