92 Johnson 100GT V4

[HydroPower]

I have a one out of four cylinders firing. As you look at it, its the bottom right cylinder. Tried changing coil and plug still no spark, so swapped power pack wire to coil to just see if I could get spark at that coil and it did.(put back after to original position) It will start and run but will only get to about 3500rpms. I have checked the flywheel and magnets are all good!
Please any help would be appreciated before I go buying a new power pack, to try.

I could be way off, but reading as I did, you have a dodgey power pack.
