help!! i have a 1986 mercury 115 hp in line 6 with no spark in the second cyl. boat ran fine for about a half hour then no power. at idle i pulled each plug wire and found # 2 wasn't "throwing" a spark.

Re: no spark in #2

Figure out if the rest of the plug wires/coils produce a spark, and then get on the CDI.com or Dolphinmarineservices.com web sites and look for the troubleshooting guide for your ADI ignition.
