Hey Pat, you are going to like that pump. I just added one of those to my new motor and I'm having trouble building heat. In other words it runs too cool even after changing from a 160* stat to a 180*. This was over our wimpy Fl winter. Waiting on full summer here to see the real test. But so far I am impressed with that pump. Oh, and I also used the Stewart stat by Robertshaw, very good product. It seems like it is all woking together keeping things running super cool. But like I said the real test is yet to come. Fernando
