ABSTRACT:
In a marine propulsion system including an internal combustion engine driving a voltage generator (14) supplying system voltage (line 26) which is supplied to ignition circuitry (10) providing spark ignition for running the engine in normal operation, overvoltage protection is provided for both the voltage generator regulator (12) and the ignition circuitry. If sensed system voltage is below a given threshold (V.sub.T), normal operation of the engine is continued. If sensed system voltage is above the given threshold, engine speed is reduced to reduce the generated voltage.
