I have a 2 hp Sta-Rite Dura-Glas II pump (model P4RA6G-188L). I'd like to lower the output on the pump and am considering replacing the 2 hp motor with a 1 hp motor, the A.O. Smith USQ1102 for example. My thought is to replace the seal and o-rings but reuse the impeller. Are there potential problems with doing something like this, such as overloading the new motor?
