Ignition Coil - Sierra Marine Engine Parts - 18-5438 (118-5438)

An ignition Coil is (also called a spark coil) an induction coil that is to increase the low voltage of the battery (12 Volt) to a very high voltage ( about 50000 Volt) to produce a spark within the engine cylinder for the combustion of fuel. It is utilized in the ignition system of automobiles.

Coils keep boat motors cool. The marine coil functions similarly to the component in your automobile. This critical component transfers the power from the battery into the voltages required to ignite the gasoline, allowing your motor to run. This ignites the fuel, allowing your engine to continue to run.
