I have a 1967 Mercury 500ss ou

I have a 1967 Mercury 500ss outboard. Up until a week ago it started easy and ran well. It turns over but will not fire. It is getting plenty of fuel but appears to have no spark(Will be testing with a spark tester this evening). I am wondering if this motor has any kind of stop/saftey switch that may be faulty. I had mid-60's 50 HP that had an actual kill switch that did this. Any help would be greatly appreciated.
 
If it has the basic magneto yo

If it has the basic magneto you may have to drop it out and check / clean / set the points .Check for spark before you re-install.
