lab finishing or blueprinting consists of reducing blade mass (thinning out the blades ,making sure all blds are in correct pitch,size and shape with a precision perfect balance and adding modifications toTHE CUSTOMERS REQUEST.THERE ARE SEVERAL TYPES OF LABBING A PROPELLER AND ONE IS WHAT WE CALL (RSTSF) RACING SUPER THIN SATIN FINISH, AND THE MOST POPULAR (OPMPF) OFFSHORE PERFORMANCE MODERATE POLISHED FINISH,retaining durability with a beautiful apperance and the (MSF) MODERATE SATIN FINISHED PROP RETAING DURABILITY BUT WITH A BRUSHED LOOKING FINISH,ALL LAB JOBS WILL GET YOU ADDITIONAL PERFORMANCE OUT OF YOUR PROPELLER/LET Darin know if we can meet your needs today. we have had several questions about diffrent types of labbing, hope this helps explain a little about our process of CUSTOM LABBING YOUR PROPELLER.

Hi Darin,

Try to explain a little more the main differences between the different labbing methods and put on rank by some parameters (let's say, prop reliability - what makes the prop weaker, prop slip perc, more speedier, more plane - aware, and cost).

Yeah, I know that I requested for much info but prop labbing seems a quite interesting method of gaining performance or fine tuning our boats.

Thanks.

thinning the blades,the thinner it is the less energy it takes to move it thru the water, creating greater speed ,thinning the blade makes it weaker or a nick or small burr on the leading edge will and can cause a stress crack,that why its important to have a perfect prop when running high rpm, and being perfectly balanced as most (massed produced props) are not. I cant and wont give my trade secrets over the past twenty- five years of repairing propellers hope I have helped some but this is why we offer several options to meet your needs.

Can props be balanced and blueprinted, but not labbed? I'm asking because I have a Blackhawk Drive with hard to find props. I don't want to weaken them by thinning the blades, but I want to have them balanced and blueprinted. How are they balanced, is material removed from the back of the blade?

yes to balance the prop material has to be removed from the back side of the blade normally it does not effect the thickness hardly at all to get the prop balanced,but as I mentioned there are diffrent thickness options ,ITS UP TO YOU ON WHAT YOU WANT,ALSO LET ME KNOW/THANK'S

Darin-Most labbing takes away 12% of blade strength when thinned to 1/2 of original thickness.

What would you charge to Balance, Blue print, and lab a 14x19 stainless for each of the methods you posted earlier?

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??

What kind of discount does the moderator get on labbing

195.00 plus 15.oo shipping back to you/let me know Darin
