What changes were made to improve new water pump, and cooling system?
I'm assuming the new LU configuration improved suction to the water pump.

Tohatsu completely redesigned the entire cooling system. It's more like Mercury's cooling system than the old tohatsu's. My 4 stroke will pump right at 23 pounds at 6100 rpm, 4-5 pounds at idle. My old race motors, stock 50hp tohatsu's, would pump 9 pounds at 7400 rpm, about 1/4 pound at idle. I have had this 4 stroke water system completely plugged twice in the year of marsh fishing, not bad.
