The propeller on your boat has a big impact on the performance of your boat. This is the place to discuss this subject.

Testing out some props tomorrow

Postby K-Dubb » Fri Jul 20, 2012 7:27 pm

I will be testing a mirage plus 23p and a mirage plus 25p labbed tomorrow! Currently running a vengence 23p. Doing the testing program from bblades.

Can I use the hub kit I have on both of these props?

Any other gotchas? I'll let everyone know the results.

Yes you can use the same hub kit.
It should be the flo torq II part#835257Q1

I have a Mirage Plus 25p that is labbed and cupped, and I really like it...

Are both props labbed, or just the 25p?

Just the 25p.

What is the torque rating on the prop nut?

FYI: The MAX. rpm (WOT) for the 496MAG is 4400-4800; the 496HO is 4600-5000 at normal operating temperature which is 160 degress.

Per the Bravo 1 service manual, it's a minimum of 55lb-ft depending on if the flats of the prop nut lines up with your tabbed washer.

If you are at 55lb-ft and the flats on the prop nut don't line up with the tabs on the washer, tighen the nut until they do, do not loosen it....

Thanks! I am at about 4950-5000 in 100* heat now.

I think you will like the 25p.
That is what I have, and my PRM's are around 4700...

i run avout 4900 RPM with a 25p ballistic. my 25P mirage gets me about 4850 RPM before she starts to air out. i'm interested to see what the labbed 25 does for you. what was it labbed for, top speed?

I am not sure what it was labbed for. Bblades just said another guy backed out on it.

Well I am not really happy with the speeds. I don't know if you guys are running in cooler weather or what.

DA was about 2500 *edit*, so not that great

Light chop.

I turned the 23 mirage at about 4850, which got me 61.
I turned the labbed 25p at about 4500ish, which got me 63.4

This is using the gps app on the iPhone. Not sure how accurate it is.

2 people, 2/3 gas.

I am not sure how you guys are running the speeds you do.

DA for my area is generally between 650 to 800. you can also look for your best numbers in the morning, and when humidity is low. if you have a bowrider, put the bow cover on. i'm still waiting for that perfect test day when i don't have the whole family & lots of gas.

No bow cover. This was done at about 9:30, but DA was still 2500.

Sending the 25 labbed back to bblades. They are going to adjust the rake a little and send it back.

Yes, you should be in the mid-upper 60's

Hit 64.4 today with the labbed 25. DA was 3200 so I would say that is pretty dang good!
