Honda Description
MODULE, IGNITION CONTROL (CDI)
What Is the CDI Unit?
The CDI / ignition control module is an important part of the outboard's ignition system.
It controls the ignition system and helps ensure the spark is delivered at the correct time for proper engine operation.
A faulty CDI module can be associated with symptoms such as:
- No spark
- Intermittent spark
- Difficult starting
- Engine cutting out
- Misfiring
- Loss of ignition when hot
- Irregular engine operation
Important
These symptoms do not automatically mean the CDI is faulty.
Similar problems can be caused by other ignition or electrical components, so proper diagnosis is recommended before replacing the CDI unit.

⚠️ IMPORTANT – Check Your Exact Honda Model
Honda used different ignition modules depending on the exact engine model and specification.
Do NOT order this CDI by horsepower alone.
Before purchasing, please check:
- Exact Honda model
- Horsepower
- Model designation
- Engine serial number
- Original CDI part number
- Electrical connectors
- Wiring configuration
- Mounting arrangement
Ideally, match your original part number to:
30580-ZV4-023
30580-ZV4-013
or
30580-ZV4-003
⚠️ Appearance Does Not Confirm Fitment
If the CDI unit looks the same as the one fitted to your engine, this does not always mean it is the correct part for your outboard.
Different Honda ignition modules can look very similar externally but have different applications and electrical specifications.
If you are unsure, contact SSI Marine with your complete engine details before purchasing.
Before Replacing Your CDI Unit
CDI units are frequently replaced when an engine has a no-spark or intermittent ignition problem, but the CDI is not always the cause.
Before installing the replacement, we recommend checking the complete ignition system.
Check:
- Ignition coil
- Spark plugs
- Spark plug caps and leads
- Charging / exciter coil where applicable
- Pulse / trigger components
- Stop / kill circuit
- Engine earth / ground connections
- CDI wiring
- Electrical connectors
- Burnt or corroded terminals
- Damaged or melted wiring
A fault elsewhere in the ignition system can produce symptoms similar to a failed CDI module.
