2016 2 + 2 Prop recommendations?

[twsykes]

Hey guys,
I have a new to me 2016 2 + 2 and it is running a 30P prop with a diffuser on a 250 ProXS. Sees to run pretty well but seem like it might not be the right prop. What do you guys recommend?

I ran a 30 Promax and a 32 Promax with 4 open holes and no diffuser on my 2+2 250 Sport with 1.75 gears. I always run a loaded boat and love these prop combos. 30 was for summer and passenger runs and 32 was solo later fall/winter/spring runs.
