It is designed to restore proper cooling system function on outboards using this pump configuration, replacing OEM part number 382468.\u003c\/p\u003e\u003cp\u003eThe kit includes an impeller (Sierra part 18-3002, O.E. 375638) along with four stainless steel bolts (part 319126) needed to complete the water pump rebuild. Because the housing is not included, this kit is intended for owners who already have a serviceable housing and only need the wear components -- primarily the impeller, which is the part most commonly worn out in a marine water pump -- replaced. Stainless steel hardware resists corrosion in the marine environment, helping ensure a secure, long-lasting reassembly.\u003c\/p\u003e\u003cp\u003eThis kit is intended for Johnson\/Evinrude outboard motors using the water pump assembly that takes OEM part 382468. Always confirm your existing housing and pump configuration are compatible with this kit before ordering, since the housing itself is sold separately.\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 18-3377\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Type:\u003c\/strong\u003e Without Housing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImpeller Included:\u003c\/strong\u003e Yes, Sierra part 18-3002 (O.E. 375638)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Material:\u003c\/strong\u003e Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Quantity:\u003c\/strong\u003e 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Part Number:\u003c\/strong\u003e 319126\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.19 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Johnson\/Evinrude Outboard Motor\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eJohnson\/Evinrude Outboard Motor\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e382468\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-3377 water pump kit include?\u003c\/strong\u003e It includes an impeller (Sierra part 18-3002, O.E. 375638) and four stainless steel bolts (part 319126) needed to rebuild the water pump.
