A monitor and alarm system is provided for a marine vessel having a rotatable propeller drive shaft supported by one or more water-cooled bearings contained in strut barrels mounted on struts extending from the vessel hull or in stern tube assemblies. A heat sensor on the hull senses the ambient temperature of the water surrounding the vessel and one or more sensors on one or more bearings sense the temperature of the bearings. The sensed temperatures are electrically communicated via wires or wirelessly to gauges for monitoring and to a processing unit. The processing unit compares the sensed temperatures and generates a signal to an alarm device to initiate a bearing overheat warning or alarm if the differential between the bearing temperature and the ambient water temperature exceeds a predetermined amount.
