 50 amps at 115 Volts 7.7 HP Impressive :-) 115 volts at 25 amps 3.85 HP

also

 impressive. You want to try a 7 inch pulley?

The 50 amps, of course is the "in-rush" current, so I wouldn't put too much
stock in that number, however the 25 amps at 115 Volts was where it was
steadying out, so I feel comfortable saying that it was drawing a hefty power
~3.8 HP at that time.

I'll pass on the 7" pulley, I think we have enough data now.  It is a *real*
pain to set this up, because I just installed my wings on the fuselage to put
on the fairings from fuselage to wing, and to establish the correct wing
incidence.  My hanger is a little full right now.

OK Bill. Many thanks for all the testing. This has greatly increased
our knowledge on the stock pump. Since you showed the way perhaps 
someone else will do some further testing on stock type water rads.
