What prop on a phantom 16

What pitch props do people run on phantom 16s .This boat has a merc 135 on it and is running a 23" lazer reving out at 5200. Engine should go to about 5600. i know proping down would get the revs up but a 20"/21" seeems small to me. the owner wants more top end.
cheers dan

Prop

Depends on engine height !! but try a small hub 24" laser !! the smaller dia will get the revs up & should increase the speed

I used to run a 23 Yamaha Thru Hub Competition prop on my offshore 1.3L P16.

I also had a 25 Over hub cleaver but found that very torquey.
