Prop Help

Going to buy a spare for my 2021 Z19 Pro. Factory prop is a 23P Fury. Max RPM 6000. Unless you are perfectly trimmed, steering is very hard on left turns. A 24 Bravo has been suggested, looking for more input! Any help?

Thanks in advance!

Have checked the cavitation plate torque tab?
You don’t want to run 6K rpms very long, 5800 is a better target, what engine & hp?

TNX for your reply. You have a PM
The motor is the V8 Pro XS 200HP. There is no torque tab. Max RPM is 6200. I am sure with the right conditions I would turn 6200.
I am not interested in max speed, looking for something that will give best handling.

I don’t see the PM?
Torque can be an issue of too much wetted hull. To add prop lift you need negative rake, to add speed you add prop tip cup. Changing pitch is a new prop. A good prop shop can modify your the prop before buying a new one.

Years ago I had my Bass Renegade four blade stainless prop on my TR19 Triton worked down from a 25 to a 23 pitch and it's the best money I ever spent. My understanding is two levels of pitch up or down is the absolute max without having to buy a new prop. This got rid of chine walk and made my boat more responsive with a better hole shot, which works perfectly for me on the Delta. I only gave up a couple MPH on the top end with my 175HP Ficht.

Phils Prop Shop or David at Russo's are great local prop guys who can talk you through it and suggest what needs to happen.
