the dreaded no spark on 120 Mercruiser I/O

[mrmoore]

I bought a 1986 Cobia 193VBR with a 120hp I/O. I'm not getting any spark to the plugs. At the suggestion of a decent local mechanic that I know, I've replaced the coil, condenser, points and rotor. Still no spark. My test light is lighting on the negative side of the coil and lighting at the condenser wire. The motor cranks but I'm getting no spark whatsoever.
According to the previous owner, they NEVER had any problems (intermittent or otherwise) starting it which was about two years ago before they stopped using it.
Where do I go from here?

Thank you.
