What's Included

1 × Ignition Coil

This listing is for ONE ignition coil only.

Please note that multi-cylinder engines normally require multiple ignition coils.

⚠️ Important Compatibility Warning

This coil does NOT fit every Johnson / Evinrude 4–300 HP engine.

Johnson / Evinrude used several different ignition coil designs across similar horsepower and year ranges.

Before ordering, please check:

Original ignition coil part number
Engine horsepower
Engine model number
Model year
Electrical connection
Mounting arrangement

If the coil looks the same as yours, this does not always mean it is the correct part for your outboard.

If unsure, send SSI Marine your engine model number + horsepower + year if known and we will help check compatibility.

Important – Different OMC Ignition Coils

Please do not confuse 582508 with other Johnson / Evinrude ignition coil families such as:

584561 / 583737 / 582366
583740

These are different OMC ignition coil families used on other applications.

For example, Sierra identifies:

18-5176 → 582106 / 582330 / 582366 / 583737 / 584561
18-5179 → 582508
18-5170 → 583740

These should not automatically be treated as interchangeable.

Buyer Responsibility

It is the buyer's responsibility to confirm compatibility before purchasing.

OEM part numbers are used for identification and reference purposes only.

Correct diagnosis is recommended before replacing ignition components, as power pack, stator, timer base, wiring, spark plug or other electrical faults can cause similar symptoms.
