So you have 9 lbs of honey available to you, and 3 lbs have dumped into 3/4 gal water? I would take the honey water, the rest of the honey, dump them all in a fermenter, top it off to 3 gal total volume, pitch yeast, add nutrients and go for it. If it's hot enough to scald you, chances are it's fine with anything that's on the bottles. The new yeast will tend to outcompete other bugs anyway. It may not be what you wanted to do, but just plow ahead now.
