Hi Todd,

      Great to hear you have taken that on.  Leon and I exhanged a few views
on the suitability of the electric water pump for aircraft use and I
certainly respect Leon's experience and smarts - but, the bottom line is no
one (that we know of ) has yet tried one in an aircraft.  I will most
interested in what you find out.  If it works, then it would be nice to  get
max coolant flow when you need it most (High power takeoff with low air flow
through radiators) and then save HP at lean cruise by lowering the flow rate
and associated losses.

    They certainly have been made to work in auto and marine applications.
While I must admit to some skepticism as to their suitability for aircraft
use, I am always ready to revise my opinion based on some real world data.
So good luck and let us know what you find.

Best Regards

Ed Anderson
