The only thing that is belt driven under the power steering pump is an alternator. If your battery is low and the alternator is on full charge they will get hot.

Need pictures.

If it has a serpentine belt, it ain't 1993! We didn't see serpentines until the gen+ engines, late '96. If there is a pump under the power steering pump, then it may be either a seawater pump for a Bravo drive or a seawater pump for a closed cooling system used in water over 26C. Either way we need serial number or photos, or both.... And the only reason one of those pumps gets hot is a lack of water. Does it have a thru hull water pickup? or a transom mounted water pickup?
