Very, very manly, I'd say. (I even caught myself thinking along those
lines at a [ gasp! ] Harbor Freight store where they were showing a
semi-trash pump that looked pretty mean) :-)

Brian Whatcott Altus OK

How about upwards of 900 gpm (yes I do mean over 50000 gph)?

Its engine driven and clamps round your prop shaft, acting as a bilge
blower (or rather sucker) untill the water gets up to its intake :-)

Oh yes! Reminds me of that scrap yard builders series on TV:
the objective was to build a fire boat capable of dousing a flaming
building on the far side of a lake.
One team decided to use water jet propulsion as well as for dousing
the flames. They started with a brake drum, and welded on three vanes
for the impeller, and cased it to a hose.
Centrifugal impellors can take plenty of abuse, and absorb lots of
power.
