Cdi Electronics Mercury Mariner Switch Box Cylinder Ignition Repair Parts

CDI Electronics switch boxes are replacement outboard ignition components. They are also called CDI power packs or ignition switch boxes. They are built for Mercury and Mariner outboard motors. The switch box is the electronic module that controls spark timing and delivers the high-voltage pulse to the ignition coils. It is a common repair part when an older outboard has weak spark, misfires or no spark.

Key Features:

• Aftermarket replacement switch box and power pack for Mercury and Mariner outboard ignition systems
• Cross-references to the original Mercury and Sierra part numbers listed for each part number in the line
• Designed as a direct replacement for the original unit, so installation is simple
• Made by CDI Electronics, a maker of electronic ignition systems and marine ignition components
• Covers the 2 cylinder and 4 cylinder applications in this product line

Choose the individual part number that matches your original Mercury or Mariner part number. This confirms the right fit for your outboard. Replacing a failing switch box can restore reliable starting and smooth running.
