I have a 2005 90hp 2 stroke that I am having issues with. Started out surging at higher rpms...seems to run smooth at lower rpms. Installed new plugs, no help, got a new CDM module and did the typical swapping out of the 3 and no difference...Not sure what to look at next. I ran it yesterday on the water and pulled the cover off. Top two rubber boots on the spark plug covers were very hot to the touch...bottom plug was not hot at all. I also pulled the plug wires off while running...top two throw a spark a long way, bottom plug only tries to spark when the boot is almost completely on. No long throwing of a spark like the top two. Also I have 2 yellow wires coming off of the regulator that looked to be burned or have gotten hot where the clear connectors are. Should I be worried about this? Thanks for any help.
