Like most pros and enthusiasts, Pat is continuously tweaking his set-up for improvement in overall boat performance.
Pat noted both Bravo props didn’t care how much weight is in the boat but noticed the engine would tick the rev limitor when the fuel level reached less than half a tank. If your interested in fishing and getting a turn-key, dialed in rig off the show room floor, a Ranger 620VS Dual Console Walleye boat is a great choice. I have just placed my order for a 2012 Ranger 620 dual console (ProStaff) with a Mercury ProXS 250 and a 9.9 Pro Kicker. I don’t have concrete performance numbers but I can help you with some characteristics of the Rev 4. The Rev 4 has a long exhaust tube and can benefit planing the boat but the top end numbers haven’t been that great compared to the Tempest. The Lab Finishing makes the Rev 4 too costly and the durability is not as great because the leading edges and blades are thinned. The 22 Bravo 1 XS gave me great hole shot and very strong top end with full tournament loads in the boat. You will definitely notice increased performance with this hull running the prop over a Tempest.
So, with this information can you tell me with a Bravo I lab finish (or Bravo I XS) what pitch I should chose and what improvement on performance I might expect? I can be contacted via email provided for personal contact information – I would love to talk to you guys! If you’re hitting 5900 with a stock 25 Fury history with other applications tells us you can run the 26 Bravo I XS hitting the same WOT RPM.
The four blade Revolution 4 has a long exhaust tube which adds a tremendous amount of stern lift.
The three blade Tempest Plus on your boat will offer good bow lift at various engine heights. There are several ways to measure engine height; a simple way is measuring the distance from the bottom of the boat to the bottom of the cavitation plate. Pro ET versus the Bravo I XS: for applications that can run the Pro ET, it will offer better top end numbers.
Scott, Got some impressive numbers this afternoon, back to back tests with my blueprinted Tempest 21.
It was pretty windy but back to back tests in like conditions gives me an apples to apples test. Actually had a bit chine walk at 60 mph pretty cool hadn’t seen this since I bought my first Tuffy 1890 in 06 without any load!
Kirt, to answer your question, I want to clarify we are discussing the differences between stock and Lab Finished Bravo I props.
Mercury Racing Lab Finished Bravo I props have a ground satin finish (created by a highly skilled prop technician).
In most applications, our Lab Finishing process results in a gain of 300 RPM over the same prop in stock form. I am currently running a modified Mark Croxton Throphy plus 25 ( reduced to a 24 etc) with all holes plugged except for on medium hole and the plastic vent collar. It will come down to slip; basically will the Bravo I XS hook up better than the modified Trophy? To help understand what to expect when comparing your modified 22″ Tempest with the Bravo I XS, I would suggest you use our prop slip calculator. Scott I am extremely pleased with the Bravo 1 XS on my Tuffy, I have had it for better part of month in all kinds of water conditions.
I am currently running a Yar-Craft 219 TFX with a 300 Verado Pro, boat has Pro Kicker, bowmount, 4 batteries, full of gear, fuel, and 3 200+ # guys i am running 60.5 Mph GPS.

I have a DAH worked tempest 21p that i haven’t ran, i afraid i will lose all kinds of bottom end and holeshot, i mean this thing comes out of the water like a rocket ship. I think we’ll be hearing several success stories as the Bravo I FS gains exposure in the walleye market.
Pat was very receptive to my request for some feedback on our Bravo outboard props on his rig.
The tests were completed with a full fuel tank, tournament gear (all compartments full) and two anglers in the boat, each weighing approximately 210 lbs. If your like Pat, and want to get the most out of your boat, you’ll want to consider our Bravo outboard prop options.
If you’re going to carry a heavy load and you want the throttle response in big water, plus look at the speeds Pat was getting with the Bravo I XS. Getting there was a challenge, we had to stick allot of Lab Finishing (labor) time into the prop.
It offers good planing, good top speeds, is durable, doesn’t care how much weight you throw at it and is available at a reasonable price.
The last one we ordered was for a Gambler with a 300 XS that ran the Sport Master and Prop over a rock!
He says he went to the BRAVO I XS and went on and on how much difference it made all around but especially on his top end.
I can give you some idea of what you might expect but it always comes down to running the props to get accurate numbers.
The Lab Bravo I being thinner compared to the XS offers 100 added RPM (pitch for pitch) bumping you up to 6000 RPM.
The Bravo I XS is geared toward two stroke motors; the vent holes help the engines with bottom end torque for planing the boat.
I have played with engine heights, I noticed the Rev 4 doesn’t like engine height, the Tempest I was able to raise up one more hole vs the Rev, I seemed to bow lift with the Rev when i raised the engine. The stern lift can help when there is allot of weight in the back of the boat (kicker, batteries, live well). To much engine height, is not always good; you can loose bow lift, cavitation can occur during planing and in turns and top speed can drop. To do this, trim the motor so the cavitation plate is parallel to the bottom of the boat, next hold a straight edge to the bottom of the boat running to the gearcase, taking a tape-measure measure the distance from the straight edge to the bottom of the cavitation plate. The exhaust tube of the Bravo I XS in these applications can cause drag in addition stern lift lowering the top number.
The Pro Finish Bravo I XS, as featured in my August 17th post Walleye Prop article, is yet another variant of the popular Bravo I propeller. Stock Bravo I’s feature a high polished finish (created by prep grinding and successively tumbling stones and other media against props mounted in machines). I am running it on Tuffy 2060 dc with a 225 opti , ( it is not an xs) cmc hyd plate 15degree reverse transom wedge.
Might have left a little on the table had to be conservative on motor height and trim because of the rev limiter.
We’ve received great feedback from walleye anglers who have experienced performance enhancements since switching to the Bravo I XS prop for their two-stroke outboard rigs.
One-inch vent holes in the exhaust tube of the XS enables a two-stroke outboard to gain engine RPM and power quicker for an enhanced hole-shot and mid-range punch.
For example, if the boat comes with a 21” Rev 4, you will want to go with a 22” Bravo I FS. This durable prop provides amazing hole shot, mid range punch and top-end speed with enhanced boat handling and fuel economy. Nevertheless, I’m a firm believer of getting feedback from those who use the product everyday in the real world.

The boat was initially rigged and dialed-in with a stock, 21-inch pitch Mercury Tempest  prop. Mercury Racing is the only propeller manufacturer to provide outboard variants of the Mercury Bravo sterndrive prop (see my blog post, Bravo for Outboards, Yes!). It’s hard to beat this prop and going with the XS version it will offer you more durability over the Lab.
The over the hub style prop you have to hammer the throttle hitting 5000+ rpm to bring the boat on plan.
Your new Verado Pro 250 has a great deal of bottom end torque and will blow the prop out making it difficult to plan the boat. In your case, by increasing engine height too much causes the tip of the blades to do most of the work – the Rev 4 has a lot of cup at the blade tip. Could I expect better performance with a Bravo1 xs maybe a 23″ my load various a lot 1-2 people full or empty livewells. A 3-blade prop such as the Tempest can increase bow lift and, with some boats, enhance top-end speed.
Knowing the slip of Tempest prop, you can now get an idea what to expect with the 23″ pitch Bravo I XS.
Scott will get back to you first thing Monday regarding your rig and the potential for using the Bravo I FS with your Verado Pro 300. When comparing the two – the 22” Bravo I FS should enhance your engine RPM and overall performance.
Recently, I wanted feedback on performance differences between our Lab Finished Bravo I and Pro Finish Bravo I XS outboard props. The addition of a fourth blade on the Bravo I XS enables it to run at elevated engine heights, while maintaining an efficient thrust (see my blog post on prop efficiency).
If you can hit 6100 to 6200 RPM, without sacrificing low-end performance under a heavy load, consider going up to a 24″ pitch Bravo I XS.
By lifting the bow and stern, the Bravo I FS provides speeds of three-blade combined with the ride and handling characteristics of a four blade. Dean said the Yar-Craft’s typically handle and ride better with a 4-blade, so I’m not sure the worked Tempest is the way to go.
The over the hub has all the exhaust wrapping around the blades causing slip, so to do the same no wake zone speed the engine will rev 200 – 400 more rpm. This is most beneficial when running under load with the addition of a second person, fishing gear, full live wells and a full tank of fuel. The exhaust tube adds stern lift while the over the hub lowers the stern offering more bow lift (probably not a benefit with all the weight in the back of the boat).
I have an old style Throphy large hub 23 that I tried it won’ t do 58 mph , will the Bravo Ixs get me anymore than what I have right now ? Most 3 blade-props can’t carry the bow when weight is added, reducing top-end speed by 3-4 mph. Hard to tell where the RPM will fall compared to the modified Tempest, but this gives you a general idea of what you could expect. A hydraulic transom plate enables the operator to experience the full capabilities of the Bravo I XS.
