1989 E88MSLCER No Spark Cylinder 4

[drobertsobx]

Hi guys,
Just got off the water the motor felt sluggish.
Did a spark test and had no spark on #4.
I replaced the coil, no joy.
I then swapped coil charge input from #2 to # 4 had good spark, verifying the new coil was good.

Am I suspecting the power pack not sending charge voltage? or something else.

Thanks Don

A new powerpack is usually the solution.

Thanks for the speedy reply, I figured but thought I would ask the pros. Guess I'm spending more money on her today

That solved it, replaced power pack with OEM and all 4 coils, also replaced all plugs with the QL77JC4's gapped .035, starts up on the first cylinder that comes to the top every time again.
Must have been weak spark throughout, idle jumped up to 1600 or roughly +700 RPM on the initial start with all new components.
I set it for 900 on the hose in the driveway should be about 650 in fwd. gear at idle in the water if memory serves.
