Mercury/Mariner Outboard CDI Ignition Packs

For decades, CDI has been a manufacturer of ignition packs for Mercury Marine and Mariner outboard motors. Sometimes called power packs, switch boxes or ignition modules, these components improve engine performance by automatically regulating ignition timing so the system sends the most intense spark at the exact moment needed for combustion. By using a genuine CDI ignition module, your Mercury or Mariner engine will start and run smoother with more power and efficiency.

We are an authorized CDI Electronics dealer with various Mercury/Mariner switch boxes in stock and many more available.

Update Your Outboard Ignition System

CDI doesn’t just recreate its factory-quality ignition packs and call it a day. Before manufacturing replacement ignition modules, they identify any issues with the original component and improve on them with better materials and design. The result is a CDI ignition pack that works even better than the part it’s replacing.
