Have a new 32 Glasstream CC with 275 Verados. Boat has the new double step hull.
Running 4Blade Bravos with 24 Pitch. Hitting anywhere from 6250-6400 RPM depending on load.Depending on load speed is 64-68 1/2 mph.
It appears on somedays the speed only increases about 2 mph between 5500 and 6400 rpm.
Any tricks for these props for speed and what about type of 3 blades?
Boat and engines are at 6800# and then 1308 in fuel for a gross weight of 8108#.

Your slip is varying between 15-18%. A little high. Increases as the rpm comes up.

Yes there are many things that can be done to the props. First you need to make sure other things are in order.

How deep are the engines? How are you rotating them, in or out?

Ok...the drives are turning out...the prop shafts are about 4" above the keel.
Mercury suggested pitching the 24's to 25 pitch.
Any opinions?
I saw where a triple Fountain fish boat had 26 Lab finish and [email protected]@5000..73-75@6250rpm
If I pitched to 25 then labbed or would the 26 Lab be an option?
Any ideas bbladesprops or throttleup?

Your motors are mounted pretty high. I would explore this prior to any prop work, props are always last. I think dropping the motors down may decrease your slip.

Agreed. Are you sure the prop shaft center line is indeed 4" above the lowest part of the hull?

After re-measuring..with out drives of the "in stops" so that they are almost perfectly verticle they shafts appear to be in line with a point relative to the drain plug or or between 2-2 1/2 in. up from very bottom of keel.

Still seem to be a little high. Is that where Glasstream suggests to set them?

Glasstream is very proud of where their X-deminsion is at on all their boats
After reading all the other topics in this section and hearing about Mercury stated pitches not really being as stated( 24's are 22-23*) ..I'm figuring this may be where the problem is..and like I mentioned before of pitching up then labbing could that put us where we need to be?

Also we seem to be learning how to dock all over again compared to all of our experience with IB/OBs.
These Verados are closer together..so not as responsive or not enough P-Factor..orif they are mounted too high i guess that would make docking more difficult? Not enough bite in the water..enough prop in water.
They act like IB/OB that are turning inward.

The closeness is what I figured and said above but I also figured a high-X would also limit it.
Getting ready to go play with it some more
