I don't know what you did or didn't do with that Minnkota, but your results are so strikingly at variance with than mine that I feel I have to comment. Using an Minnkota Endura 50 with a 12 VDC battery pack weighing 80 lbs,myself at 190lb in a 16 ft 250 lb flat bottomed skiff, I routinely do 4 mph. My Endura 30 pushes it to 3.6 mph.
