You probably have or had an impeller lose a fin or two and they are trapped in the cooling coils not letting enough water thru them to cool the engine. Pull the end cap off and check for debris. Use a thin rod to clear them. Pretty easy fix. If it is your impeller, just change it out... Especially if its been a couple of years since your last change. They last about two years on average use (100 hrs/yr)...

I pulled the inlet hoses off of the exhaust risers. I can blow air through the left side, but I can not through the right. I believe that one of the risers is clogged, \rusted.
