ABSTRACT:
An improved engine ignition system for a marine engine or the like, which provides reliable start-up capability. The system provides two timing characteristics for discharging a capacitive discharge ignition, one of which is advanced relative to the other. The advanced timing is invoked at startup and is switched to regular timing in response to the engine temperature reaching a predetermined temperature from a temperature switch and also as a result of a circuit having a thermistor near the engine. The thermistor circuit may operate if the temperature switch does not, due to debris or the like preventing proper operation of a thermostat.
