Hello all, first time poster here. I am usually good about fixing engine problems myself but this one has me stumped. At times my motor has no spark going to all three cylinders. This has happened a few time since I have been getting the boat ready for spring. It has fired a few times but the past two days no spark. Spark has been checked with inline spark tester as well as holding plug against block. This happened a few years back and I disconnected kill switch and it solved the problem. I tried that yesterday and still no spark. I have gotten on CID electronics and downloaded their troubleshooting guide. All of the ohm measurements are within spec but I do not have a fancy meter to read the voltage, just a cheap multi tester. What should my next step be. Could it be the pack? Stator? Are there any other things I can check before I take it to a mechanic for him to sort out. Just trying to rule out before I take it in. My gut tells me power pack but I do not want to order one if that's not the issue. Thanks for any help you can provide.
