can anyone possibly give me some advice! I have an 81 mercury 40 hp outboard that I have replaced the ignition stator, the switch box, and now I have a very very weak spark. The trigger tested at 740 ohms and it was so close to the low end of the specs I assumed it would work. Can anybody chime in and help me go fishing? Im new to this site so any help will be appreciated. Thanks :confused:

yes and I still have only a very almost nonexistent spark. In fact you can barely feel it if you hold the plug while you turn it over. I think I may have gotten a defective switch box. Any ideas?
