Ignition Coil 33410-93E10 33410-94400-000

Function and technical context

The ignition coil is the component responsible for transforming the battery voltage into the high voltage necessary to generate the spark at the spark plug, thereby initiating combustion in each cylinder. It operates within the outboard engine ignition system, working in close coordination with the ignition module, magnetic flywheel, and high-tension wiring. A faulty coil causes ignition misfires, difficult starting, or complete engine failure to start, directly affecting the performance and reliability of the vessel. This reference is compatible with Suzuki outboard engines of the DF and DT series, as well as equipment from the OMC family, covering a wide range of applications for recreational and professional use on inflatable, rigid inflatable, and pleasure craft.

When to replace this part?

The most common symptoms of a faulty ignition coil include jerking or intermittent cutting at different engine speeds, misfire in one or several cylinders, difficulty starting in cold or hot conditions, and spark plugs that do not fire even though they are in good condition. It is recommended to inspect the coil at each seasonal maintenance service, especially if the engine shows irregularities at idle or unexplained power loss. Replacing the coil preventively at the first symptom avoids becoming stranded at sea and protects the rest of the ignition system from overloads caused by a deteriorated component.
