Sounds like Rods hit the nail on the head.
Did you notice during the overheat times was there water coming from both left and right side pissers?... If not.
I'd check all your water lines for restrictions. Including the inlet screen in the side of the pump. (4 bolts on left side of the pump)
If they were working strong then I'd check out the temp switch. And there is still the possibility the exhaust water passages are restricted/clogged causing poor water flow.
Has this has always been a freshwater ski? Does it get regular flushing on the hose?
