Hayward Northstar Pump with Emerson Motor K63CXEPZ-476

I have a Hayward Northstar pump for my pool. The motor runs hot and trip the breaker. I tore it apart to see if it was the pump or the motor. I suppose it is the motor since the pump and impeller all look perfect. The motor spins easy enough but doesn’t sound quite right. My questions is should I rebuild this motor or replace it with a more efficient one?

Emerson 1.5 HP model 1081 – attached photo is the label. Can you give me suggestions on a replacement motor or am I just as good with a rebuild? If a more efficient motor available and worth it?
