I have a 1996 Tracker outboard runs rough. Found no spark #1 cylinder. Replaced coil then no spark # 3 cylinder right after I replace #1 coil. Motor seems to have a mind of its own. I replaced CDM and all 3 coils prior to this issue because motor was doing the same thing. Compression is 110 across all three cylinders.
