Hello I am listing this question for my grandpa. Recently he bought a boat with a 1998 25HP electric start Evinrude Outboard. The model# is E25ELEUB Serial is G04230422. When he goes to start the motor in the morning when it is cold it will not start, when he pushes the key in for choke, there is no noise back at the motor indicating the choke opening. When he goes to start it in the after noon when the temperature outside warms up it will start right up even before the flywheel makes a complete rotation all hit has to do is turn the key for a split second so it starts good just not in cold weather. Any help would be much appreciated.
