Suzuki Motor Corporation 32900-87D20 CDI Unit

The Suzuki 32900-87D20 CDI Unit is a genuine Suzuki OEM ignition-control module for two-stroke outboard engines, designed to regulate spark timing and discharge to the ignition system. As a 32900-87D20 designation, it is listed in Suzuki's parts catalogs and by OEM retailers as a direct replacement CDI unit for older DT-series Suzuki outboards from the mid-1980s. Because it is an OEM replacement, fitment should be confirmed against your engine family and model year with a Suzuki dealer or service manual to ensure compatibility. Used in vintage DT-series two-stroke outboards, this CDI unit helps restore reliable starting and consistent firing by coordinating the ignition timing with the engine's ignition coils.
