This part is sold as a single impeller per package and is built to meet or exceed the specifications of the original equipment part it replaces. The impeller is white in color and is a precision-fit component, so buyers should confirm part numbers against their engine before ordering to ensure proper fit.\u003c\/p\u003e\u003cp\u003eThe water pump impeller is a critical wear item in an outboard's cooling system, drawing raw water through the pump housing to cool the engine. Because impeller blades flex and wear with use, periodic replacement helps maintain proper cooling flow and can help prevent overheating. The Sierra 18-3067 is listed under Sierra's Yamaha Outboard Water Pumps and Impellers, 2 Stroke category, and replaces Mercury Marine part number 47-84797M.\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 18-3067\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Impeller\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 0.04 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 030999315199\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1 impeller per package\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Mercury\/Mariner and Yamaha outboard engines\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Yamaha Outboard Water Pumps and Impellers, 2 Stroke\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaces (OEM):\u003c\/strong\u003e 47-84797M\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eDesigned for use with Mercury\/Mariner and Yamaha outboard engines.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e47-84797M\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the Sierra 18-3067 impeller fit?\u003c\/strong\u003e The Sierra 18-3067 is designed for use with Mercury\/Mariner and Yamaha outboard engines.
