Hayward Super Pump replacement

[mnevar]

I have a 12 year old super pump that just quit working when I opened the pool. It just hums. I got it going for a couple of days by manually turning the impeller (the impeller was 'stuck'. Took me a bit to get it unstuck). Yesterday, it was back to humming. I checked here and found the advice for cleaning the contacts. I did, but it made no difference. I put a piece of paper between the contacts and the humming sound stays the same, so I tried replacing the capacitor today. No difference. I tried turning the impeller manually again with no luck. It turns fairly easily, but not smoothly. Not sure if it should. When I put power to the motor, I can see the impeller turn a tiny bit before giving up.

Edit. I take that part back. When I turned it manually, all I was doing was loosening the impeller from the drive shaft. The shaft still turns when putting power to the motor, but only 1/8 to 1/4 of a turn.

If I replace just the motor, are there any online places that are recommended?

I was thinking of doing a whole pump replacement because I've seen talk here of 2 speed pumps and thought that would be more energy efficient, however I don't see this mentioned in any of the catalogs. Can you recommend a replacement pump if I go that way?

Edit. After some searching, I see the Super II and TriStar are 2 speed pumps. Any advise?

Current pump is 1.5 hp, wired for 220v.

Thanks,
Mark
