Mercury 90 4 stroke ignition problem?
Need a bit of help with a carb 90 4stroke.
It has a misfire on 2 and 3. It has 2 coils. 1 doing 1 and 4 the other doing 2 and 3. IV swapped them and checked power out of them. 1 coil has no output. IV checked continuity all the way to the PCM and removed fly wheel to check pick ups under there. They both give with in a few the same ohms reading. Any ideas?
