    1989 Mercury Blackmax 150 no spark

    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.

    1989 Mercury Blackmax 150 no spark

    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?

    1989 Mercury Blackmax 150 no spark

    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.
