I have found that the bottom cylinder is not running the coil is bad I need new coils and spark plug wires. I do not know the year of the motor to be exact I have the motor to be heavily painted and I cannot see any numbers. it also has a dial for air fuel mixture low speed and also has trolling speed adjustment on throttle. boat 1.jpgboat 2.jpg

Ok cool. I determined that the coil was bad by swapping the wires. I know that each coil is meant for one or the other cylinder, so when I tried to start it it backfired because of the wrong wire. When the wires are in original position, the one cylinder doesn't even fire...so I know its shot. Is my reasoning right? Thanks for the quick reply
