IGNITION COIL 95188T REC6E7-85570-19

Function and technical context

The 95188T ignition coil is an essential electromechanical component in the ignition system of marine petrol engines. Its main function is to transform the low voltage current from the engine's electrical circuit into high voltage voltage, essential to generate the spark in the spark plugs and achieve the correct combustion of the air-fuel mixture in each engine cycle. This part works within the ignition system, where any failure immediately compromises the reliability of the start and the operation of the engine. A deterioration in the coil causes loss of power, cold starting difficulties and, in advanced cases, the inability to start the boat.

When to replace this part?

Typical symptoms of a faulty ignition coil include weak or absent spark, engine that starts hard especially in wet conditions, loss of revs under load and intermittent misfires. Although there is no fixed replacement interval for ignition coils, it is recommended to inspect their condition at each seasonal inspection and, especially, if the engine shows erratic behavior or does not start correctly. Preventively replacing the coil when symptoms are detected avoids unexpected stays in the water and more expensive repairs resulting from damage to other components of the ignition system.
