I Planned on winterizing this weekend, but the temperature dipped down to 28 last night. I have a 1970 115 hp mercury Ouboard. How much trouble am I in. I hve heard that the outboards will drain when in the down tilt position. Will this get me by until this weekend. Also, If I wanted to use the boat for hunting or late season fishing, how do I keep it from freezing in between trips? Thanks
