This will be my second winter with a boat, so I'm still a bit new at all of this. I like to use my boat year round, and did last year. I'm in West Texas, so it does get cold and freeze, but not like what you guys up north experience. Last year I had an old boat with an outboard. Becuase of the age I really didn't care so much about the risk. This year I have a newer stern drive. Since I have more money in it, I'm a bit more concerned. A friend told me to keep the tarp on and place a ceramic heater by the engine on the really cold nights. Feedback?
