With twin 496 ho’s, Latham steering, do both motors control steering? Blew seal on port side, lost most of the oil. Can anything cause this to happen all of a sudden or it happens. Never leaked before. Pump got super hot, so I guess replace and not rebuild? Just wasn’t sure if both motors supplied steering, just towed in not to burn other pump.

Yes, they both have steering pumps but use a single reservoir. I once had a terrible noise coming from one and was able to put on a belt that routed around the pump and kept boating while waiting for a new pump. Only drawback would be if engine with the good power steering pump were to die.
