Rather than sourcing each wear component separately, this kit bundles the impeller, upper pump housing, water pump base, and all the gaskets, seals, and hardware needed to fully rebuild the outboard's water pump section in one job. At the core of the kit is the impeller (O.E. 47-89983), which drives raw water through the cooling system, paired with the upper pump housing (O.E. 46-77822A1) and water pump base (O.E. 46-77177A1) that the impeller seats and rotates within. Rounding out the kit are drain gaskets, a lower water pump base, face plate gaskets, water pump base gaskets, a drain plug, a plate, and three O-rings, so a technician has every wear part on hand for a single teardown rather than reordering mid-job when a gasket or O-ring turns out to be missing. This makes the 18-3324 kit suited to a full water pump service rather than a single-impeller swap. The kit ships as one packaged unit and is manufactured with a country of origin of China.\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 18-3324\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaces (OEM):\u003c\/strong\u003e 46-77177A3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Mercury\/Mariner Outboard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.52 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e China\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999315861\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImpeller Part Number:\u003c\/strong\u003e 47-89983\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUpper Pump Housing Part Number:\u003c\/strong\u003e 46-77822A1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Pump Base Part Number:\u003c\/strong\u003e 46-77177A1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Includes:\u003c\/strong\u003e Impeller, upper pump housing, water pump base, drain gaskets, lower water pump base, face plate gasket, upper face plate to body gasket, water pump base gaskets, drain plug, plate, and O-rings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eThe Sierra 18-3324 Water Pump Kit is a replacement for the Mercury\/Mariner Outboard water pump assembly identified by Mercury Marine part number 46-77177A3.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e46-77177A3\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-3324 Water Pump Kit replace?\u003c\/strong\u003e It replaces Mercury Marine part number 46-77177A3, the OEM water pump housing kit for Mercury\/Mariner outboards.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a full water pump rebuild kit or just an impeller?\u003c\/strong\u003e The 18-3324 is a full rebuild kit, not a single impeller.
