Yeah, when I received the cox reel, I had to look up the motor information myself to see what was required to run the air motor. I modified the muffler on my air motor due to it being in the upright position. I learned the hard way. If you wash anything around it, or it rains, it will run down the muffler into the fins of the motor. I washed it and put it away last year, and before blow out season this year, the motor was froze tight. Had to disassemble and clean out really well. I put a 90 degree elbow on the base of the muffler, so nothing can run inside the motor when not in use. I have since purchased only electric driven reels now. Air motor has been kind of a pain.
