What are you guys running for props (28's)
 

I have been doing some prop testing, just kind of curious what everyone else is running and how they like what they have. Or if anyone has played around with some different stuff and what the results were.

running 30 pitch bravo/4 blades.
i have played with 3 blade vs 4 blades on other boats, not this one but i always thought the 4 blade was a better all around prop... just my .02

Still running three blades they blow out all the time, found that to be the case on the single 28's as well. four blades way better.

I just tested a set of 4 blades, lost almost 5mph top end and they porpise worse than the 3 blades. Much better out of the hole though, snappier mid range. Cruise speed at same RPM was just about equivalent. I think they have less bow lift than the 3 blades, so it takes even more speed to carry the bow while trimmed out without going into porpise mode. Pretty sure I am going to send my 3 blades out for labbing and adding some cup to carry the bow a little better. The 4 blades with labbing to the hull would probably be good all around and a touch slower, but I am not going to spend that kind of money just to try it.

I'd ask him his opinion about Rev 4's, if they make one large enough for your application.

He said they are worth a try but didnt have a set of test props in the right size.

I've been running labbed 23 since I got the boat. Of course mine is single, and not much for power. I've been thinking about a 24 for a little more bite.

Steve I run a 24 4 blade...never played with anything else on it. Get pretty good results I spent $200 this last winter and had it tuned which did nothing for me but make it look a bit better when it's on the trailer.

guys a rev4 by merc works great on deep drives with straight bottoms, call or email Brett at bblades he has a program so you can test props. cwc who did you use:eek:, thats not right.

steve im running a 24 labbed on mine and doing 73 on the limiter we can hook up and give it a try on your boat before you purchase one. cwc you might of had someone work on it that didnt know how to do it right. i had my normal prop guy (for the cheap stuff) check the pitch on a prop, he tweeked it and polished to a mirror finish absolutly beautiful but i lost 6 mph he polished the cup out of it. send it to another place I would recomend bblades or dans prop shop

Just got my Mirage's back from BBlades, they look real nice, hope they work as good as they look. Labbed and a little "tweaking", will see what it does. They worked real well for me in stock form, just hoping for a few more RPMS and a little more bow lift. Its a real pisser having to wait until spring to find out the results. I am still interested in getting a set of 4 blades that work good for cruising speed. Anyone tried Hydromotives yet? Brett thinks he can make me happy with a set of Bravo's but they would have to be heavily modified. Cant speak on the results yet but I learned a lot through talking with him, very informative when it comes to props and how they work.

So three blades will carry the bow better than 4 blades?

Dale, think about dragging the pantera up to next years saber rally!

A standard lab job should get you 250-300 RPMs, I'm sure more could be had if you wanted. I am curious to see your results.

Chris how is it going? No probably not, that date you guys are talking about I think we will be at Cumberland.

Dale, Lesley and i plan on going to Kelleys and PIB a few times this year.. hope to catch up with you at some point

He was shooting for 150-200. I dont think they were cut down at all, just trued up and a touch of cup added, plus some minor geometry tweaks. Supposed to add a little more bow lift so I wont have to trim as far for equal results and carry the bow a touch better at cruise so I am able to trim out more without starting to porpise. I hope it was worth the money, if I can gain a couple MPH its by far the cheapest way to get it.

I was told my 3 blades provide more bow lift than the Bravo's I tested. He said based on my results the hull doesnt like the stern lift that a Bravo makes. Also had an interesting talk about propshaft depth and shorties. I guess one of the negatives to shorties is less bow lift. Was going to find a set to try but maybe not now.

Yes, a little but would think some extra cup could negate that or even add a touch more bow lift. I had found that with the addition of the box and raised prop shaft height speed remained about the same but slip went way up. I haven't had much of a chance to mess with variables yet or a labbed prop which I think will help tremendously.

Makes sense and follows pretty much what I have been told. Props go up, slip generally goes up somewhat. Thats why guys with real high x's run 5 and 6 blade props. The way Brett explained bow lift in relation to depth is that when a blade is on top rotationally it generates downward force on the shaft, pushing the bow up. Makes sense to my limited physics. Less water over the blade means less "meat" for it to push against and thus less force can be applied downward.

My situation is a bit different, my slip numbers are excellent, 6-7%, and I was hesitant to mess with that. Really all I was looking to do was pick up the couple hundred rpms I was short of redline and hopefully a couple mph with it. That and to be able to trim out and loosen the boat up a little more at cruise without creating a porpise to get best speed there.

If you havent already, I would reccomend calling a prop guy and asking questions. Brett was really informative and helpfull. He spend a lot of time answering my questions and explaining the mechanics behind what they were going to do and the reasons for it. I will reserve final judgement until I see the results but very happy with them so far. Have also heard good things about a couple other lab guys, only used BBlades do to good words on here and being close for shipping.

I would think in your case the right prop would help a lot, especially if your slip numbers are really high.

34p 17 1/2 6 blades about 5800 rpm :evilb::drink:

Smart azz.... :lolhit:

I wish I could turn those wheels :)

BTW, you have any preference for dates on the Rally? We are thinking weekend of July 21

Hey Eric, the 21st works for me. Is something going to happen in Saginaw the week after?

I have a 24 three blade, hydromovtive turbo for sale. running 30 and 32 5 blades one hydro px5 and other herring..

Yes, there is a Poker Run here that weekend. I dont have a ton on info yet, they are still finalizing some stuff last I heard, but it is July 28th for sure. Sounds like some of the other Saber guys are coming, you should try to make it. If there is a group coming I can line up dockage either at the run site or downtown.

Hmmm those look like the same ones in my avatar:bunnydance:

<<<<<<<<<<<<

Yes sir Jeremy, the same ones. I ran Cougarmans props up until Hardy. I think everyones stuff is back where it started! Oh, except for a couple of blades off the Fountain props and one whole six blade Herring off the Fountain....Those are in the bottom of the lake.

"and one whole six blade Herring off the Fountain....Those are in the bottom of the lake."

Ouch !! as if loosing a blade or two isn't enuff to foul the day up, but man an entire six blade Herring..:eekdrop:

That had to make you wanna chum the lake !!

we had that happen one year in gerrys 46 turbine skater, we backed up from a card boat. poof prop came off 5 blade herring in 8 to 41 ft of water, depending on tide. but it was providence RI harbor:eekdrop:. you can't see a foot in front of you, under water. we had a diver look for it, but the mud was so deep. he thought it sunk under it. we tryed a metal detector with no luck. play time two months.:cartman:

Kind of chasing my tail on the Fountain. Directions as follows- Throw a blade, replace a prop, then break a prop shaft. Replace prop shaft and prop. Repeat as required.

30's? Wow. What kind of power are you running?

Chris' boat got lots a power..

Out of curiosity what are you turning that engine ? I assume that's through a 1.5 ratio ?

oops it was 8 to 14 ft water not 41:poopoo:, on my boat been thinking of trying a p5 trans lifting prop.

Artie, while in Miami, I spoke with several very experienced riggers concerning your boat. They all stated, you've got to remove the hook in the hull.

nono no its rocker hahaha. thanks buddy. yeh that looks like my next stop. factory has been no help with cg either, so I am going to skip that. no reaon to find mine, when the guys who built it never took or adjusted theres. anyone know if this is a copyed hull , splashed hull. if so maybe I can find the cg from them. Kurt did you mean rocker. I do have a guy who will give me a price on that. it should be about 4ft to 6ft of rocker thats from the factory. should bought that 05 sutphen.

....aahhh, yeah ROCKER! -Been on the road too long. They all said it will never run right with rocker and the weight.

oh with the hp I have a bravo is not the ansewer:lolhit:, KONRAD BABY its bigger, meaner, and shorter. if the guy with the 31 sutphen didn't recut for twins, I would of paid the 14 gs and stripped the saber of its power and sold it. I know its bottoms are straight, no hook no rocker, no pads, not even a step. but boy that new OUTERLIMITS 29 running 97 with a 525 and 4 or 5 steps is BAD AZZ. hope to run that with twice the hp:cartman:. later

It's not running a 525. its a 600SC.

they were going to use a friends 525 for testing, was the talk a while ago. it was boxers spare motor. 600hp not dialed in yet 97 sweet. since boxer is putting custom power back in his old/ new 26 sutphen. the 31 he has runs 92 to 94 with 950hp. so if the bottom gets done I should be around a 100. my drive height at , propshaft worked great at 3''/4'' and 5'' got on plane easy with the 4 and 5 blades. if I only had a extra 100,000 kicking around I could of bought a 29 ol. boy 1100hp in one of them wow.
