Last time out I had cylinders dropping out at an idle but would kick in when I throttled up a little. I figured it was plugs fouling do to running double oil because of rebuild. I changed the plugs and I have no spark on one bank of cylinders. I’m thinking it’s the power pack on that side but a friend mentioned the shift interrupter switch but as far as I know there isn’t one on that motor. I pulled the black and yellow wire and no change.
anyone know of any other possibilities? I hope to be on the water this weekend. The motor has been running flawlessly up until last time out.

I picked up a new power pack but when I went to install it I found the problem. One of the connectors must not have had a good connection and burned up. I cut out the connector and soldered the wires together and have spark now.
