But the water would be able to fill and be ejected from the pump quicker
through a larger opening.  Greater flow due to more strokes per unit
time rather than more volume per stroke.  Still, these pumps are
designed for 11' of suction head, so the 6-12" head from bottom of bilge
to outlet hole is insignificant, whichever pump you choose.

In terms of "ejection" though, I'd bet you can spray water farther from
the 1" opening and be able to more effectively douse your paddling
companions!
