I put in a new power pack on my 1987 88hp Johnson because I was having some misfires at mid to high rpms. Now i don't have spark on cylinders 3 and 4. I was pretty sure the original power pack was the problem because there was rip in the coil fitting boot and I could see the terminal. If one power pack doesn't get voltage could it be the stator or would you suspect a bad power pack?
