I want to try "faster" prop on my Suzuki outboard

[Bataperri]

Hi.
Im thinking about props on my 2008 f140 suzuki motor.
I want to try to get him a bit faster, its on a zodiac srmn600 thats also 2008 model. I have aluminium 14x23 prop and its goin very easaly to 6000-61000rpm and the speed is about 40knots.

Would you guys recommend same diameter and more pitch or ? And would you stick to aluminium og go to SS ?

Looking forward to "hear" your opinions

Is the 6000-6100 rpm Wide Open Throttle with your usual load on the boat?
Will the engine rev any higher?
This shows the recommended WOT for your engine to be in the range 5600-6200: https://www.rubexprops.com/boat-prop...e/?make=Suzuki

Yes, its wide open throttle... No it wont go higher, but it goes really fast to this RPM.

Higher pitch, if you're going for a Suzuki prop generally as the pitch gets higher the diameter decreases
