For sale is a 3 HP single phase Marathon motor. Look at the nameplate for details. Can be rewired for 120V, not that I think that's a smart idea. Lacks cover on the box for incoming wires. You can make one yourself if you feel like you need it.
I tested this motor, it starts up instantly and runs rather quetly.
Shipping on this motor will be $45, it weighs 90 lbs.
