is it smoke or steam and from where is it coming? Checked connections on exhaust system? Do you have any riser leaks?

Have you recently changed out your Prop, I tried changing Prop pitch to get a better hole shot but.. at slow speeds it gave off an annoying whistle. Could also be a bent prop

prop is mint....
