Marine spark plugs generate spark by high voltage electricity at one end and release it at the other. The spark production is the combustion that propels your boat. It ignites the air and fuel mixture inside the engine.
The spark ignites the gasoline and air mixture and causes the explosion that propels your engine into action caused by spark plugs. These tiny, straightforward plugs produce an electrical arc across two leads that are not in contact but are close enough to one another for the energy to cover the distance between them. Without spark plugs, combustion in the engine bay is impossible. The components involved in the motion system will not operate.
