I either use the original can or put the corn in a plastic tub such as Tupperware or similar, top off with water and freeze. When going fishing, simply thaw, drain some liquid off and use. Then when done, repeat the process.
I have used a Minn-Kota Autopilot for 15 years on a 17.5' Smokercraft. A couple of years ago I upgraded to the wireless remote and love it. I can control the motor from anywhere in the boat. If I had to replace the motor I would get the same setup.
