1985 Yamaha 115ETLK. I have no spark on # 3 cylinder. I swapped the coil from # 4 to # 3 and still no spark. Any opinions would be appreciated.

Re: Yamaha 115, no spark on #3 cylinder

Update to the story, I found that coil # 3 is bad. Would this possibly cause an overload in the cdi box causing me to not get spark to any plug. The reason I ask is that when I get on the water the motor seems to run fine but when put under load it will instantly die and I have no spark to any plug.
