I have 6 month old Northstar 1-speed pump that I'm considering upgrading to a 2-speed. I've noticed prices of the Northstar 2-speed pumps to be in the $600 range, whereas replacement motors are only in the $200-$300 range.

Is it a viable option to just replace the motor when upgrading to a 2-speed pump? I'm assuming the pump itself is identical between 1 and 2-speed models? I'm hoping to not only save money, but also avoid having to redo the pump plumbing.

I'd be hooking the new motor to my Aqua Logic PS-8, which should already support the 2-speed pumps.

Thanks!
