Rather than sourcing individual wear parts separately, this kit bundles every component needed to fully rebuild the outboard's water pump in one purchase, including the housing itself, the impeller, wear plate, insert cup, grommet, gasket, O-rings, stainless steel mounting bolts, and washers. Replacing a worn water pump assembly restores proper cooling water flow to the engine, which is essential for preventing overheating damage to the powerhead.\u003c\/p\u003e\u003cp\u003eThe kit's mounting hardware is stainless steel for corrosion resistance in the marine environment, and the impeller carries its own O.E. Reference number for verification against the original part. As with all Sierra parts, this kit is manufactured to meet or exceed the specifications of the original equipment part it replaces, specifically the OMC 393630 water pump. Because outboard water pump housings and impellers are fit specific across different engine years and horsepower ranges, buyers should confirm the OEM number on their existing pump matches before ordering.\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 18-3382\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Water Pump Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes Housing:\u003c\/strong\u003e Yes\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 0.74 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Bolts:\u003c\/strong\u003e 6 stainless steel bolts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImpeller Part Number:\u003c\/strong\u003e 18-3051 (O.E. #395289)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Engine Type:\u003c\/strong\u003e Johnson\/Evinrude Outboard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e OMC 393630\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eDesigned for use with Johnson\/Evinrude outboard engines.
