Noticed after a few trips and low top end power that the top cylinder appears to not be firing. Upon inspection of new plugs after a full 3 plug change early this season saw that the top plug is clean and was wet with fuel.
The other 2 plugs have carbon.....also can note that the boat would not get up on plane without weight shifting to the bow and then WOT speed was about 5 mph lower than normal.
Also note that I changed plugs again to make sure the plug was not bad - same problem.
I checked the plug wire for the top cylinder and it showed continuity (basically 0 ohms). Checked the coil primary which was 0.5 ohm and secondary which was 875 ohms. Cylinder below it was 0.4/0.5 on primary and did not check secondary because that one was firing OK.
Do I have a bad coil - or do I need to do further troubleshooting to determine what the problem is??
Thanks in advance!!
