Hi all. I need your opinions on a little problem. I was planning on winterizing my speedster next weekend but it appears mother nature is being a little premature with the cold weather and they are calling for overnight lows of -5C ( 22F). I was away all this past weekend and had very little time when I got home last night and didn't have any of the supplies needed to winterize. I charged to cooling systems of both engines with low pressure compressed air and managed to get a substantial amount of water out of both. Do you think this will be sufficient to get me to the weekend? The boat is stored in the garage (unheated).
