Dave, that is the point of the electric drive. The engine driven pump is
wasting a lot of power because it has to bypass oil because of it's fixed
displacement. So while it draws 3 hp (I think more but don't know for sure)
during the high speed run. maybe 2 hp of that three wasted in bypassed oil.
I think ytoiu would need a 1 hp one...

Now I still wouldn't use an electric one...
