Sierra Power Pack – Johnson & Evinrude Outboards
Restore crisp, reliable ignition to your Johnson or Evinrude outboard with this direct-replacement power pack. The power pack is the heart of the capacitor discharge ignition (CDI) system — it generates and delivers the high-voltage charge that fires your spark plugs. When this component fails, symptoms range from hard starting and misfiring to complete no-spark conditions. This Sierra unit is built to OEM specifications for a dependable, drop-in fix.

Parts Desk Insights
This power pack is the go-to solution when a Johnson or Evinrude outboard has lost spark entirely or is misfiring under load — especially after ruling out spark plugs and plug wires as the cause. It's a common wear item on older CDI-equipped outboards and is best addressed as part of a full ignition inspection. Before ordering, confirm your engine's model number and year to ensure correct fitment — power pack compatibility is model-specific and varies across horsepower ratings and production years. When in doubt, cross-reference against the Sierra application guide or contact us with your engine's serial number.
