Water Pump Impeller 145410-46090 4568-0001 831182 for Volvo Yanmar Jabsco 57 mm 12 Blade
Water Pump Impeller 145410-46090 4568-0001 831182 for Volvo Yanmar Jabsco 57 mm 12 Blade
Product Overview
Water pump impeller for Volvo Penta AQ131, AQ140 to AQ170 and MD21 and MD42 engines, Yanmar 3QM diesels, Jabsco and ITT 4568 pumps, Johnson F5 pumps, Oberdorfer 301, 302 and 303M pumps and Gray Marine six cylinder engines, 57 mm diameter, 31.5 mm wide, 15.8 mm key drive shaft, 12 blades, replacing 831182, 4568-0001 and 09-801B.
This is the 12 blade 57 mm impeller that fits the key drive pumps on both the older Volvo Penta petrol engines and the Yanmar and Gray Marine diesels. Twelve blades at this diameter move enough water for a compact pump mounted low on the block.
Key drive, not spline. One key sits in the shaft and drives the hub, so check the key and the keyway before ordering. A rounded keyway or a missing key will let the impeller slip on a new shaft, and the pump will lose flow long before the blades wear out.
