does anyone have a good approximate way of converting flow to thrust? as an

Thanks,

Hmmm.. Let's do a VERY Quick&Dirty approximation. 5 Amps at 12V = 60
Watts times 2 pumps =
120 Watts. 746 Watts per Horsepower. So About 120 / 746 = .16
horsepower. Assuming there are no losses (!) how fast will that move
your boat??

(Major mechanical / hydraulic issues that I can't figure out
remain).....
