688-85540-16 Electronic Ignition CDI
Yamaha Outboard Engine Electronic Ignition System
Stable Ignition · Reliable Starting · Durable Operation
Designed to Original Equipment Dimensions – No Modification Required
The 688-85540-16 CDI is an electronic ignition control unit used in Yamaha outboard engine ignition systems. It receives engine trigger signals and, according to the ignition control characteristics, drives the high-voltage ignition coil to generate a high-voltage spark, providing stable and reliable ignition control for the engine.
Designed for the demanding operating conditions of outboard engines—including long-duration operation, humid environments, and engine vibration—the CDI uses electronic ignition control technology. When combined with a suitable high-voltage ignition coil and trigger system, it provides stable and consistent ignition performance.
Product Features
Stable Electronic Ignition Control
The CDI electronic circuit controls ignition timing and rapidly processes engine trigger signals to provide stable ignition output.
Designed for Outboard Engine Ignition Systems
Designed for ignition systems used in Yamaha outboard engines. It can be used as a reference specification for original CDI repair, replacement, and electronic ignition component development.
Original-Specification Replacement
Using 688-85540-16 as the product identification reference, the CDI is suitable for repair-market applications and electronic ignition component replacement.
Suitable for Marine Operating Environments
Outboard engines operate in environments subject to moisture, vibration, and temperature variations. Therefore, the CDI housing and internal electronic components require good environmental resistance and durability.
Works with a High-Voltage Ignition Coil
The CDI does not generate the spark independently. It must be used together with a suitable ignition coil, spark plug, and trigger/pulse system to form a complete ignition circuit.
