One motor moves the boat along but in a circle, I have no idea how fast. I use this setup to get a lower speed for docking as the I/O minimum speed is 5 mph. Batteries are too poor to get meaningfull specs for range. The boat is a cabin cruiser so is heavy, maybe 5000 ibs fully loaded. I think a large torqueedo would be needed to get the speed you are after, twin 4.0r's would be a nice setup if you have the cash. Twin 101 thrust trolling motors might work but no reserve power and not as efficient. Just guessing here.
