Mechanic's Assistant: Sometimes things that you think will be really complicated end up being easy to fix. The Marine Mechanic I'm going to connect you with knows all the tricks and shortcuts. Tell me a bit more about what's going on so the Marine Mechanic can help you best.

Have 1984 ,50 hp merc, was running well, set for a few months, lost spark on # 4, changed coil packs on 3 and 4, changed switch box, now only have fire on 3, have any ideas? thanks, *****: Is there anything else the Marine Mechanic should be aware of?

I think that covers it. The engine was running on three cylinders till I started changing parts.

Okay got it. Now where you looking to do step by step troubleshooting with a volt meter together, right now? Or did you just need me to explain all of the things that can cause a lack of spark on 1 cylinder?
