ABSTRACT:
An internal combustion engine particularly adapted for driving a vehicle, such as a watercraft, that includes accessories and an engine management system for controlling certain functions of the engine electrically. In order to prevent misadjustment in the event of low available battery voltage, a number of arrangements are depicted for maintaining battery voltage when the normal battery voltage falls. This may be done by increasing engine speed when operating in neutral, discontinuing the operation of other accessories and/or switching a second battery into the power circuit. In addition, an arrangement is provided wherein a battery may be supplied for utilization in starting of the engine to avoid depletion of the main battery's voltage so that the engine control can be maintained even during starting.
