prop for Phantom 21ft 200hp

Hi all!

I'm running a Tempest Plus 14 1/2" 25P fairly good. PVS caps fully closed. Pics give an idea of my setup.
As there are many P21's out here : what props do you guys run ??? I just lack this basic information.

My goal is to improve a bit on acceleration and try to keep the good top end while reducing the chinewalk above 100kmh. Maybe also a bit more bow lift as you can see in my youtube film
I'm currently testing with lowering engine height, but maybe testing another prop is the better way to go....
I think a chopper style prop 26 pitch could work for me.
If so, what should I go for : Mazco, Chopper II, Lightning E.T., Triton, Yamaha Drag, other ?? I'm also looking for more info on what exactly small-ear and big-ear chopper are.

Thanks !
T.

And probably low water pickup then you can get the engine higher

@grandmas denture : Thanks ! still it feels there's room for improvement. I think my engine runs strong horses.

@scooby_hugh : you're right, but no low water pick up for now for me. Now I come to think of it : can you even run a chopper style prop without low water pickup ? ... I guess you can as long as you don't compromise the cooling.
Why would you use a cleaver on a P21 that normally needs bowlift ? In rough waters maybe ?? to keep the nose down and the stern up ??

Anyone else want to share propinfo ?

Thanks!! T.

+1!

That 200 must be much more than that if you're expecting more speed!
