I'm having same issue here with a 88 mercury xr4 black max 150hp. All of a sudden have lost spark, if I disconnect these 2 wires and get spark back can I leave them undone? Thank you.

No. If you do that you won't be able to turn the motor off from the key. You would need to troubleshoot to find out why the black/yellow wire is being grounded.

I did remove each kill wire. Got spark back to starboard bank none in port. I took wires from stator and swapped the fire followed. Now spark on port side none to starboard. Leading me to believe stator is good but a bad switch box?
If you swamped the wires coming from the stator (not the trigger), and the problem moved to the other bank, that would indicate a problem with the stator. Sounds like one of the outputs to the switchboxes is not supplying power. It's not the switchboxes because those are still attached to the same bank's ignition coils. They haven't moved.

Thank you for the replies and help. This is my 1st real outboard motor and bass boat. I moved the blue amd red wires from stator and swapped them to the other switch. Just got someone here amd fire stayed on same bank. So switch seems to be working and now looking like a stator issue.
