Something I learned the hard way… if it is cold enough, do not freak out when you first fire the motor up, and it doesn’t pee. I was on pool 4, ten minutes later, so worried almost pulled boat back on the trailer after driving almost six hours through the night. Well below freezing temps, and I had never had a boat out in those cold temps before.
A fellow fisherman at the dock pointed out to just let it warm up… any newer motor has a thermostat, and it will not pee until it warms up. My buddy was already heading to get the truck. Saved the trip.
