Which 4 blade prop for 20' ma

[Seacraftma]

Hey there I know there is a lot of info about props on here for the 20' boats running a 3 blade, but I can't find out what size 4 blade to try. I have a '02 master angler with a T-top which I just repowered with a new df140 and I'm currently am running a 14x20 three blade SS Suzuki prop. With 70 gal. Of fuel and 2 people I'm running 37, 38 mph at 6000 rpm. I would like to try a 4 blade for a little more stern lift so if anyone is running my similar set up with one I would like to know what performance numbers they're seeing and what diameter and pitch. Thanks
