It is built around a full set of wear components so the pump can be restored to proper cooling performance in a single service, rather than sourcing individual pieces separately.\u003c\/p\u003e\u003cp\u003eThe kit contains a Sierra 18-3083 impeller along with the housing seal, gasket, impeller key, and O-ring needed to complete the job, giving the installer everything required to replace the parts that typically fail or wear out in a water pump service. Reduced water flow, overheating, or a worn impeller are the usual signs this kit is needed. Because the impeller and its related seals are the parts most prone to wear from dry-running, debris, or age-related hardening, replacing them as a set helps avoid a repeat failure shortly after service.\u003c\/p\u003e\u003cp\u003eThis kit is designed for use on Johnson\/Evinrude outboard engines and directly replaces OEM part number 384956, so it drops in as a factory-equivalent service kit rather than a modified or universal substitute. Sierra states that each of its parts meets or exceeds the original equipment part it replaces. Because fit is specific to the engine and pump housing in use, confirm the part number against your outboard 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 18-3211\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Water Pump Impeller Repair Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing Included:\u003c\/strong\u003e Without Housing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaces (OEM):\u003c\/strong\u003e 384956\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterchangeable With:\u003c\/strong\u003e GLM 12105, Mallory 9-48202\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Contents:\u003c\/strong\u003e Impeller (18-3083), Impeller Housing Seal (18-2536), Impeller Gasket (18-2557), Impeller with Key (18-3059), Impeller Key (18-3138), Impeller Key (18-3299), O-Ring (18-7158), Impeller Plate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Engine Application:\u003c\/strong\u003e Johnson\/Evinrude outboard motors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.69 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e Limited warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits Johnson\/Evinrude outboard motors that use the water pump serviced by OEM part number 384956.
