Hmmm. Are you running it in this hot weather?? How is the powerhead temp?
Generally speaking, the water discharge on these engines never gets “hot”.

PS: I’m guessing you are referring to the overboard indicator water discharge on the Merc. If so, this outlet is often tapped out of the begginning of the cooling circuit, so it is usually relatively cool…

Keep in mind there is a tiny bleed/exit hole under the powerhead that leads directly from the lower cylinder cooling sleeve into the exhaust housing… This hole is there to help keep the exhaust housing cool. Be sure to check this, could be carboned up. Don’t reinstall the powerhead without being 100 percent sure this hole is clear. Post pictures if that will help

As Don said above, pull your powerhead again, and look for the tiny bleed hole under it.
I had the exact same problem a few years ago on a motor I was restoring. I followed Dons advice and that was the solution.
Get a sharp object, I used a dental pick. Flip your head upside down, and pry all around. My bleed hole was invisible from years of carbon buildup from the old 30 weight oil/ gas mixture.Bob D
