The CDI Electronics 18-99406 (replaces CDI 133-3378) is a 3-cylinder timer base assembly designed for Johnson and Evinrude outboard motors. This critical ignition component is located beneath the flywheel beside the stator and sends trigger signals to the CDI power pack, controlling ignition timing for optimal engine performance.

Key Features:

  • 3-cylinder timer base for Johnson/Evinrude outboards
  • Replaces OEM part numbers: 581949, 582724, 583060, 583131, 583378, 584269, 584562, and 778438

This timer base is a direct replacement for worn or damaged original equipment. Professional installation is recommended as it requires flywheel removal and proper timing adjustment. The timer base works in conjunction with the power pack to control spark timing on all three cylinders, ensuring reliable ignition performance.
