I have removed my thermostat checked those spring loaded balls and yes agree pressure does not equal volume. I am getting plenty of swirl in my strainer. I had even eliminated my strainer by going direct from the sea pump to the transom. Hitting temps of 190. took my outdrive off last night to check transom suction hose as well as the plastic adapter on the inside a slight corrosion build up on the inside but still was able to put my finger in the opening. Cant think of anything else WTF

Are you running a circulating pump? If so, maybe its bad? Also, are you sure the motor is really heating up or is it a bad gauge or sender? Have you tried removing the Tstat all together just to see if your still getting hot?

New circulating pump 2 years ago removed t stat and all new gauges from Livorsi this year I am assuming the gauge is correct due to the fact that running it at 4500 rpms temp went to 200 and alarm went off

I had a similar issue with my previous boat with B&M blowers and it turned out the supercharger snout was in need of service and it was getting hot. Being very close to the temp sender, it sent the temp reading up, although it didnt get quite as hot as yours. just a thought

I struggled with water pressure issues on my old 575 Fountain, this causing higher operating temps at 90+ mph. I ended up plugging a couple of holes in the lower (DWP), and that helped - but never really got it to where I wanted water pressure.
Have you checked water hose that runs through the transom? Those are known to corrode and close up the hole. Mine was ok. I replaced inlet hoses, sea pumps, removed coolers for flushing, etc. My next step was a water pickup on the transom, but sold boat before that happened.
