Sierra 18-99282 CD Power Pack for Johnson Evinrude Outboard Motors, Replaces CDI Electronics 113-2705

The Sierra 18-99282 is a capacitor discharge (CD) power pack built for Johnson Evinrude outboard motors, serving as the ignition module that generates and delivers the spark energy needed to fire the engine's cylinders. As a core electrical component in the outboard's ignition system, the power pack works alongside the stator, trigger, and coils to keep engine timing consistent and starting reliable. This power pack is offered as a direct cross-reference to the CDI Electronics 113-2705 unit, making it a straightforward option for boat owners and marine technicians replacing a failed or aging power pack without hunting for an obsolete original part number. It is a compact, lightweight unit at 0.6 pounds, designed to mount into the existing wiring harness location used by Johnson Evinrude ignition systems. Whether you are restoring an older outboard or simply replacing a worn ignition component during routine maintenance, the 18-99282 is built to restore proper spark output and help the engine start and run the way it should.
