Turbo TXP props

[Toffen]

Hi!

I hope you all are well :)

The best prop for my set up is a labbed Rev4 25 pitch prop. The only downside with the prop is that it can not be jacked high enough. It has lots of bowlift, so its faster than a Bravo 1 prop despite the Bravo 1 prop being able to be jacked 1 inch higher than the Rev4. The consistent top speed I get is 81 mph at 6,500 rpms with 1.75 gears. Not bad really for a 30 years old no stepped,no notch 2,850 lbs hull. I have lots of waterpressure (35 psi..), but if I jack the engine up higher, the prop loose bite.

I have testet stock Bravo 1 26, labbed Mirage Plus 25, Tempest 25 A45, Hydromotive IV-O/T 25, etc. The Rev4 is by good margin the fastest one.

Have anyone you testet Turbo TXP props - 3b and 4bl. If I am correct they like to be run high and still being able to hold the bow. The lower unit on the Verado 350 sci is massive 5,44 diameter, so the clue is to get it out of the water.

Thanks!

Cheeers, Toffen

[dnelson964]

In general the TXP 3b can run higher and is faster then the 4b and has alot of rake to carry the bow. I would give one a try...GL.

[Mr. Demeanor]

IMO opinion the Rev4 lifts the entire boat. That is why you cant lift it as high on you jackplate gauge, it is already lifting itself in relation to the waters surface.
Its probably actually higher in relation to the waters surface than the bravo.

[steve@scp]

when run UP HIGH.. the txp o/t4 is much better than a 3 blade.

still very good grip up high.

another option would be to have your rev4 worked for grip up high. i've done several with very good results. as most shops i know of do the same.

if your interested in a txp give me a shout. i stock them (as best i can). they sell fast!

[phantomuk]

how do the txp compare to rakers?

[steve@scp]

3 blade txp vs. a raker??
similar geometry. with the txp having more progression and .25 larger diameter.
thicker blades on the txp.
txp have a square bore hub cavity. and have the option of pvs holes.
rakers can be drilled also.
the txp has slightly more rake than a raker. but they are close.

txp's have a lifetime warranty.

the Raker II's ? yuk. too soft, but they run well on some boats. made in malaysia by solas.

[phantomuk]

yes, im not a fan of the 2 i only use mk 1 rakers.
i have used the small hub and big hub over the years.

[Toffen]

Hi!

Thanks:) My Rev4 was modified to run higher. I will speak to my propguy if its more to be done to the prop. I bought it second hand and it was tuned for a stepped 28 rib hull. I have a straight non step non notch v hull.

I will also try to borrow a 4bl TXP too. If it can be jacked higher and run lets say 80 mph in stock form, it will be a potential there. A 3bl TXP will be tried too. Do anyone know how much rake a Rev4 has vs TXP? And is the bladearea the same. Both are important for my set up.

cheers and thanks, Toffen

[dnelson964]

The TXP-3 will be hard to beat at top end and has the most rake at @ 34 degrees...Just sayin...

[steve@scp]

i just measured a 24 txp 3 blade. rake is 30 degrees.
measured an original 26p Raker. rake is also 30 degrees.

measured below the cup line.

That's great info Steve thanks. Could you measure the rake on a 3-blade 29 TXP ? I have a Yamaha T-1 29 and it is like 34 degree rake. I know Yamaha bought out Turbo and was not sure if the T-1 Yamaha props are possibly just modified Turbo style props with similar TXP-3blade ears or did they increase the rake?

Would be nice to know.

[steve@scp]

i don't have a 29p txp. however i'm sure the rake angles don't change on txp's like other props do.
i will measure a 29 o/t 4 that i have in here. it's dead on 30 deg.

Yamaha bought turbo as turbo had been making yamaha props for a very long time. it was a business decision to own
the mfg of the props.

btw.. jmho. the T1's are hard to measure rake as they are Parabolic raked. "massively" just depends on where the bar sits on
the blade when you measure it. when measuring rake the bar is supposed to sit below the cup line.

[dnelson964]

Steve, what is the rake on a 32 Bravo I ?

Read some where the T-1 had most rake angle at 34 degrees and had picture of it with straight lines of measurement.

[steve@scp]

if i remember right. bravo's are around 25 or 26 degrees rake.

[LaveyT]

Hey Steve,
Not to hijack this thread (good thread) but... I have been running Rakers for along time as well as SRX ect ect. The Rakers are the best but it appears that I need more Diameter to be able to raise my engine any higher and still get killer bow lift. Stoker recomends a worked Bravo 1 (28").
I was also curious about the Yamaha T-1 (Vmax) (same thing?) in the 15-1/8" diameter vs a TXP 4 blade or a TXP 3 blade. Even my best surfacing props run no faster with my engine any higher than it is now.

[steve@scp]

rakers are 14.5 diameter
txp blades are 14.75 diameter

jmho. i wouldn't try to truly surface a T1. it will break!!

a worked bravo is a good idea, and so is a 4 blade txp. when you put more blades in the water while surfacing they run smoother and have less oportunity for blade failure.

i ran a bone stock txp o/t4 in a 29p on my bullet at 1.5" above pad.. ran 92.4 with no chine walk. drove like it was on rails.
in my opinion the idea of surfacing a prop is to keep everything running level and let the props geometry do the work to lift the bow (slightly) and maintain all around boat lift.
make sense?

[LaveyT]

Yes it does make sense. Im not sure how much natural lift this thing has. A nose cone will kill this set up. I have gotten 84mph with the stock case but that was years back with some interior removed in cool weather. Im pretty sure these cases are good untill about 86mph.
I lost a prop shaft (and Chopper) @ 94+ and it just sat right down. That was with a worked 260 it had a cone of course and wanted to hop around 80mph. I used to put the passenger in the rear of the boat or it would not get thru it. Bow lift (and nose cones)are the reason most guys dont see decent numbers with these hulls.

[steve@scp]

i am enjoying learning about the variety of boats on scream and fly.

[LaveyT]

Whats your gut say? TXP 3 or 4 or Bravo 1? I think Im looking for the ability to lift the bow with the motor higher than it is now.
If I cannot suface it maybe the T1?

[steve@scp]

i'd go with a txp myself.

price,warranty, and performance is excellent.

i sell a ton of txp's. from bass boat,to fast boats, and etc.

[LaveyT]

Three or Four blade?

[steve@scp]

personally i'd go with a 4 blade.

i've had guys run the 4 blades and they scared the crap out them with the lift the 4 blades give.

[phantomuk]

In europe we mostly run offshore type deep v ski boats....usually heavier as the water get rough

Check out www.boatmad.com. jay smith and quite a few people from here are members

[LaveyT]

Thanks Steve!
Maybe this spring I will look for one to spin!

[gm250]

i'd go with a txp myself.

price,warranty, and performance is excellent.

i sell a ton of txp's. from bass boat,to fast boats, and etc.can you post a pic oftxp and what pitch is avalible

Thanks that helped alot

[steve@scp]

txp 3 blades i will sell to scream n fly members for 399.00
txp 4 blades are 420.00
most already have pvs holes.

shipping is flate rate 18.00 in the US!! (48)

[dnelson964]

Steve....With your experience can you give us any comparison between the TXP o/t4 and the turbo fusion 4 (large hub) ? I am just guessing but does the fusion offer similar speed w/same pitch but additional stern lift due to the large hub?

[steve@scp]

i bought a few of the fusion to see if they were similar to the rev4 by merc. NOT EVEN CLOSE!!!

i wholesaled the fusion's and never bought another one.

p.s. what i was trying to find was a prop that would compare to a rev4 or bravo I. haven't found one yet, other than a hydromotive.

Hill Marines bravo style prop is okay, but needed alot of work to run with a bravo I. Hering's B1 4 blade is killer! i gave them some specs
for one i wanted and it's fast!!!! and virtually will never break... but it's 1550.00!! ouch. simply the prettiest prop i've ever seen.

Interesting.....what was the handling and speed like with the fusion? What would they be good to run on?

[steve@scp]

we ran them on bass cat's and 1 ranger.
holeshot was great, handling was great. speed was 5+ slower than a txp.

if i remember the guy with a bass cat puma kept the 25p as a ski and play prop with his family.
the other one went to a guy with a ranger fisherman series with a 225 opti. worked pretty good on that heavy rig.

[Toffen]

Hi!

How will you compare a 3bl TXP with a Tempest? Will it give better bowlift? Can it be run higher?

Cheers Toffen

[steve@scp]

the tempest is a great prop.
the txp's run very similar. i do alot of testing between the two.
matter of fact i just ran a z8 nitro with a 225 pro xs. the 26p tempest ran better than a 25 or 26 txp

just depends on what the boat wants.

[kostas74]

How is 3 blade TXP compared to a Fury?
I've tried a 24 Fury and it's very fast but i could use a little more bow lift,does TXP offer that?

[steve@scp]

the fury is much faster on the holeshot.

the txp is known for excellent bow lift.

both are very good props, and i get different feedback comparing them both. some like the fury and some like the txp.
just depends on the boat.

[kostas74]

What about rpm,are they similar?

[steve@scp]

rpms are very close between the txp and fury.

txp vs a tempest. the txp will drop your rpms.

[kostas74]

Thanks,this is the info i need to choose the correct pitch:thumbsup:

[kostas74]

Steve do you ship to Cyprus?

[steve@scp]

i'll ship anywhere in the world... cept those at war with us. (combat vet that I am..wont do that)

[kostas74]

Ok thanks,i will let you know.

[Greg G]

TTT ........ I stumbled on this and it's got some really good info.

[wettek]

Gidday Steve

Running an old 23" Shooter (OMC) to 6000 an a heavier ski boat with a 175 Evinrude. Keen to try something newer,
and I'm hearing lots of good things about your props. A lot of reports say the Shooters were pitched high (ie a 23 was actually closer to a 21)
just wondering what your thoughts on this were and what your recommendation would be. I'd like to keep the rpms around the same.


Thanks mate, regards to all

[steve@scp]

the pitch on the shooters is accurate. they are just small diameter props with very little rake to them
making them easy to turn, especially on the newer engines.
if your r's are good with the 23, then a 22 raker or 22 RK3 (power tech) or a 22 txp will be great.
you will need to run any of these props a little higher on the jack plate.

[wettek]

Thanks Steve. Do the TXPs come in 22, they only appear as 21 and 23 on the website?

[steve@scp]

i don't think so. for some reason they skip the 22p in the txp

but the lightening is made in a 22p. i'm not a huge fan of the lightening prop. but it does
work on some boat/engine combo's .. mostly the older engines.

[dnelson964]

I have experimented with the TXP and the lightning and seems if your boat likes alittle more stern lift then you will like a turbo Lightning. JMO

[Greg G]

How does the Turbo TXP compare with the Turbo Fusion 4?

[steve@scp]

i played with modifying the fusion 4's and never even came close to making that prop run good.

[phillnjack]

is that true that the raker mk2 is made by solas in malaysia ?

if so that's put me right off a mk2

phill

[steve@scp]

from my understanding BRP is having Solas make all there props now. and yes, they are made in malaysia.

if your looking for a raker (or close too) blade design. then the power tech RK3 or the turbo txp are
the two closest blades to that design.

[phillnjack]

have any of these props got a bit more rake than a raker ?

phill

[steve@scp]

the Raker II has alot of parabolic rake in it. it has too because of the soft metal.

more rake? i would say no.(about the same) but they do have more progression and higher cup heights than the original raker, but not
as much as the raker II.

[phillnjack]

I am pretty limited I think to the make of props due to size of gearbox, mine is the omc triple with 2.42 reduction and I think about 4 1/4 hub with the 13 splines same size as the old v4 140 gearbox.
I am trying to find what will give the most bow lift possible, my boat runs too wet. I
I have tried a silver streak/srx but that dont get the front out the water enough. not much different to a sst to be honest.

has 15.2 dia. and claim 40'rake i run it high with only small torque compared to a chopper no nose cone boat loved it. now with 2.4 220 mag with cone runs 75 but i think the bobs lower is slowing me down feels heavy even thhough i gained 8-10 mph from the 150 the 220 came with coned lower really wanted stock 1.87 needto trade for a stock good 1 87 CLE too much $

[Magcat 62]

i saw a post about a 21 super boat plain v hull ran a scorpion and said best prop ever just had to drill larger pvs holes. i had to do the same they have as claimed parabolic rake huge cup i heard there made in NEW ZEALAND

[steve@scp]

i may not have been running it high enough... good info.

give power tech a call. they may be able to help you. 1-800-736-7767 or shoot them an email.

[P21 Carrera]

the tempest is a great prop.
the txp's run very similar. i do alot of testing between the two.
matter of fact i just ran a z8 nitro with a 225 pro xs. the 26p tempest ran better than a 25 or 26 txp

just depends on what the boat wants.

Steve or anyone with experience on the TXP's.

The best prop on our race boat with a 150 ProXS has been a 29" Tempest Plus at around 5800rpm. However, the Tempest is slightly short. As Merc doesn't make Tempest in 30" I was planning on testing the TXP 3. Can you give me some pointers on whether to go with 29" or 30" TXP 3? I've heard the TXP is rather stiff... We've just briefly tested a 30" TXP OT4 and that lost quite a bit of revs compared to the Tempest 29", but was still about as fast.

[steve@scp]

the txp does run 1 to 1 1/2 degree stiffer than most most props.

two options that will work great for you.
1) get a prop guy to blueprint your 29 tempest to get the rpms and performance increased
2) 29p txp will pull your rpms down slightly
course a 3rd option is both!! :)

Thanks!

Will try to get a local prop guy to work on the Tempest 29".
How would you compare TXP 3 vs TXP OT4? Is the 4-blade even stiffer or would a 29" TXP3 compare with a 29" TXP OT4?

[steve@scp]

they are same blade geometry
adding a blade does effect rpms and lift characteristics.

[whipper]

Steve great info on props! Im thinking about trying a 27 TXP ot4 on my 225PM GrandSport. Im kinda torn between the Solas Scorpion 27 or TXP OT4 27? Any thoughts? i want hole shot mid range and decent top end. RPM is 7500 but keep things around 7000-7200 tops for the most part. 28 Drag3 was my favorite but doesn't like to carry passengers very good. What prop of these two you think would suit what i described or both equal? i love my 25 trophy but not enough top end but great for everything else.
