After waiting 2 weeks for it to show up after it disappeared into the aether between them and FedEx it finally got to me. Customer service was generally unhelpful.
I was pretty pleased with how the motor was crated up for shipping. The motor arrived with some scuffing on the motor housing from the factory as that was covered with Styrofoam when i opened it up. That doesn't bother me much long as it functions and its not bare metal to rust.
It definitely seems under powered compared to the 7.5hp US Motors unit it is replacing, so I'm not sure I buy that it is truly 7.5hp itself. That said, it does spin up and drive the air pump on the compressor as it should if slower. We'll see about longevity. If it lasts a while I would buy it again for the price. Still planning to see if I can get the older and better original motor rebuilt.
