Mfr # 118-3043. Evinrude, Johnson And Gale Outboard Motors Impeller Sierra Marine Engine Parts 183043 is positioned on a shaft and has a hub with attached vanes The flexible vanes are rotated on an eccentric within a stainlesssteel liner in the pump housing by the hub While the boat's engine is operating, an impeller pumps cold water into it to keep it cool The water pump in marine engines has an impeller Because there is no wall between the vanes, outboard impellers are slightly weaker than closed or semiclosed impellers The blade stresses are substantially lower The fluid enters the impeller's eye, where vanes contribute energy and direct it to the nozzle discharge The most liquid does not flow back due to a small space between the vanes and the pump volute or backplate Key Features To maintain efficiency over time, modify the clearance to compensate for wear on the bowl and edge of the vane Not more difficult to inspect for damage and maintain than closed impellers because the interior elements are visible They are more readily able to adjust the flow properties Impellers with open blades are typically faster and easier to maintain Specification SKU 183043 UPC 030999315052 Weight 035 LBS Engine Parts 183043 Impeller fitting JohnsonEvinrude Outboard applications 85235hp from 197378 This product replaces 473043, GLM89680, 9289680, AP008, 30999315052, 945203
