The kit is built around a housing assembly and includes a stainless steel bolt (qty. 2, part 319126) along with a dedicated impeller (Sierra 18-3050, O.E. #386084), giving installers everything needed to replace a worn or failed water pump in one package rather than sourcing individual components separately.\u003c\/p\u003e\u003cp\u003eStainless steel hardware is used for corrosion resistance in the marine environment, and the kit is engineered to meet or exceed the quality of the original equipment part it replaces. This makes the 18-3327 a direct, drop-in solution for outboards originally fitted with any of the OEM water pump components it cross-references, helping restore consistent engine cooling and prevent overheating caused by a degraded pump housing or impeller.\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 18-3327\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Water Pump Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing Included:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImpeller Included:\u003c\/strong\u003e Sierra 18-3050 (O.E. #386084)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Included:\u003c\/strong\u003e Stainless Steel Bolt, part 319126, quantity 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.42 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999875433\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 394711, 386697, 391698, 389112, 387610\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits applications originally equipped with a water pump using OEM part numbers 394711, 386697, 391698, 389112, or 387610.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e394711\u003c\/li\u003e\n\u003cli\u003e386697\u003c\/li\u003e\n\u003cli\u003e391698\u003c\/li\u003e\n\u003cli\u003e389112\u003c\/li\u003e\n\u003cli\u003e387610\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-3327 Water Pump Kit include?\u003c\/strong\u003e The kit includes a water pump housing, a Sierra 18-3050 impeller (O.E. #386084), and a stainless steel bolt (part 319126, quantity 2), giving you the complete set of components to rebuild the water pump in one package.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich OEM part numbers does the 18-3327 replace?\u003c\/strong\u003e Sierra 18-3327 replaces OEM numbers 394711, 386697, 391698, 389112, and 387610.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the impeller included in this kit, or sold separately?\u003c\/strong\u003e Yes, the impeller is included as part of the 18-3327 kit;
