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.
Shop at Marine Parts Source whenever you need a CDI ignition kit that fits your engine. We are an authorized CDI Electronics dealer with various Mercury/Mariner switch boxes in stock and many more available. From small two-cylinder outboard engines to their most powerful four- and six-cylinder motors, we will help you find the right CDI ignition module at a great price. Many of these kits qualify for free U.S. grounding shipping to give you bigger savings.
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.
Click on an ignition pack to see a list of OEM models and serial numbers it is a direct swap for. The module will ship from the nearest in-stock warehouse. Browse our full selection of CDI marine products for more Mercury Mariner outboard solutions or contact us if you need assistance.
