New pump, or just new motor?

So do think that if the rest of the filter portion is in good shape then I should just get a new motor?

Usually the biggest problem is getting the whole thing apart to replace the motor and then finding the parts to put it back together again.

If you have all the seals and gaskets you need to put it all back together and you are satisfied that the pump screen assembly is in good shape then a motor only is the way to go.

Motors are paired with impellers so if you replace the motor, you must use exact braking HP to determine the replacement (HP * SF). Otherwise, the motor could be overloaded or underloaded.

Also, because the rest of the parts are 20 years old and probably need replacement as well, if it were me, I would replace the entire pump.
