Purchased a 3/4 HP 2 speed motor today for my pump. It's re-manufactured so the price was right. Looking forward to getting it installed. I'll replace the seal and add a hi/low switch to the cover when it comes in and use my same timer. I'm planning on running it on low. I'll update and let you know how it works out. I'll keep my old motor as a backup. The pay back should be about 2 years (20 months).
