I live in south central kentucky. I would say average winter temps at night are around in the teens. I have a 1999 Evinrude 175 Ficht. I have already changed the lower unit oil. I will also add stabil to the fuel. I plan on using it at least a couple times a month to crappie fish. I keep it covered in a barn when I am not using it. Just wondering if I have to winterize it or any suggestions would be appreciated this is my first boat.
