What does an ignition coil do on a boat?

Ignition coils are unique to an engine family. Its function is to provide an electrical pulse to the spark plug that jumps the gap creating a spark. The switchbox provides the voltage and current to the coil along with the signal for the coil to fire.

Will a poor ignition coil damage the engine?
