The Sierra 18-99166 Power Pack is a high-quality replacement ignition module designed for Johnson and Evinrude outboard motors. This electronic power pack controls the ignition timing and delivers the proper voltage to the ignition coils, ensuring reliable engine starting and smooth operation.
Key Features:
Power packs are critical to outboard engine performance, as they regulate the electrical charge sent to the spark plugs. When a power pack fails, symptoms typically include hard starting, loss of power, misfiring, or complete engine failure. This Sierra replacement unit restores proper ignition function and gets your Johnson or Evinrude outboard running smoothly again.
Great price and quick shipping!
