Hi Tom - If it were me I would go with the B2982T dual speed replacement motor which comes with a digital timer, this motor can be found for $335 you would also need a 5250-106 seal which is about $15 this is a 1 HP full rate motor which would be identical to your 1.5 HP up rate motor. The B2982T has a digital timer right on top of the motor for easy programming. There typically is really no need to replace the pump housing and replacing the motor would be fine.
