Re: Are power packs repairable?
I fixed mine on my '76 Johnson '85. In de-potting mine, I bust the small leads off a couple of the coil drive SCRs. The SCRs were manufactured by Teccor Inc. but had proprietary markings on them. I eventually, came up with what I thought may be a suitable replacement SCRs. I did ultimately get the pack running, but I never tested it beyond running on the drive. Because I wasn't 100% sure of the SCRs, I bought a new pack anyway. I use the repaired pack as a backup now. Unless you have a decent amount of electronics knowledge and capability you are best off not attempting to repair your pack. I was surprised at the root cause of my pack's failure -corrosion. I had always assumed the encapsultion (potting) prevented any moisture ingress, apparently not so.
