The ignition coil serves a similar purpose as a transformer. The ignition coil uses two coils (one inside the other) to transform the electrical energy from the engine battery to high voltage. It stores the electrical energy prior to releasing a high voltage current to the spark plug.
Ignition coils' purpose is to provide the spark plug an electrical pulse so it may jump the gap and produce a spark. The marine coil performs the same job as its automotive counterpart. This necessary part transforms the battery's electricity into the voltages needed to light the plugs. This spark then ignites the fuel, keeping your engine running. The marine coil performs the same job as its automotive counterpart. These components do not require maintenance other than replacing the spark plugs and their wires.
