Love watching this vid. A marine propeller is a thing of beauty. Been around boats since i was a kid and it blows me away how fast a boat can go with so little of its props in the water. Awesome!
Fantastic! Heavy cavitation at the beginning, then the props progressively hook-up, which pulls the RPMs down, followed by acceleration to top speed. Perfect demonstration of surface drive technology.
@@macmacc7402 That would take quite some time to explain, so I recommend a quick search for "propeller cavitation", then you will know everything on the subject 😉
@@macmacc7402 He used the wrong word. Cavitation is when the water boils from the low pressure on the low pressure side of the prop, causing air bubbles which can erode the surface of the metal. What he should have said was ventilation, which is when air gets around the prop and reduces its efficiency, sometimes drastically.
Sigholtz the bottom half is the only part putting down power. The top half is just pointless drag. Take your arm and force it in a circle. It goes fast at the bottom.🤙🏻
+hogheadv2 Thank you and because you can see how the props work so well with no resistance from the water during forward movement, I posted this particular video. Also, this is not a flat bottom ski type boat, but a V displacement hull which is even more difficult to attain higher speeds.
Our 40-ft skater cat we had Arnesons two Keith Black 508 normally aspirated fuel injected 900 horsepower a piece at 7,000 RPM, Got a lot of looks whenever the boat was lifted out of the water. Right away the $35,000 worth of props came off the shafts and were stored in lock boxes. Good old days at Pacific offshore
why dont we have this on regular boats? I dont buy the " not enough power" answer cuz its about the design of the boat. You could easily make a boat so it goes like this, just make it heavier on the front and the propellers will come up. ' So why dont we have siurface drive on regular smaller boats?
Kuk Huve ideally, if you could get the boat sitting on just the bottom of the props, with the minimum contact between hull and water, that's the way to go. Racing cats tend to try for just a skeg and prop in the water if they can.
I had no idea surface drives were even a thing, crazy how it can go so fast with the props half way out of the water. Now I have to learn all about this.
Newtons third law of motion the conservation of momentum, the greater the mass of water the props can throw at the highest velocity the greater the force pushing in the other direction, with the props just picking up water on the surface and throwing it backwards at a slight upwards angle into the air with no resistance from other water they can throw a far greater mass of water faster. Same principle with rocket engines they work better and better with increasing altitude and decreasing atmospheric pressure and have maximum efficiency when they reach the zero pressure of space where there is no atmospheric gas to slow down the exhaust gas being pushed out of the rocket nozzle.
having grown up in the Florida Keys in the early 60s through the early 70s I appreciate service drive for skinny water running, however that is such a beautiful sight in the props at speeder almost totally in sync kudos to the engineer, did a great job
This is a very effective drive system for fast planing boats. Usually these props have more blades or wider blades than normal props. That makes it possible to have prop hubs and drive axle above the water as these components generates a lot of drag. The prop has still enough blade area in the water with only the bottom third of the propeller soaked.
For some of the viewing, the propellers are at just the right amount of pitch to friction in the water to RPM and hp when everything is going right it's just like a propeller on a airplane you have maximum speed, it's doing perfect balance of the forces against it. beautiful.
At the two minute mark it looks like he enters a gentle turn to port and up through the 2:20 point it sounds as if the driver has increased throttle. How fast is it running at the 2:22 point, for instance? Surface drive technology fascinates me. Very cool vid.
That is amazing. Less than half of the propeller is in the water and it still pushes a 40 foot boat at high speed. Dang that's alot of converted energy.
Any boat that goes real fast uses Arneson drives. They are about bullet proof. And when you start making big torque and HP its just a matter of time and the out drives fail or just wear out. The surface drives also use less power to turn them.
I didn't know surface drives were a thing, I honestly don't know hardly shit about boats, however now I know this is a thing. So now I know what my next search will be on TH-cam.
What an awesome video. The only thing better would be to have video on the gauges and one camera facing forward or to the side and then crop all three together in one video. Thanks for posting.
I've always liked Arneson drives since I did some research on them for my trimaran but I never tried one b/c I didn't think it would work on my boat. I believe Magnum Marine uses them on every boat they build. RIP Howard Arneson possibly the greatest inventor in Marine history.
That's awesome. Never seen that before, nor knew how they propelled the boat. Why are they nearly out of the water, yet still going so fast???? I always thought the propellers were completely in the water. Fascinating
Yes. On the Mekong River you can see the very long , narrow beam, shallow draft boats, that have what looks like a V6 or inline 4 mounted on a long shaft, to a prop that they raise or lower into the water and push from side to side for direction. The speed is controlled by what looks like a motor cycle twist throttle. Very effective.
I was a little kid when my dad explained that real fast boats only have half the prop in the water, which sounded crazy, but I he wasn't wrong. That was when turbine engine hydroplanes were coming on to the scene, and piston engines were the old guard.
Not so. I prefer Arnesons and will work with Rik any time before having to deal with Merc racing and all their BS. But there's no denying that the M8 are and the SSM8 were VERY competitive drives. The only two drives Fred and Mercury has truly hated was the Sage 8 and the Weisman drives. Those they got banned from competition. Funny enough the original dry sump SSM6 which was a true dry sump, was built by Pat Weisman. Then Merc bought those two and made the sime-dy sump version that was on the 900 Poker Run and later SSM6 equipped packages.
What do you mean middle of the road? When it comes to high speed drives , the ASD #10 is the end of the line. The others are more suited for large commercial vessels
That is unbelievable to see the props nilly out of the water And it's fucking moving that fast incredible That was great insight on this Thank you for Sharing Great video 📹 Australia 🌏
I was an aircraft mechanic for thirty years. Propellers are designed to the point of least compromise. For example, a two bladed propellor as on a small aircraft is a design compromise between power and speed. The ideal small plane propellor would have only one blade with a counterweight mounted opposite the working blade. This would allow the single blade to rotate through undisturbed air giving it greater efficiency. The propellor blade is in fact an airfoil much like an aircraft wing. the back of the blade is called the working face of the blade
Is this the 399 Skater V bottom that was rumored to run over 100 mph with stock 525s? I remember the Spiderman boat was a Skater V. Lucas Oil also ran a Skater V. If this is a pleasure boat than it’s super rare.
This is an awesome fish blender. Sushi anyone. LOL. But these things REALLY work. Normal prop slip in the water is about 25%. These things run 4-5% only.
Mad props to this guy

Interesting, I was wondering why the RPM drops as the drives are brought up to pierce the surface!

@@crankinbass5758 ...Your comment is nonsense. You're saying the propeller is faster on the bottom? Nonsense, and stupid

Awesome!

I'm a pilot and that is the second coolest thing I have ever seen.bad ass boat, I give you a solid 10 Sir.

WTF are you talkin about
I saw this video once years ago and have been looking for it for that last couple years. Glad to find it again.
I worked with a guy who was making some big split-sleeve black plastic thingies for Mr. Arneson back in 2004ish. Those things rock!
This is the ultimate video of "a boat hauling royal ass." One of the best boat videos...if not the best...fast boat videos.
perfect results from the king of strong propellers by producing enormous thrust I admire it
In prison

"Don't drop the rope"
100th time I see this. Unbelievable, unforgettable... it's like it never ends, until it does!
Awesome... Look at those props, looks like less than 1/2 of them is in the water!! Beautiful.
Damn the props are going so fast at points it dont even look like their moving
That is amazing. Less than half of the propeller is in the water and it still pushes a 40 foot boat at high speed. Dang that's alot of converted energy.
Yeah, but, doesn't this boat have 4 of these props? Looks like the other 2 were underwater.
@@ronaldgreen5292 no only the 2 you see are all that pushes it

Thrust motors excepted.
And boats that go even faster use BPM drives.
how fun --- I worked at Arneson Marine building these ----
when?
Wonderful footage! Surface drives rock!
Smooth as can be and seems to be going about 150. That thing is movin
Imagine being able to go back in time, and flying past a pirate ship in one of these..

I know they are surface drives...but i have never seen one live ....wholly cow thats a beauty
Amazing how much weight is being propelled considering how little surface area is creating movement
Good job guys...long live Surface Drives
what kind of props are they because i want to build something like this for my own project that i would like to do on remote control

Much less drag. Google how surfacing drives work.
Thinking of a similar setup on my 14' flat bottom
Would love to see this videotaped with a slow motion high speed camera...
Thailand and Vietnam has boats that been doing the same thing for along time. I would say this prop has a higher performance output tho. ;)

So I'm guessing this boat would be great for skiing and tubing?
Prince Bytor Frunobulax
Sure until your ski tow rope gets slack in it and falls into the props, it would reel you in like a dead tuna
A bit late, but what an awesome video...that is the coolest shot 👍
Reminds me of my wife’s kitchen-aid at Christmas time.
amazing how fast it goes with the blade only half way in
Indeed. It would be 10+ mph slower if it had a submerged drive.
Nice vid showing the prop transition thru the power band..
Thank you Howard!
Are we there yet ....
I mean its moving but wouldn't the prop being completely submurged be more effective?
The propa have enough blades to absorb all of the engines' power.
Good job guys...this is the future of marine propulsion
Future? They have been around for decades.
You gotta give the boat props
The "middle of the road" drive unit handles 3000 ft lbs of torque. Sick.

Wholly hell! How fast is that thing moving?
Probably around 150 mph
Probably like 4 mph I think
I believe it ran in the high 80's here. It's a diesel after all. It was made to break long distance records, not run fast.
wow amazing props not as much wash would have expected far more
You should totally film it with a high speed camera.
Yeah the slow mo guys need to get on this boat and make a vid for us lol
It still amazes me how these surface drives can be so effective with only 1/2 the props getting a bite on the water.

I think of it this way, water is hard at speed.
It would help to know the weight of the boat, hp? Rpm? Speed?
12,200 lbs, 480 hp, 3,450 rpm, 82 mph
