It is possible the WP is bad, but generally they will fail at the seal/bearing and coolant will come out a "weep" hole cast into the pump.
Some pumps have a plastic impeller and these can seperate from the shaft internally causing reduced water flow.
NEVER drive a Honda if it has overheated, shut it off quickly.
Aluminum is very sensitive to heat and can warp if overheated.
