Water Pump Impeller 12 Blade 145410-46090 831182 4568-0001 for Yanmar Volvo Penta Jabsco Johnson 57 mm — Australia Local Warehouse
Product Overview
Water pump impeller for Yanmar, Volvo Penta, Jabsco, Johnson and Oberdorfer pumps, a 12 blade key drive neoprene impeller at 57 mm diameter, 31.5 mm width and 15.8 mm shaft diameter with a brass insert. It replaces Yanmar 145410-46090 and 145410-46050, Volvo 831182, 835182, 875573, 875575 and 21951350, Jabsco 4568-0001, 4568-0003 and 4568-0001P, and Johnson 09-801B. Dispatched from our Australia local warehouse.
The dimensions are what matter here rather than the number on the box. Several makers used this same 57 mm by 31.5 mm body with a 15.8 mm hub, and the cross reference below is long for that reason. If the old impeller is worn enough that the number has gone, measure it: twelve vanes, brass insert, and a keyed bore rather than a splined one.
On a raw water cooled diesel the impeller is also the cheapest early warning you get. Vanes that have taken a set will still pump at idle and stop pumping at cruising rpm, which shows up as a temperature gauge that climbs slowly over twenty minutes rather than an alarm that goes off.
