CDI Electronics 113-2125 Power Pack CD4, Johnson Evinrude 85-140 HP 1978-1984, Replaces 581805 582125 582454

The CDI Electronics 113-2125 is a CD4 power pack built for Johnson and Evinrude outboards, replacing the original ignition power pack on 85, 90, 100, 115, and 140 HP engines from 1978-1984. It provides capacitor discharge ignition control with no RPM limit, delivering full-range spark output across the engine's operating range. Two power packs are required per installation on the engines this part fits. The orange ignition coil wires plug directly into the wiring harness coming from the ignition coils, allowing for a straightforward connection during replacement. This part has been discontinued by CDI Electronics and is superseded by the Sierra 18-5759-1 CDI replacement power pack, which is the current part supplied for these same Johnson/Evinrude applications. The power pack is a direct cross-reference replacement for a wide range of original Johnson/Evinrude and OMC part numbers, making it straightforward to identify against an old, worn, or failed unit pulled from the engine. Installation instructions are available for reference when wiring the replacement pack into the existing harness.
