Rather than sourcing an impeller, gasket, and O-ring separately, this kit bundles everything into one part number so the water pump housing can be rebuilt in a single service. The kit includes a replacement impeller (18-3058), a water pump housing gasket (18-2916), and an O-ring (18-2541), each matched to the OEM specifications of the components they replace. Using a matched kit like this helps ensure the water pump housing reseals properly, which is critical to maintaining cooling water flow through the engine. This kit is built by Sierra, a long-standing manufacturer of marine engine parts, and is intended as a direct equivalent for OEM part number 984461. Boat owners servicing an OMC water pump can use this kit at the same time as a full water pump service to replace all of the wear items in one step, rather than reinstalling a used gasket or O-ring alongside a new impeller.\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 18-3212-1\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\u003eKit Contents:\u003c\/strong\u003e Impeller (18-3058), Water Pump Housing Gasket (18-2916, O.E.M. 911702), O-Ring (18-2541, O.E.M. 911704)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 984461\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.46 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282243845\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eDesigned for OMC water pump housings that use impeller and gasket assembly 984461\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e984461\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-3212-1 impeller repair kit include?\u003c\/strong\u003e The kit contains three components for a water pump housing rebuild: an impeller (part 18-3058), a water pump housing gasket (part 18-2916, O.E.M. 911702), and an O-ring (part 18-2541, O.E.M. 911704).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs 18-3212-1 a direct replacement for OEM part 984461?\u003c\/strong\u003e Yes, Sierra part 18-3212-1 replaces OEM part number 984461.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does this impeller kit weigh?\u003c\/strong\u003e The Sierra 18-3212-1 impeller repair kit weighs 0.46 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need any other parts to rebuild my water pump with this kit?\u003c\/strong\u003e The 18-3212-1 kit supplies the impeller, housing gasket, and O-ring needed for the water pump housing itself; it does not include the water pump housing or additional hardware beyond these three parts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the impeller in kit 18-3212-1 sold separately?\u003c\/strong\u003e Yes, the impeller included in this kit is Sierra part number 18-3058, which is one of the three components bundled into the 18-3212-1 repair kit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat gasket comes with the 18-3212-1 kit?\u003c\/strong\u003e A water pump housing gasket, Sierra part 18-2916 with O.E.M.
