Trottle-Up's Barracuda Propeller
 

Throttle-Up Propellers has announced a new line of propellers with a radical new design that promises to become the standard for racing applications.

The new “Barracuda” propeller is a combination cleaver – round ear six blade with alternating blade type and diameters mounted on a can hub.

In back-to-back comparison testing, the Barracuda has produced 2 mph increases in top speeds over the conventional six-blade design.

The Barracuda was developed by Matt Croce and his Throttle-Up staff to give improved mid-range and top end performance. During testing, the propellers show that they act like two separate types of propeller at different speed ranges. At mid range engine speeds (3000-4000 rpm) the propeller acts like a mild mannered guppy improving ride comfort without the need for increased trim.

Throw the throttle forward and the Barracuda transforms from the mild mannered guppy to predator attack mode. As speed increases, the clever blades lift the stern of the boat reducing wetted surface and accompanying drag. With three blades working to carry the bow, and three blades lifting the stern, the result is higher top end speed, lower propeller “slip” numbers and better control.

This is one impressive propeller design…producing very impressive performance results.

Thank you Ken. I am very pleased with the results on your boat thus far....but we have got to get you out of the Rev. So we are going to build you a taller pitch. Lets see how much more speed we can get out of her! I would think 1.5-2 MPH at least! And lets not run additional weight this time, I really want to see what she does at weight....now that we know how she does heavy!

Julie

cool

Julie, 2000 388 slingshot, spinning in Ken Bowen's 15 1/2 x 32 five blade herrings off of his 38 zr donz. I think they were massaged by callabela. 5,500-5,600 netting 96-97 gps mph. Had to install diffusser rings on due to not being able to get boatb on plane.Would like a little more bow lift. Would these Barracuda's work.

Don't mean to interupt the conversation. We have done alot of 388's. Be carefull of big diameter multi blade props when the power gets int the 800's and the speed breaks triple digits. The boat can get very unstable and even dangerous without the correct X and propellers. The boat was designed to run in the 80-90 mph range. It will run big numbers but it takes some dialing. We have 2 in the upper 130's.

Oh yeah, Craig dosen't do propellers.

would these props work on a 42ex with stock 525's???

Hi Julie that prop looks sweet , it was mentioned at the fountains booth that your new cnced props ran as well if not better than herrings cant wait to get my 31 pitch barracudas please post any new stats

Yes, it's true Fountain has been doing testing with our props and they are the fastest props they have tested. Faster than Hering, by a little, and much faster than the best Maximus props they have ever tested.
They have been testing our regular 6 blade props, not the Barracuda props.
You should expect to see our props on other OEM boats as well.

It appears as if your drives are too high. Have you experimented with lowering the drives? The fact you couldn't get on plane without diffuser rings, you need more bow lift and your slip so high are all signs that the drives are mounted too high.

No, the Barracuda prop would make things worse for you with your current boat set up.

Matt

so are these the props I need????

We have not tried them on a boat like yours, yet. When the weather warms up you are welcome to test them. Or, if you happen to be in the neiborhood we can run them now.

Matt

The amount of stern lift these props can produce is amazing. We tried another setup...moving some weight around... and discovered that you can really load up the stern of the boat and still get some really good numbers with the Barracuda as compared to conventional props.

In real world applications, it looks like you will no longer need to worry about performance when your wife/girlfriend or buds come along with all that extra "stuff". You know, all those things that find their way to the back of the boat so you have drop the tabs or stand on your tippy toes to see over the bow.

This prop won't work for everybody...but if you need some stern lift....check them out!

It works quite well on Donzi 38 ZR's as well.

Just spoke with Julie today about their new prop for my application. Trying to find a few extra miles per hour over a stock Hydromotive.

Could you post what they have to say about these props on the 35 Fountain? Thanks.

We have run the CNC Props on the 35' Fountains and they outperformed our expectations. The attitude was great and the speeds were up all the way across the board!

Julie

Could you expand on this? Maybe some of the results you saw in testing?

Well, we saw 1-2 MPH increase over the leading speed prop on the market. It has been expressed that the propellers have a great feel to them...."very hooked up" "solid feeling".

Julie

Will these run on an outboard cat...and do you make an appropriate size?

Speed range...120-123

current = hubless three blade cleaver 15 x 34" pitch

T2x

You never know how this prop will perform on a particular boat til you try it. As far as size that's not a problem, diameter from 12" - 16 1/2" and pitch in any increment from 26 - 35 (true pitch) and 4, 5 or 6 blades.

Between the can, blade design, and number of blades there may be too much stern lift. I am excited about getting our over hub props on some boats for testing, but that may be a few months.

Matt

I'm trying to determine if the Throttle Up props should just replace my Hydromotives, or should I go with shorties and then use their props on my 35?

Julie - any word after you spoke with Matt last week? Thanks.

Hey Rebel,

I would recommend that you investigate the nose cones and if you could get me the prop shaft measurement ( in relation to the hull)...I would feel more comfortable about the possibility of the shorty.

Julie

Thanks for the reply, Julie. I'll get a measurement the next time I'm at the dock. We'll take a look to see if you think my slip will increase too much with the measurements that I take. At the very least a nose cone may help with aerodynamics.

Please let me know when you are ready for over hub testing........

Thanks

T2x

Soon T2x!

Julie

Me to!!

Hello MM,

I hope all is well! I will keep you all posted on the over hub props!

Julie

Sign Me Up For Over The Hub Also. 16.5x35 And Did I Mention Lefthand. Will Their Be Different Thicknesses For Different Hp ? How Many Blades Can You Put On An Over The Hub Prop ? Not Much Room On A Shaft Thats Only 3 Inches Wide !

I am assuming that you are talking about #6 props. Thats the beauty with the CNC machine the thickness can be customized. As for blade count so far 5 blades on both the #6Props and the Outboard Cleavers we are working on.

Julie

Stay tuned new things on the horizon!

Julie

nudge.....nudge....:D

T2x,

Things are moving along, #6 will coming out next followed by Outboards. However, we do have some really great information that we will be releasing very soon! It will take propellers to the next level.

Stay tuned and thanks!

Julie

How much are they?
 

Hello Julie,

How much are the new Barracuda props for Bravo XR's?

Hello Mrs. T,

The Barracuda's are the same price as the 6B's at
$1900.00 each. They are a sweet prop on the correct application. This propeller has not ceased to surprize me as of yet! Call me with the details of your boat and we can take a look at the possiblities.

Thanks for your interest!

Julie

NO ETA as of yet, sorry! But #6's are tracking now!
