Thanks for info I have a total enclosure and was concerned on the frosting up. I fish Saginaw Bay and many times we run out 10 miles.I have ridden in about 10 degree F up to 30. Through snow on frozen lakes and drifts in the open. No fogging on EMP windshield (also have EMP rear, but doubt that changes anything.) Unless there is sleet, I don't think you have to worry.
This don't sound good many times it's below zero hereFirst, I want to say that I have never been ice fishing. I live in the heat of East Texas. However, we do get cold weather here. This winter when it got below 35 my Ace would barely start. It turned out to be a spark plug. The only symptom that I had was hard to start in cold weather. I now carry a spare spark plug at all times. Not only carry a spare, but learn how to change the plug. At least to me, it was not obvious. I would not be 10 miles out on the ice without a spare spark plug.
