Say check this out. I have a vip boat with a Force 125 hp outboard. I had what sounds like the same type of problem you're having. I wasn't getting any spark on any 4 cylinders. I was told the same thing about a kill switch. Never found one. I did research on this and it took several days of painstaking research. Every where I would turn I was led to the stator. So, I'm not the type of fella who starts throwing money at parts just to see if it fixes it. I did resistance checks on my coils first. Primary and secondary checks compared each reading I got from all coil packs. They were all real close to being the same. Then the next in line was my stator wires and the big square diode (rectifier). Stator wire readings were inconsistent with what was stated. Ta DA. I changed out the stator, problem solved! If you're not familiar with doing these checks for resistance and so forth, just keep doing research and you'll find what you need after some extensive work. Electrical things associated with ignitions are not all that easy for some as it can stump me also, and im certified in the electronics field. Be patient but persistent and it will pay off. The stator is under the flywheel and it gives it voltage to fire the (cdi) box which in turn multiples this voltage to charge primary of coil so that it collapses onto secondary before completing the cycle an
lighting up the sparkplug. Good luck and let me know if this has helped...
