This video is from an outboard engine survey that I conducted on August 31, 2016. The outboard engines surveyed were two Mercury Opti-Max 225 HP outboard engines. The starboard engine had a dead ignition coil on cylinder number five. It was not obvious to tell at first look when the engine was running or even during the sea trial because the ECM had long since compensated for the loss of the ignition coil. There were some things I noticed that made me suspicious during the inspection to start checking the ignition system of this outboard engine. The dead ignition coil was discovered and confirmed by using a digital inductive meter and verified by the diagnostics computer when testing each ignition coil by shutting them off individually with the diagnostics computer. You will see in the video that there is no change in the number five ignition coil because the ECM had already compensated for the loss of the ignition coil with the remaining functioning coils. In a typical marine survey this would have been completely missed. This is the difference between a well trained marine surveyor who has the knowledge, training, education, understanding of how marine engines work who also has the proper tools and equipment versus a surveyor that does not have the proper education, understanding or even fully knows how to use inductive electrical equipment and diagnostic computers to find these propblems.
