If there was a problem with any brand of 4 stroke outboards freezing we would have heard about it before now. I have personally seen 2 outboard blocks cracked from freezing. One was a 125hp Force and a 70hp Johnson. Both froze and cracked behind the exhaust cover plate. Seen lots of lower units freeze.
The world will not be destroyed by those who do evil, but by those who watch them without doing anything. Remember what He has done and remember that He is not done yet!-- GOD IS GOOD
