ABSTRACT:
A warning system for an outboard motor, includes: an oil-pressure switch for outputting the low-pressure state signal when the oil pressure of the lubricating oil lowers than a fixed reference pressure; a control device for controlling the operation of the warning device; a determining device which judges whether the low-pressure state signal continues to be output longer than the predetermined delay time and determines that the oil pressure is abnormal if the judgment is affirmative; and a control device for actuating the warning device so as to perform a warning operation when the determining device has determined that the oil pressure is abnormal.
