I remember one time I was bringing my son duck hunting (an hour away from the house) and I just had a bad feeling all that morning for some reason. Launched the boat and the engine wouldn't crank. Loaded the boat back on the trailer and went home. Felt bad that we didn't get to hunt but I have learned to trust my instincts on things like that. Turned out that the stater was starting to go bad. If I would have waited till it warmed up a bit it probably would have started.
