Re: power pack or not
On the number cylinder, it is most likely coming from the pack. I had the same problem on my boat. It turned out the whole pack was bad. I have a 175 johnson with one power pack, and the whole left side wasn't working. With yours, make sure all the connections are good and the wires are still attached where they're supposed to be. Check the book to see about testing just the pack. If it tests good, it might be a bad ground or somewhere else.
