I wouldn't even think about taking my boat out in this shit with out a heated grage. Made it out yesterday for a one hour limit.Had to do it again to day
never even made it out of the launch and fell in off the back of the boat 
saved the day for my bro thoe he took the boat out while I finished my hearattack in the truck getting the feeling back in my hands. I need to do somthing to keep the boat from freezing to the trailer. My boat will float with the trailer froze to it. I even got the trailer air born trying to get it to bump off.This is why I fell off the back of the boat. It's hard to stand on a hunt deck with an 1" of ice on it. You definitely need a motor cover I would think the road salt spray would be hard as hell on electrical connections.my boat turns white the next day in the shop from the road spray. Looks like it was a bad day for both of us I tell everyone if you want to test the limits of hunting gear use it in -20 weather if it works you know it's tough.
