Systems and methods are for monitoring an operational characteristic of a pump pumping cooling water from upstream to downstream to cool a marine engine. A sensor senses a characteristic of the cooling water at a location that is downstream of the pump. A control circuit is in communication with the sensor and receives the sensed characteristic of the cooling water, compares the sensed characteristic of the cooling water to a stored nominal value, and determines a present operational condition of the pump based on the comparison. |
