Sounds like you may be leaking from the exhaust cooling cavity outside your exhaust ports or maybe the head cooling cover passage ways clogged up. Are you sure your water pipe is connected to the bottom of the powerhead? Those are a few places I would look for clogging or not connected when the powerhead was mounted again. I have the same motor & the pump outputs plenty of water for cooling at all times.
Just a few suggestions to check out.
Good Luck & if you stopped it fast it should not have damage hopefully,
