What size prop is recommended for the new v8 250 on bass boats. I see the ones at pro choice have 23 fury's on them.

Interested as in this as well! I would think they could utilize a smaller prop given the higher red line. Better hole shot AND still get good top end because the motor spins higher.
It will differ depending on the boat, The Z521L Rangers are being shipped with a 23p Fury 3. Thing heavy 21 foot boat. Lighter hubs will have a taller pitch.

I'd say count on dropping at least a pitch from what the 2 stroke ran on the same hull. Could be alot of people finding a bravo is quicker than a fury as well
Looks like with all this supposed extra torque the 4 stroke would swing a larger prop
My new Nitro Z21 came in with a 23 fury from the factory. Going pick it up Saturday and test run.
I think it will be a 24/25 in the end, but they have tested them and 23 is a overall pitch. I think it the timing curve and the 23 allows for instant holeshot and timing curve allows the midrange and WOT with RPM band. boats got power and with a 1:75 gear its allowing the gear case turn a 23/24 easier without over revs. my 250 Verado Pro turns 6250 WOT on a 26 Bravo FS (Croxton B&B)1:85 gearing, so I feel its the case gearing and whole layout on this V8.

We also need to remember that for models running the G2-TM gearcase, that case ALONE will account for a decrease in pitch of approximately 1 pitch point (due to substantially lower prop pitch numbers).
23-24P is definitely a realistic choice on heavier hulls.

Thanks for the suggestions. I'm gonna repower my Z-9 with one and just trying to get an idea. The 23 fury's are back ordered till 23rd of June. Maybe I can find a 24 pitch. Wonder how a 4 blade fury would do.
Should do very well.

I think this is to get the RPMs above 6k. A 23p is just as fast as a 24p if u can turn it 200+ more RPMs.

I am in the process of repowering my Triton TR20X with a 225 Pro XS four stroke. I was wondering what prop to use. I want a Fury 4. I have a 25p Fury 3. My motor won’t be in for a couple weeks.

Prior to the G2-TM, prop slip numbers "below 8.0" were pretty rare. I've seen well documented cases MANY times with prop slip in the 6's (with previous gearcases, that would not even be believable).
Lower slip numbers mean higher load (due to higher efficiency). Hence a lower pitch of 1 point is usually necessary JUST due to the G2-TM case geometry.

Good info there on the G2-TM case !!! I just calculated my 2018 Eyra to be 3.87% slip ! 2 people/half load of fuel/ full of gear, 79.5gps mph (both directions) with 26p Fury 3 @5880rpm. Engine is a July 2017 mfg date ProXS 250 w/Smartcraft gauges, w/1.75 gearcase. At 5880rpm/1.75 ratio and 26p prop the 'theoretical' speed with 0 slip is 82.7mph. So, 1.0-(actual speed of 79.5/theoretical speed of 82.7= .0387 or 3.87% slip !!!!
