Product Details

This aftermarket CDI power pack is designed for selected Johnson/Evinrude 2-cylinder, 2-stroke outboard ignition systems rated from 4 to 60 HP and manufactured from 1977 through 1984. The catalog application identifies this power-pack design as having no built-in RPM limit.

It is listed as a replacement for the OMC ignition-module numbers shown below. Confirm the engine's exact model, year, cylinder configuration, wiring and original power-pack number before ordering, because horsepower and year ranges alone do not confirm fitment for every engine.

  • 2-stroke ignition-system application.

Troubleshooting & FAQ

What engines is this power pack intended for?

It is intended for selected Johnson/Evinrude 2-cylinder, 2-stroke outboards rated from 4 to 60 HP and covering model years 1977–1984. Exact model and serial-number verification is recommended before purchase.

What original numbers does this power pack replace?

The listed OMC replacement references are 581649, 583380, 583453, 581924, 581926, 581927, 582452 and 582453. CDI reference 113-2453 and Sierra reference 18-5758 are also associated with this application.

Does this power pack have an RPM limiter?

The catalog application for this power pack is listed as having no RPM limit. This does not change any separate RPM limits or operating requirements specified by the engine manufacturer.

Will this automatically fix a no-spark problem?

Not necessarily. No-spark and intermittent-spark conditions can also be caused by the stator, trigger, ignition coils, wiring, grounds, connectors or other ignition components. Test the complete ignition system before replacing parts.

Is this an OEM part?

No. This listing is for an aftermarket replacement power pack. The OEM and aftermarket reference numbers are supplied only to help verify the intended application.

Can I install it myself?

Installation should be performed only by someone familiar with outboard ignition systems and the correct service information. Disconnect power before working on the wiring and verify all connections before testing the engine.
