A new guy here, a new pool owner. In ground pool. The impeller broke on my hayward super II. The pump is old, the model and serial number have faded into the past. I ordered a new impeller per the part numbers on the old impeller. The part number from the old impeller is for a 1 HP unit, but the motor is 3/4 horse. But i figured the 1 HP impeller worked before it will work again. I put it on, now the motor is running hot and the thermo will shut it off. What gives? Any advice would be great!

Which impeller number did you buy?
Can you read the service factor on the motor?
Is the motor or pump making any noise when it's running?

The impeller part # SP3010-c
Service factor? I don't understand. I looked, i did not see anything.
The motor sounds the same, the pump does not sound the same.

The total hp is rated hp x service factor (s.f on motor).
The SP3005C impeller takes a total hp of 0.75.
The SP3007C impeller takes a total hp of 1.10.
The SP3010C impeller takes a total hp of 1.50.
The SP3005C impeller takes a total hp of 0.75.
The SP3007C impeller takes a total hp of 1.10.
The SP3010C impeller takes a total hp of 1.50.
I understand. I guess what is puzzling me is why did the 3/4 hp motor work fine with the 1 hp impeller until i put on a new one that was the exact same thing?
What is the total hp of the motor?
What was the part number on the old impeller.
Does the shaft turn freely by hand?
Is the voltage correct?

The total HP is 3/4 horse for the motor.
The part number for the old impeller is sp-3010-c.
I took it back apart tonight to look for signs of wear and tear or if something was rubbing. Nothing!
Yes It did check that.

I recommend the SP3005C impeller.
I don't know why the old impeller worked with that motor.

That sounds about right. It is strange, but something is dragging on the motor and making it heat up, the impeller is the only thing it could be.
If the old impeller was clogged, it would use less power because it would pump less gpm.
Good point. It had hair of coarse, a rubber o-ring and a small nail. Weird huh? I died right after I put in the D.E. through the strainer.
If the impeller was clogged enough such that the flow was reduced by about 20 to 30 percent of what it would be with a clean impeller, that would reduce the load on the motor enough to make it work.
That Super II pump is a full rated pump and I've found pictures of them on the net that have a 3/4 hp 1.65 SF motor on them. With that the SFHP would be 1.24 hp so it'd still be less than the rating of the impeller.
Take the old and new impeller and measure the outside diameter. Let us know if they're different.
If you can't send that one back you could have a local machine shop trim the outer diameter down a little. The Sp3010C is 4-3/4" diameter and the SP3007C is 4-11/16" OD, So if you had 1/16" to 1/8" trimmed off of it, it should run fine.

Clever:
I assume you already corrected your issues with your pool pump. I had issues like this with my pump that was removed and taken for service. Turns out the motor wiring was backward (hot and neutral) and the ground had issues as well. Make sure the electrical connections are correct. Make sure the ground is proper.
