I recently purchased my first boat and it has a Yamaha 40/30 outboard Jet. I have found plenty of information about how to winterize an outboard, but I am unclear on what I need to be doing if I use it during winter. If I take it out in weather below freezing, what do I need to do at the end of the day? A special maintenance that I need to do different than what I do in summer? Last thing I need is to ruin my first boat motor.
