Revolution 4 vs. Bravo 4 blade

Hi Guys,

Anyone know the differences between these two props. I know that the Rev. 4 was originally designed for OB's, but ended up also working well on sterndrives. I've also heard that they provide good sternlift - which would probably be good to help pull my rear heavy BBC rig up out of the water. Searching some other forums showed the general trend of 4 blades improving handling, mid range and hole shot, reducing top end slightly. Also seem to be better suited to well/over powered boats - no real surprises with that info.

I saw some interesting slip numbers from a few different sources - the Rev. 4 had very low slip at lower and cruise speeds but it seemed to be even with a 3 blade at top speeds. I wouldn't have expected a 4 blade to be more efficient at cruise - maybe getting the boat up out of the water helps there.

Anyone info about the Bravo's or Rev 4's would be appreciated!

Thanks!
 
what prop are you spinning now? i am running a 24 bravo, after talking with nick i am going to try his out this summer. i think he said its a 23 and they have a little more cup in them than your average 23. he says the 23 rev 4 is about the same a the 25 mirage
 
According to Merc's website, the Rev 4 is simply a 4-blade version of the Tempest. The Tempest is a popular 3-blade that boasts a LOT of bow lift. The Bravo 1 is more of a whole-boat lifter. They have to be worked to get them to be bow-lifters. I ran a Hydromotive Quad IV-XOB, which is very similar to a worked Bravo 1 and it lost about 4 mph vs a Tempest Plus. I've been wanting to try a Rev 4, but not willing to shell out MORE money on props. Another worth considering is the Turbo Fusion 4.
 
They only make the rev 4 up to a 25p and they do act a little bigger than the pitch number they carry. My favorite prop, they have a tone of bite and handle great.
 
i tried it on my 24 io, it performed well overall. best bet is to find one and try it out if possible.
i think itd be worth a try for your boat.

Hi Ross,

I'm spinning a 23p Mirage (with a few nicks) out to redline ~4900-5000K and 65.5mph gps very consistantly. It would run 65.5 very light or with a full tank and 4 people. Ran up over 60mph gps with 8 people once, but I didn't wring it out - might have pushed it out to the limiter but I was getting dirty looks from the sis-in law... I picked up a 25p mirage in better condition and it still ran right at 65mph gps with 4 people at about 4600 rpm. Never did get to run the boat real light to see if it would push it out further. It almost seemed like the 25p had more slip than the 23p. The 25p did cruise at a lower rpm and had just a slightly slower hole shot. I wonder if one of the props had been worked at some point - seems like too small of a difference between them.
 
The Rev 4 is perfect for an all arounder on my 24Super. Probably work good on the stingray, but only one way to find out....:poke:

I'd say its more of an overall lifting prop than a bowlifter.. in between the Mirage+ and Bravo. I don't have to run as much trim as the Mirage.. speeds might be down a mph or two, but the handling more than makes up for it (the boat still runs 75gps loaded up for 3 days at Cumberland). I don't have to worry about the boats attitude off the waves with the Rev4- it flies level and lands really soft compared to the mirage+... the mirage always flies nose happy due to the amount of trim I have to run to get the speeds out of it. I run some tab to counteract that when I need to, but the mirage isn't as good of a prop in the rough for me.
 
Thanks guys. I'll keep looking for a 23p rev 4 for a descent price.

Just need the water to get a little bit softer now.
 
I know I was looking into a Rev4 for my boat but I don't think the 25 pitch is going to be high enough when I get dialed in.......probably end up going with a worked Bravo1 or a Hydromotive. Im planning on just calling BBlades.

The Rev4 is supposed to be a heavy bow lifting prop. If that is what you need then it should work good.....Like engineermike said, it is a 4-blade Tempest. Have you tried one of those? That would be a good indicator.
 
The Rev 4 does not carry the bow like a Bravo 4bld will. On the Z Plane hull of the Stingray hull 230SX the Rev4 is far and away the best prop for handling and speed.

Tried many props on the 230SX and the Rev4 gave it the stern lift needed where the Bravo carried the bow to high resulting in lower speeds and not so great handling vs the Rev4.

Hmm......that seems opposite of what the characteristics of those props are supposed to do.....then again I have not dealt with those Stingrays either. My Bravo I lifts my stern very heavily and does not provide hardly any bow lift. My boat would never air out with that prop.

Likewise I tried the Rev4 on my Sunsation 288 and the Bravo 4bld was far superior to the Rev4. Bravo carries the bow and the boat handles like a dream while the Rev4 seemed to lift the transom and made the hull squirly to drive.
Difference in the 288 hull to the 230SX I had was that the Sunsation 288 has a flat pad. To be honest this is the first time I've ever heard of the Rev4 being considered a bow lifting prop and it's not what I have experienced with it on the boats I've owned or tried it on.
 
I guess hull design plays a major role in how the props compare to each other- espically since some of the other expierences are completely oppisite mine.
My expierence comes from an old school stright bottom 24*V on a very light 24ft boat.

Still, sounds like it'll work good on the Stingray.
