I have a 1990 25 HP Merc with electric start and console controls that is driving me crazy... This guy will start and run great. Turn it off and come back an hour or two later and it cranks all day long and won't start. Come back tomorrow and it fires right up. ARGH! Checked the plugs when this was happening an no spark to either one.
So I checked the resistance on the stator and it was lower than what the manual said it should be. Replaced the stator. Started it up and drove it around and it ran great. Started it 15 times at least - no problems. Went out to get some gas an 15 minutes later - it wont' start again.
Could the kill switch be my issue? Will the motor turn over if the kill switch is open? What's the best/easiest way to isolate the kill switch from the motor?
Or - is there somewhere else I should be looking?
Thanks - John
