Yamaha 6G6-85540-00-00 CDI Unit Assembly

The Yamaha 6G6-85540-00-00 is an OEM Capacitor Discharge Ignition (CDI) unit assembly designed as the electronic control module for Yamaha 150 horsepower 2-stroke outboard motors manufactured between 1996 and 1999. This component manages ignition timing advance curves, rev limiting, and spark delivery for the engine's six-cylinder configuration. Constructed with a sealed aluminum housing to withstand marine environments, the unit features an OEM-specific multi-pin connector for direct plug-in installation. It replaces the original factory ignition control module without requiring wiring modifications. The assembly integrates the ignition coil driver circuits and microprocessor-based timing logic calibrated specifically for the 150HP 2-stroke powerhead. Compatible with engine models including the C150TXRW (1998) and other 150HP variants within the 1996-1999 model year range. This is a genuine Yamaha Marine service part.
