How to Match This Part
This is a flexible rubber raw water pump impeller. It sits inside the pump housing behind the cover plate and is driven by a splined shaft. It replaces the primary original part number Jabsco 17018-0001, and is also supplied against JMP 7446-01 and Caterpillar 3N5895.
Match this part by checking your engine in this order:
1. Original impeller part number (stamped on the old impeller or listed in the pump section of your parts catalog)
2. Width (this listing is 76 mm / 3 in. wide, not the 50 mm 920-0001 or 68 mm 31130-0061)
3. Drive type (this listing is a 12-spline hub, not a key drive)
4. Pump model (cast or labelled on the pump body)
Identify it physically before ordering. This impeller has eight vanes moulded in black neoprene around a machined brass 12-spline insert (Jabsco Profile M). JMP 7446-01 is 65 mm diameter, 76 mm width and 16 mm (5/8 in.) bore. It is not interchangeable with 8-blade 50 mm spline 920-0001 or 10-blade 68 mm spline 31130-0061.
