"I have an older Merc 7.5 ser
"I have an older Merc 7.5 ser #3104046 So I've checked the kill switch - grounded unless pressed - working fine. Check, removed, cleaned the points. Reinstalled them with a .020 gap. With a meter I found that they were opposingly grounding and ungrounding the coils. I cleaned the stator surfaces. Also cleaned all wire connections to the coils. Oh and obviously installed new plugs. Still no spark. That leaves the stator and the coils. Well it is unlikely that both coils would go at once. So I'm guessing its the stator. I've tried to see if I get any juice out of the stator but am not really sure if I am testing it correctly. I found a part on this site that looks exactly like my stator but I am unsure if there are certain model years that this part fits. This is the part number "18-5855". I am not sure if I want to put $300.00 into this motor. Before this "breakdown" the engine was running great. First pull starts! Should I check anything else? I've scanned through previous posts but I didn’t find anything on this subject. I hope its not a repeat post."
