CDI Electronics 114-2986 Mercury/Mariner Ignition Pack - 4/6 Cyl (1967-1979)

I had to return this box to CDI (at my expense) 2 times & should have been 3. First time the coil was bad, 2nd time the box tested bad, and the last time a CDI tech told me they have been having a problem with the coils for several months and my current complaint sounded like a bad coil. Rather return the box for the 3rd time, I purchased a new coil and that fixed the problem. Save yourself time & aggravation and purchase a newer motor that you can get OEM parts for.

For now 4 stars. I'll revise my review in a year and hopefully the part holds up. I've had some electrical parts work great for a while and fall flat. I'm keeping my fingers crossed for this part.
