Re: 74 EVINRUDE no spark
I would get a manual and start in the electrical section. You will need a mutlimeter to do some of the test. Not sure, but if your motor has coils I would check them. The book will tell you how to do this task. I would do an ohm check on the coils and see if they are the same (or within 10% or so of each other. Good Luck.
