Jay,

I have never seen any data to answer your question, but it seems not  
to be critical. I have been told that only a very small flow is needed  
to cool a (conventional) motor and that it the danger lies in  
stagnation and warming of water around the motor when not confined in  
a flow-inducing tube.
