Re: QD19 running a little hot?

I wouldn’t run those kind of engines on a flush attachment. They don’t work very well. It’s best to use a barrel and fill the water up to about three inches below the transom clamps. As the other two guys have stated. plugs won’t have any bearing on operating temperatures. Performance will have a small change though. J6C’s or J6J’s are the best thing to run in that.
