Troubleshooting & FAQ
Q: How do I confirm this CDI unit fits my Suzuki outboard?
A: Check the compatibility table above to verify your engine model (DT9.9 or DT15) and year (1986–2012). Cross-reference the OEM part numbers 32900-93910 or 32900-93911 with your engine's service manual or parts diagram.
Q: What are the signs that my CDI unit is failing?
A: Common symptoms include difficulty starting, intermittent misfires, loss of power at high RPM, or the engine cutting out unexpectedly. If spark plugs and ignition coils test normal, the CDI unit is often the culprit.
Q: How often should I replace the CDI unit?
A: CDI units typically do not require routine replacement and should last many years under normal conditions. Replace only when you experience ignition-related failures or following a lightning strike or electrical surge.
Q: Can I install this myself, or do I need a mechanic?
A: Installation is straightforward if you are comfortable with basic electrical connections. However, professional installation is recommended to ensure correct fitment and avoid potential ignition system damage.

A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.
Q: How fast do you ship and how much does it cost?
