Hang on George there is a lot more on this as soon as Bill sends me the
complete pdf on the whole paper. The stock water pump pumps up to 50 gal

per minute

as I recall and consumes 3 HP. If you are thinking of an electric pump
that would be 172 amps at 13 volts at 100% efficiency. If the electric

motor

was 80% efficient that would be 215 amps!

Paul,
No electric water pump for me matey - you have warned me/us of that too many
times already.

As you know I'm looking at the 12A and it has a heavy cast iron water pump
( 26lbs) so I figure a  water pump off something else might do the job (
similar to what Don Dunbar did) and position it somewhere down lower. The
water pump off my Landcruiser 4.2 litre is only 11 lbs but I don't know if
it will take the speed, but I can slow it down if necessary.

 The  figures Bill has done will help in the selection of what's required. I
figure I will have to test different pumps and compare them to the Mazda
pump (as Don Dunbar did), but these calculations might short cut that
selection for me.

I will wait, as you suggest! 50 gal/min seems more reasonable, I'm not
understanding something.
George
