Pardon my ignorance, as I am new 292 owner, 08 w/6.2's, I have a lot of slip out of the hole. Could someone define "labbed" props? Thanks.

A little up from neutral for top speed. Water conditions and boat load will dictate the ideal trim setting. I will accelerate with trim neutral and once over 60 mph or so start bumping it up a tad while watching the gps. It will slowly climb to 70 mph and if you over trim it will be quickly noticed by the drop in speed on the gps.

Labbed means careful balancing and thinning the blades in effort to increase high speed performance. In general you can lose midrange cruise efficiency if the lab job is only focused on increasing top speed.

Last year I finally hit something and dinged one of my labbed props enough to require rework. I sent both to BBlades and had a long talk with Brett on what I was looking for. There is a trade off between top speed and cruise efficiency. I told him I wanted a balance off both. He did a great job. I have the same top speed as the Mercury lab job but better cruise efficiency and planing. He added a little cup to the blade tips which he said will hold the water better and help efficiency but this does not help top speed and can hurt that slightly. Remember, it's a balance...

They are also much better balanced and run so smooth with less vibration that I thought was simply normal with the original set.

Prop work is an art and Brett really knows what he is doing.

Thanks for the education, I will give Brett a call Monday.

Anyone ever run a straight up stock Bravo 28p? Thinking of getting a set and then sending the labbed props to blades for fine tuning. Simply want to know what to expect with the stock 28p. Any advice would be great.

I ran stock 28p for 5 seasons on my 292, I have 350 mags and best I saw was 70.3. on GPS but was a solid 68mph boat everyday all day. Getting on plane was an art form for me with the 28s, trim down tabs down and had to ease into the throttles just right in order for them not to slip and bite immediately. I got a set of 26p bravo's just to test with and first test run with them I just hit the throttles and it came up right out of the hole with no hesitation and bit immediately. I still have the 28s with hubs, PM me if interested.

What did this do to your top end?

I lost about 1-2 mph I believe. Maybe 1mph in my mid-range, its definitely not noticeable. I don't really know. I'm definitely not one to beat on my boat, and its so rare that we get the perfect conditions to do any accurate testing. It's either a lot of boat traffic or its blowing 15-20 it seems. I did have her up to 66mph last season, but only once for a few seconds. That was with 4 adults 3/4 tank and fully loaded. So I'm assuming perfect conditions 2 people loaded light with light fuel I'm sure I could hit 67-68 if I really wanted to. Still have never hit rev limiter.

I run box stock 28's on 6.2's at 5k and a best of 72 but everyday 69/70 hot days and a heavy load it will turn 4900. just had cutting edge labb and add some pitch they should be a 29.5 pitch. will let you know the results when she goes back in the water next week. hoping for a everyday of 72 and perfect conditions 74+

I just got my 2009 Formula 292 with 6.2's, it has the 28 pitch Bravo 1's, I've noticed that the props start blowing out right at the point where the bow starts to come down and then they hook up. I read on here where someone else with that problem went to 26 pitch props and their happy now. I'm debating do I get my props labbed or just buy 26 pitch props? Opinions?
