1991 Force 150hp- no spark, #5 cylinder??

[gregr1971]

I have a 1991 , 150hp, lost spark on #5, i have replaced the stator, due to it "sparking" while running , under the flywheel, stator had a burnt spot where the brown/blue wire comes off the stator, also replaced the cdi box for #4 & #5 cylinders, and the coil for #5.
now i am stumped??????

Is the trigger sending a signal to fire the cd ?

I had a few problems with the power pack droping cyl on my 91 150 . Do you have the thunderbolt system ? If so they tell me that you should replace both the power pack and the dc voltage box that feeds the pack together

no thunderbolt, it has the other system with the 3 blue powerpacks, and 9 milion wires.
ok, got the new timer base, not the problem, now it fires intermitently on 3 & 5, after it warms up. ???????????
1,2,4 are fine.
