RH, 1- what is your combo? stock mill, impeller cut...etc.2-weeds ,well you got me on that ,dont usually have a problem with those up here!3-engine temp should be minimum 160,with 180-190 prefered.4-if you have a gps use it ,they help quite a bit, so does the tach.do you have a trim gauge?speeds up return to the sweet spot,this again depends on boat weight(empty/full)(passengers..etc.5-I find spray 9 works the best for me.Anyways Im sure that there are some various other ideas out there,but gives you a place to start!! Roosters away!!!
