OK Flame guys…
Have you ever run a set of stock Bravo Ones and were just a little low on RPM (lets say 250 rpm) then have them labbed?
If so what gains and losses did you experience if any. It seems the always lose cruise speed at ~3500 rpm. Is this true of this situation? What about on top?
Any info would be appreciated.
Thanks,
Dave

No Flame owners have had there props labbed????

Dave,
Labbing a prop usually adds slip. At 3500 RPM slip is worse with a lab prop in my opinion.

I talked to Ron Steiner @ Mercury, He tells me the labbed prop comes with .060 cup in the prop on normal labbed conditions. When they lab it up one pitch they increase the cup to .080. That really does not add pitch in my opinion, just reduces slip. My new 33P are 32's with .080 cup. It hooks up muck better than my labbed 30's. I plan on sending my labbed 30's back to get them cupped up.

My boat with 500's, 30's labbed, had 12% slip. 5300RPM @88 MPH.

Thanks Linnie,
So just thinking out loud here, if I wanted to gain 100-150 rpm and some speed out of my 26s and had a shop that actually re-pitches rather than adds/removes cup when labbing a prop do the work, I could have them re-pitch to 27 and lab them. Assuming that labbing increases ~300 rpm, I could "theoretically" have my 26s repitched to 27s and labbed, gain my 150 rpm, gain some speed and possibly retain my cruise efficiency by moving up in pitch. Sure sounds good on paper (or screen ).
What do you think?

I do not really care for how thin Mercury gets them. I agree removing some material helps but the last .020-.030 they remove just makes for a weak prop unless you are in race conditions. It does not take much to mess a full labbed prop up. I agree with adding some cup over the standard .060. Maybe .070 would be the right number. I'm not sure labbing adds 300 RPM. My buddy just got his 35 Flame with 30P stock bravos and I think he gets allmost 5300 out of them as well. He only seems to be running +-86.

Whats your slip factor? If over 14% I would add a little cup. You will loose RPM though. Adding pitch will loose RPM. Maybe just labbing would be the first pick.

Keep us informed.
