Remove impeller on hot tub pump

[Kaysue555]

The seal on my pump has failed and I am having trouble removing the impeller in the pump. It appears that turning the impeller clockwise, while holding the motor shaft with a screwdriver in the end slot, is the procedure. Mine will not budge, at least not before the screwdriver slips. I hesitate to use a lot of force until I am sure I am on the right course. Am I right as to procedure? Any tips on loosening the impeller? Any tips on holding the shaft? Pump is an Acura MagnaFlo.

Lots of impellers are pressed on. If you can see a key or not see any threads, assume it's pressed.

The last time I did one of these on mine, I ended up replacing the impeller. There was no way I was able to remove it without destroying it.

I have the same pump, and mine is NOT pressed on.

The shaft and brass insert in the impeller corrode a bit over the years. When I install new impellers, I grease the threads.
