This Pump is a Perfect Replacement for a Watkins 0982601-03 2.5HP 11.0/3.5 Amp (2) Speed 56 Frame Complete Pump.
It is about 7 1/4"" across the face of the pump, it measures about 7 3/8" from the bottom to the top of the pressure side of the volute, it also measures 15" from the back to front edge. The Suction and Pressure side thread fittings are called 2" x 2" but measure 3" from the edge of the thread to the edge of the thread.
Note: There are other companies offering other brands that are not exact fit for your tub.. This pump is an exact fit..
NOTE: This Pump looks a lot like an Aqua-Flo and a CMP Pump and they will interchange if you replace the entire pump!
