It is designed to restore cooling system performance on outboards that use a matching water pump housing already in service, giving boat owners an economical way to renew wear components rather than replace the entire pump assembly. This kit is the same build as the Sierra 18-3408 kit, but 18-3429 omits the housing for applications where the original housing is still serviceable.\u003c\/p\u003e\u003cp\u003eThe kit bundles the wear items that fail most often in a water pump: bolts, a gasket, wear plates, an impeller, and an insert cup, so the full wear path of the pump can be renewed in one job. The color of the kit components is white. Each Sierra part is built to meet or exceed the specification of the original equipment part it replaces, and the kit cross-references directly to Yamaha OEM water pump repair kit part numbers, making it a straightforward drop-in replacement for outboards that call for those Yamaha kits.\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 18-3429\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Water Pump Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing Included:\u003c\/strong\u003e Without Housing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.52 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions (L x W x H):\u003c\/strong\u003e 5 x 4.5 x 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999975768\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Cross Reference:\u003c\/strong\u003e 6H4-W0078-00-00, 6H4-W0078-A0-00\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Contents:\u003c\/strong\u003e Bolt 18-0256 (qty 2), Bolt 18-0258 (qty 2), Gasket 18-0292, Wear Plate 18-0294, Impeller 18-3068, Insert Cup 18-3435, Wear Plate 18-3436\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits Yamaha outboard water pumps that use the 6H4-W0078-00-00 \/ 6H4-W0078-A0-00 repair kit.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e6H4-W0078-00-00\u003c\/li\u003e\n\u003cli\u003e6H4-W0078-A0-00\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Sierra 18-3429 water pump kit include?\u003c\/strong\u003e The kit contains 2 bolts (18-0256), 2 more bolts (18-0258), a gasket (18-0292), two wear plates (18-0294 and 18-3436), an impeller (18-3068), and an insert cup (18-3435), covering the wear parts of a Yamaha outboard water pump rebuild.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-3429 kit come with a pump housing?\u003c\/strong\u003e No, the Sierra 18-3429 kit is supplied without the pump housing.
