Metal Shark Introduces Swamp Shark All-Terrain Surface Drive

For more information visit www.metalsharkb...
The “Swamp Shark Drive” is an all-terrain propulsion system specially engineered and built for operation in extreme shallow water, riverine, and mud flat environments. The highly durable system will safely and reliably propel a vessel through dense vegetation, mud, and debris-strewn waters.
The Swamp Shark propulsion system consists of several key components: A CNC-cut, machined-steel surface drive, internal/external stabilizing hydraulics, and a specialized internal cooling system, all of completely original design.
Swamp Shark drives are currently available in configurations capable of handling up to 550 propshaft horsepower and 1,250 ft.-lbs. of torque, all while operating in extreme conditions. The specially-designed outdrive with custom cavitation plate features hydraulic power trim and steering, and its stainless steel surface-piercing propeller easily powers through mats of vegetation, bushes, or branches, while offering outstanding control on open water even at high speed.
A patented hydraulic / electric rebound system, which consists of actuators inside and outside of the vessel, allows the drive to smoothly and automatically adapt to conditions. When the drive impacts a solid object, such as a log, stump, or other submerged hazard, it swiftly “kicks up” so that the propeller will not be impacted. The system then exerts reverse pressure to instantaneously return the drive to its normal trim position as soon as the object has been cleared.
Swamp Shark features a fully self-contained, patent-pending, onboard keel cooling system, with no appendages beneath the hull and no need for overboard raw water. This allows for smooth operation over underwater obstacles and allows a Swamp Shark-propelled vessel to traverse shallow, vegetation-clogged water or even loose mud with no cooling issues. The highly-efficient system cools engine oil, power steering and transmission fluid, and also boost-air intercoolers for turbo or supercharged engines, all with no reliance on outside water.
Swamp Shark Drives are available in a range of sizes to accommodate a variety of gas and diesel-powered boats for military, commercial, and extreme recreational operators. Metal Shark is the exclusive OEM installer of Swamp Shark Drives for military and government agencies.
Established in 1986, Gravois Aluminum Boats LLC, and its government/commercial boat entity Metal Shark Boats are leading suppliers of custom boats for defense, law enforcement, and commercial entities. Key customers include the United States Coast Guard, Navy, Air Force, Army, foreign militaries, law enforcement agencies, passenger vessel operators, pilot associations, fire departments, and other operators worldwide. Under the direction of its owner/operator Allard and Gravois families, Metal Shark has produced over 500 vessels in the past three years at its two fully self-contained South Louisiana production facilities. Metal Shark produces a wide range of custom monohull and catamaran vessels up to 250’. metalsharkboats.com.

Imagine showing up to the local bass tournament with that.😂

[@edwardboyer7102]

Nobody in the world can beat this testing out souped up bush thrashing boat just imagine how many boats he has destroyed i love keep mashing on em bro

[@sharkcarsangelle6739]

This Boat and the Drive Still survive to this Day , it Just GLIDES OVER EVERYTHING

[@norml.hugh-mann]

How are these not destroying swamps? And the noise is so loud that your gonna be stuck operating it in remote swamps. Its a good thing 99% of people cant afford one or our swamps would become pits of mud void of much life other than slime

[@sharkamov]

As 'born' in a boat, and as a lifetime mariner of all seven seas, all I can say is; _WHAT A CRAFT!!!_ *Re-spect!* - Greetings from Norway!👍⭐️ ⭐️ ⭐️⭐️ ⭐️ ⭐️

[@strokerace14bp]

Don't even need a truck n trailer,just drive it home! That things a beast!

[@francislong5114]

made my day..

[@Harikarikillboy-fs5vl]

This why I love the people here in southern Louisiana. They took a problem like getting around in a bayou and engineered a system that is superior to any other product. That don't mean I'm bashing the established mud motor companies, I'm saying now there is a new and amazing machine that'll give us all more options. Ok, a really badass kicking butt option. I saw that sequence when he was hauling butt down between the basin bridge but really couldn't see it from the roadway real good, but the beautiful sound of that engine was ear candy and then seeing the rooster tail..dang. I'll take one of each.

[@samtatenumber1]

im nearly certain an airboat could do all of this and more.

[@JsGarage]

This is the run from the cops boat 😂

[@charlesloh2637]

With m-134 minigun mounted, this thing is perfect.

[@jkitto2008]

You should give this to those fellows on the history channel those gator hunters.Old Troy Landry would never come home if he had this. Lol

[@tommyjoestallings3339]

Well that's great... Another man made thing that tears up mother nature 💔

[@stater3]

Speed and sound is just perfect.

[@1Fine69c]

I work security on the river and have been trying to convince the crew boat launches to take me out on the metal sharks. Definitely the nicest boats out there.

[@ScottyBeen1000]

Your mother is nicer

[@trevornewton9687]

These would be perfect for the military

[@ZachByrd]

Would really like to see the propulsion system up close in a future video.

[@meanman6992]

Looks like maybe it's a encased prop?

[@MetalSharkBoats]

No, not encased. I can't attach a photo here but you can see a good shot here: www.metalsharkboats.com/swamp-shark/ -J

[@johnnyllooddte3415]

We would too.. We re not wasting millions on a slick video and cute marketing.. Doc Johnny

[@etackhelicopter]

kzbin.info/www/bejne/nnqsp6tmbrGtpKM I doubt these guys are up to anything cute. That video is close up enough to explain everything. I'm impressed with the package. It looks like I could use the shark to convert boats from jet pump drive, with minimal effort. I can't say whether they can produce these things in masses to meet your multi million dollar demands, but they seem to be doing well. I think there would be sizable market for converting popular Berkly and Jacuzzi drives for performance and utility river boats.

[@pstrap1311]

It's like an articulating surface piercing drive system except they replaced the surface piercing propeller with a giant stainless steel immersion blender and anti-roostertail shroud. Nice.

[@ELCaminoHWY77]

Uh that escalated pretty quick hahah. Two thumbs up brothers!

[@twinturbocoyoteftw]

I need this so I can get to them big bream in early April this year!!!!

[@peterjarnes25]

Good luck getting the ticks outta your ball fro!

[@jag217]

Coming to fragile ecosystem near you!

[@ajsullivan2559]

Can you point me to a "hearty" ecosystem? Every damn time you envirowenies complain it is always about a "fragile" ecosystem... and it seems to me that every ecosystem in existence is "fragile" to you people (yes, I said "you people") so that you can cry about it.

[@leem9886]

Less music. More motor.

[@wsaenotsock9486]

This boat may be metal, but it gives me wood...

[@wesleynichols5255]

Need to put more videos out on metal shark

[@erNomic]

That looks great for the ecosystem.

[@novoice1127]

Us humans are already destroying the planet a couple hundred of these running around the sensitive ecosystems will really benefit us👍👍👍👍👍

[@fishingmojados1121]

Perfect for my Jon boat

[@bradcross6755]

How shallow will these run ? I fish a lot of rivers with some real skinny water some times where a jet is nice but I also fish rivers with a lot of veg

[@user-yy8su7hr5i]

В этом году тоже на таком же аппарате буду ездить, возможно ещё будет круче.

[@maximumhardcore4362]

I’ve got a nice rock pipe I’d like to give this all-terrain vessel a try!

[@thatruthhurts1670]

This is what Shelby needs

[@landonwooldridge123]

I see that there is a prop guard, but what actually absorbs the hit if you run over a log? Straight through the locked out trim strut into the transom?

[@MetalSharkBoats]

We took several high-speed passes over a large semi-submerged log in this video with barely a bump. You'll see the footage at about 1:17. We then switch to a GoPro shot of the drive at the moment of impact and it's barely noticeable (approx 1:26). There's no prop guard. The patented Rebound System, which consists of actuators inside and outside of the vessel, allows the Swamp Shark drive to smoothly and automatically adapt to conditions. When the drive impacts a solid object, such as a log, stump, or other submerged hazard, it swiftly and smoothly “kicks up” so that the propeller will not be impacted (the leading edge of the skeg features a special radius designed to facilitate quick and smooth passage over any objects it encounters). The Rebound System then exerts reverse pressure to instantaneously return the drive to its normal trim position as soon as the object has been cleared. A schematic of the drive and other information can be found here: www.metalsharkboats.com/swamp-shark/

WTF!??? I didnt want this video to end!!!

[@brackishbassin3338]

Now im just waiting for the jetski.. "hint-hint"

[@brandonevans4142]

Im just imagining tons of spiders and ticks crawling on this boat after this video was made

[@MrPottymouth122]

Schweet! Really, amazing performance! Would really like to see the engineering behind it.

[@effreyjeppstein4673]

Can't wait to ride one across North Korea when we finally kicks things off over there 👍

[@norml.hugh-mann]

Stupidest comment goes to you on so many levels

[@DustinApple]

give this a week and it will be Viral! Me and all my bowfishing buddies are going nuts over this footage! just wait till the duck hunters get a hold of it! From a guy who has built a few boats and now a inboard jet (on my channel) I really hope these drive systems will be available for purchase soon. your website isnt working so hot right now. how much HP does the system require and how much can it take? my mind is at both ends of the spectrum already from a tiny turbo motor buzzing in a 1460 to a full on fire breathing big block in a 2484. look forward to more updates!

[@ylastchance]

Dustin Apple screw fishing, let's ride around

[@majorwedgie8166]

Very nice... but I didn't see it once reverse. The design, judging only by what I can see, doesn't appear to have means to back up.

[@murdoctor2016]

Chopping alligators left and right. Nice...

[@AlphaGolf1]

Alligators disperse as soon as they hear anything this loud numb nuts.

[@wesleynichols5255]

That is a badass boat

[@calvinh.8882]

You produce some awesome boats, but I've never seen one in reverse. I know there's no way it can reverse through the stuff it goes forward through, but does it have reverse at all?

[@JamesJones-cx5pk]

Thats a damn good question. 👍 Reverse is essential!

[@patrickverot]

Fiberglass fabricators here. We did your RHIB boats.

[@russellrussellrung4]

I want one of them!!!!!!!!

[@markgoldstein6301]

boat video of the year. this thing is beyond badass. gotta have one of these shark boats.

[@laynestaley4630]

This boat is fit to the agusan march in the philippines where LOLONG🐊 is captured.

[@breezy0037]

How many snakes and spiders fell in the boat by going through those trees?

[@randytruthful1790]

Amazing technology and performance

[@remkojerphanion4686]

This machine is sooooo sick!!!

[@carlaj1972]

Would like to see them make a complete stop in the marsh and then take off

[@MrDavidelliottjr]

That's easy for these

[@ussenterprise5364]

Makes me wish I'd been born and raised in south Louisiana.

[@thegoalie2090]

Many trees were harmed in the making of this video.

[@zacksrandomprojects9698]

That thing is crazy bad ass!! 🍻🍻

[@michaelmixon2479]

I can see the military application.

[@MrSamurichuck]

This is how you destroy the swamp.

[@kritpitako]

Yeah,LS swap. You're doing right. Next is turbo or supercharged.

[@ttgg17]

เฟงลาว

[@dannybarbier9068]

Shelby needs one of them

[@WW-wf8tu]

Interesting you should mention that. When I seen it being powered by a Vette engine, I cringed at all the downtime for repairs.

[@dannybarbier9068]

True

[@dannybarbier9068]

Shelby would put a hole in that in a day

[@joshuarayfield7594]

That skeg is working OT

[@abidulhoque9147]

Just wow..super engineering success.

[@Jiggyjames_fixes_things]

I’ve been looking for something to get me across all those pesky oyster bars down at the coast. No more driving around them!

[@jakedover6292]

I want one of these so bad...😮

[@ryannelson6390]

Aren't those trees protected @Louisianadepartmentofwildlifeandfisheries @ldwf

What happens when you have to back up?!?

[@tgwoolshire]

Where's your boat that backs up?

[@joshh3184]

Is the drive system basically a copy of a arneson surface drive?

[@sharkcarsangelle6739]

Not at all an Arneson would Fall to Pieces , its a Surface Drive but there is much more too it

[@Foxtucky]

Great video

[@get_downed_boi6270]

I would hope a v8 car engine and a titanium propeller could rip through vegetation

[@tgwoolshire]

Would you mind please showing us your version ?

[@jamesritch5245]

That bad boy sounds mean!!

[@lordbwithu2071]

Oh my God I want to come work for you guys ...

[@johndana8671]

Damn good.:-)

[@Crazystuffyousee]

Looks amazing, but still dont understand how its any different than any surface drive other than the isolated cooling system. Is the prop made out of Adamantium.....?

[@MetalSharkBoats]

One key difference is the patented hydraulic / electric rebound system, which consists of actuators inside and outside of the vessel, that allows the drive to smoothly and automatically adapt to conditions. When the drive impacts a solid object, such as a log, stump, or other submerged hazard, it swiftly and smoothly “kicks up” so that the propeller will not be impacted (the leading edge of the skeg has been radiused to facilitate quick and smooth passage over any objects it encounters). The rebound system then exerts reverse pressure to instantaneously return the drive to its normal trim position as soon as the object has been cleared. In the video, at around 1:15 and again at 1:20, we make a couple of high-speed passes over a floating log. Then, you see the same pass as captured from a Go-Pro camera mounted on the transom. You can see the drive pop up briefly. On a conventional surface drive, this kind of impact would likely shear a blade off the prop. We'll post some more videos that show this a bit better. The drive can easily absorb and react to impacts that would cause catastrophic damage to conventional systems.

[@WW-wf8tu]

@@MetalSharkBoats Well, you explained that a bit more technical than I did on your behalf to another viewer above. lol But I think I got the same principal function explained. You have taken the concept of an off road suspension system and applied it to a marine prop drive with skids or "skeg". Which is brilliant.

[@slevincolebra6635]

That's CRAY.

[@6613steven]

this video screams violence how that boat was attacking the foliage.

[@edwardboyer7102]

Ya know this boat is honestly to much an God knows I want one but ah standard center console is enough for me I'd kill myself drunk testing it out amazing boat

[@onebaddj]

love this boat

[@radar942908]

Hello! Please tell me that you use a drive of equal angular velocity to rotate the shaft?

[@tgwoolshire]

Please tell me you have a boat of your own you can show us videos of ????
