Abstract
A marine propulsion engine abnormal condition sensing arrangement, specifically a low oil pressure sensor, that is effective to permit a low cost sensor by using a separate power supply circuit that need not pass through the main watercraft control in order to drive the switch. The warning device that is operated by the switch is provided with a separate power supply so that its characteristics need not determine the current that is supplied to the sensor.
