If I'm trailering it I will turn the key on and give it 1 crank to make sure the battery isn't dead at the ramp, that happened once and hopefully never again as I held everyone up to get the trailer. If that happened again I would have pulled it out of the way by hand to keep the ramp open. Rookie move. All it was is a loose battery nut. Simple stuff usually. Missed a day of fishing for a loose nut. If I'm heading out of town I will put a trickle charge on the batteries overnight but once it starts in the spring that's it. It's called confidence in my equipment. Now watch, I've kyboshed myself. There's nothing wrong with what you are doing until you are confident she'll start every time. I never start any marine engines dry out of water, never, turn it over once yes, but never fire her dry.
