Sierra 18-99213 Johnson/Evinrude CD2 Power Pack Conversion Kit, Replaces 584984, Fits 2-Cyl 4-55 HP (1988-1995)

The Sierra 18-99213 is a CD2 power pack conversion kit built for 2-cylinder Johnson/Evinrude outboard engines. It serves as the ignition control module that manages the capacitor discharge (CD) ignition system, replacing the original power pack when it fails or when converting the ignition system to CD2 specification. The housing is constructed of aluminum for durable mounting and heat dissipation in the outboard's powerhead area.

This power pack is designed for 2-cylinder, 2-stroke gasoline outboard engines and fits transom-mount applications. It is engineered as a direct replacement for a wide range of Johnson/Evinrude OEM power pack part numbers, making it a straightforward swap for engines built between 1988 and 1995 across the 4 through 55 horsepower range. The kit weighs 1.38 pounds and is supplied as a single-unit assembly ready for installation onto the compatible powerhead.
