Had an issue with my 40 hp mercury 2 stoke it wouldn't get over 2200 rpm on water. Rebuild carb and fuel pump and line and fixtures. No help. Noticed top plug wasn't getting warm.. tested and no spark. Switched # 1 & #2 cdm and got same result so figured cdms are good. Any ideas.

Mechanic confirmed if cdms are good then he will test for trigger or stator malfunction. I will keep u updated.

Easy test is to unplug #2 and if fire returns to #1 the #2 module is bad even though it may be sparking. If it still dont fire reconnect #2 and unplug #3, if #1 starts sparking #3 module is bad.
