So on smooth water your coolant temperature is 138 -142 at WOT and in "1-2 foot chop" it is 160F at WOT? Is that correct?

What is the oil temperature number at WOT?

I tee off the main water line.. just after the raw water pump. This is where Dustin Whipple told me to do it. He told me that this should work, and had me modify the nose on my drive also in order to get more water flow when trimmed up.

He said that if this didn't work on my particular boat, that I should put a transom pickup with a seperate water strainer for the innercooler, and just run the water for the motor thru the outdrive.
