I have a 1978 Johnson 85HP OB that is running on two cylinders, I swapped the power pack from the working side to the non working side, and that side started worked, so I purchased a new power pack and installed, all four cylinders worked for about 15 min. and then the power pack that I had swapped to the non working side failed again.
Any ideas what would cause a power pack to fail, I just got the motor and the power pack was out when I got it.
Thanks

Are you sure the power pack is at fault? Check the stator and the timer base. Maybe one of them is not to spec. Check them vs the specs in the ignition troubleshooting guide at this website: cdielectronics.com
