Sorry, I just saw this post and would like to add my experience to save someone else some time. I have an AquaPro 75 pound and an AquaPro 200 pound feeder. I have had no problems with the 75 pound unit. The 200 pound unit kept blowing the 7.5 amp fuse, but a quick call to Aquapro and a 10 amp fuse solved the issue.
The other issue was the feed quit spitting out. Looking at the bottom of the feeder, I noticed two chewed up wires sticking out the drain hole. Not sure what they call it, but the bottom motor, for the vertical spinning plate, had it's wires disconnected and pulled loose. A Racoon had reached in the bottom drain hole and assisted me on reducing my feed costs.
After pulling off the bottom cover, I bought a couple of 16 ga. male connectors, crimped them on what are still long wires, then duct taped the wires up to the bottom of the feed pan, the same as the wires for the top motor are, already. 3 months later, and still no further issues. I've even watched the 'Coons reaching in, with no adverse affects.
I am thinking about putting a piece of sheet metal under the feeder, at an angle into the water to get fewer pellets on the shore for the Coons to eat. It's very little, but enough to entice the Coons and stray cats.
