all of the above ,also if you have bravos, check for bravo fever, the inlet hose that runs from the gimbal helmut to the transom assy has that little nylon insert. sometimes the corrosion builds between it and the housing itself closing the inlet hose and she may run hot. also check for debri in the oil cooler on the inlet side. and chech all connections , especially on the suction side of the water system
.

good luck
