It is built to replace the original equipment water pump components that wear out over time, restoring proper cooling water flow to the powerhead. The kit includes the core wear items needed for a water pump rebuild: an impeller, a grommet, and stainless steel mounting bolts, so the parts that typically fail or degrade in service are replaced together rather than piecemeal.\u003c\/p\u003e\u003cp\u003eThe impeller (Sierra 18-3053-1, O.E. 396725) is the pump's flexible drive component that pushes cooling water through the engine, and the grommet (Sierra 18-2703, O.E. 314008) seals the pump housing interface. Two stainless steel bolts (O.E. 319126) are included for corrosion-resistant reassembly. This kit is designed to meet or exceed the quality of the original equipment part it replaces, making it a straightforward drop-in solution for water pump service on compatible Johnson\/Evinrude outboard motors.\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 18-3387\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Water Pump Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing Included:\u003c\/strong\u003e No (without housing)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImpeller Part Number:\u003c\/strong\u003e 18-3053-1 (O.E. 396725)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrommet Part Number:\u003c\/strong\u003e 18-2703 (O.E. 314008)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Material:\u003c\/strong\u003e Stainless Steel (O.E. 319126, Qty 2)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999621559\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.98 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eJohnson\/Evinrude outboard motors\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e432956\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-3387 Water Pump Kit include?\u003c\/strong\u003e The kit includes an impeller (Sierra 18-3053-1, O.E. 396725), a grommet (Sierra 18-2703, O.E. 314008), and two stainless steel mounting bolts (O.E. 319126).
