08 PS197 w/MCX and Slot..which Prop?

I have the 2008 PS197 with the MCX and Slot and the boat came with a 3 blade prop from the factory. While the boat does not lack power, I noticed it is running 4020RPM's when dialing in to 34mph on PerfectPass, which seems a bit high.
So, I am wondering what others are running with the same configuration? Maybe I got the wrong prop somehow.

Thanks in advance.

IIRC, my 05 197TT with MCX and the 1.26:1 slot and a 4 blade 13.7x15.5 runs ~3400 rpm at 34 mph. 4800 rpm at WOT.

The prop that I ran on the 1.26:1 tranny with the MCX was the Acme 3 blade 13.25x15. It is the perfect match for that boat.

My '08 214 has the same engine/ tranny with the 3 blade prop. And 36 is over 4000 rpm. The rev limiter cuts off at 5400 rpm, IIRC.
Prior boats - (3) X14's, (3) Prostars, and a Tristar.
