Looks like somebody is dreaming in Technicolor. I sell DC pumps on my  
web site. The smallest 3 GPM pump is using 5-7A and the pump is 3  
pounds. Pump that will pump 15 GPM at 12V DC is about 30 pounds and  
huge motor. There is no free lunch. Pumping 35-37 GPM on 5-7 amps? My  
transponder needs 7 amps.
