Re: QD19 running a little hot?

[Don]

How warm/hot was it out when you ran the engine? These engines can appear to get pretty hot when outdoor temps warm up in the summer. I’m assuming you have the impeller housing/driveshaft tube/orings in place.
I know guys have mentioned that there are little drain hole(s) inside the exhaust housing that provide an exhaust reiief into the water outlet hole. Sometimes these relief holes get plugged with carbon. Perhaps these relief holes allow a little extra water down into the exhaust housing to keep it cool as well. I admit that I have never really taken the time to notice these relief holes, but be sure to investigate if you remove the powerhead.
