Important – Check Your Existing CDI

Please check the CDI fitted to your engine BEFORE ordering.

Yamaha used different ignition units across engines with similar horsepower and year ranges.

Your existing unit should correspond with one of the listed 695-85540 references or TIA01-36.

Please compare:

CDI part number
Electrical connections
Wire colours/configuration
Number of wires
Mounting points
Engine model
Engine year

Do not order by horsepower alone.

What Does the CDI Unit Do?

The CDI – Capacitor Discharge Ignition – unit is an important component of the outboard ignition system.

It controls the electrical discharge used to trigger the ignition coils and produce spark at the correct time.

A faulty CDI can potentially cause symptoms including:

No spark
Intermittent spark
Loss of spark on one cylinder
Difficult starting
Engine cutting out
Poor running
Irregular ignition

IMPORTANT

These symptoms do not automatically mean the CDI is faulty.

Similar symptoms can be caused by the stator/charge coil, pulser/trigger coil, ignition coils, wiring, stop circuit, connections or poor grounds.

We strongly recommend correctly diagnosing the ignition system before replacing the CDI.

⚠️ Important – Electrical Part

PLEASE DIAGNOSE THE ENGINE BEFORE ORDERING.

CDI units are frequently replaced when the actual ignition fault is caused by another component.

Before replacing the CDI, the relevant:

Charge/stator coils
Pulser/trigger components
Ignition coils
Stop circuit
Wiring
Connections
Engine grounds

should be checked as appropriate.

⚠️ Electrical Parts Returns

Please check compatibility carefully before opening, connecting or installing the CDI unit.

Electrical components that have been installed, connected or used cannot simply be returned as unused parts, as installation can make it impossible to establish their condition or whether another electrical fault has damaged them.

This does not affect your statutory rights where an item is faulty.

If you are unsure about compatibility, please contact SSI Marine before installation.

Important – Please Check Compatibility

Before purchasing, please confirm:

Yamaha outboard
Exact horsepower
2-stroke application
Engine model
Engine year
Existing CDI part number
Electrical connections
Mounting arrangement

The safest identification method is the existing CDI part number.

If the CDI looks the same as yours, this does not always mean it is the correct one for your outboard.

If you are unsure, please send SSI Marine your engine model, serial number and clear pictures of the existing CDI and connections before purchasing.
