This CDI (Capacitor Discharge Ignition) module is a direct replacement for the ignition module fitted to Yamaha 9.9HP to 25HP outboard motors built between 1984 and 1997. It stores electrical energy and discharges it to the spark plug at precisely the right moment in the ignition cycle.
It is engineered to the same fit, wiring and performance as the original Yamaha module, and built to cope with the heat, vibration and moisture found in a marine engine environment.
