1965 Johnson Outboard 75hp No Spark Problems

[magyver]

I just bought a boat with a 1965 75hp Johnson Outboard. I'm not getting any spark to the plugs. I'm not getting any spark from the coil either. I have tried so many things that I have read on here and other sites. Can any one please help me? The model# V4AL-17S. Thanks
