strength

HyperBaja,
I think that you got that wrong. After labbing, the blades RETAIN only 12% of their original strength.

How about it Darin, is this correct??

I dont know about percentages but the prop will not be as strong as it was originally.:D

I think it's on the web site of one of the other "Prop people" ;) here on OSO that removing 50% of the blade only reduces the strength by 12%.

What kind of discount does the moderator get on labbing
we charge double:D :D not really,it the same as everyone else plus additional 25 percent off,so the cost is146.25 plus shipping of 15.00 .:eek:

that's generous Darin, I appreciate it, I wonder what I can do? 1999 Baja 25 outlaw 502 mag, headers, ecu, K&N, 68 on GPS at 5,000 rpm occasionaly bumping the limiter, what rpm could I get pitching it out to a 25 and labbing and what possible increase in speed?

HOUSTONPROP 01-11-2003 06:24 PM

Pitch to a 24 pitch, add cupping, thin out moderalety, rebalance to perfection and satin finish. You should pickup 2 to 3 mph if the prop is polished, after the mods, it will probably run 69.5 to 70 mph, just my opinion. Also if we polish the prop there will be a small fee of 40.00 extra. your right winter sucks and its cold in Houston tonight./Darin

there are several factors involved and one, is who does it And how Hot do they get it. And do they let it cool properly,I have seen many props were the tensile strength of the prop is ruined because they dunk the prop in water to keep working on it.not sure how you can really figure this accurtaly.

Has anyone done this with a bravoIII... and with what results? '98 Formula 252LS 502MAG/BravoIII 28P's pulling 5150 rpms at WOT with a speedo indicated 68mph.

Thanks,

Thanks,

Mine's a BIII and labbing and adding cup to my 26's got a solid 2 MPH and smoothed it out. A more "performance" hull may have responded even better.

well since you sound like you know this stuff pretty well
I have a larson senza 25' stepped its the DDC hull
Im running a Stilleto 21 ss it has the vents on it
calculated slip 23-24% 350 mag alpha
3800 dry wt 4700 rpms 1.5r 49-50mph gps
its blows out if I try to trim it out, I mean I start trimming and the speed increases then suddenly I blow out and drop off plane.
Im hearing that a 4 blade would work better only because of this
hull is not a regular v-hull
