I worked on jet boats for 8 years, the experience is different base on different designs, some can be frustrating if the operation principle is not well understood by the engineer and some are just as easy to use like the kids toys. It's a very good propulsion system.
I installed a similar system on my 8.5 M Sail-Boat off a(KAWASAKI,Supercharged Jet-Ski Motor(310 HP),,with a pneumatic set-up for reverse and controls,took me a week to make-up my mind to finally cut-down the bottom of a perfectly sound and water-proof vessel....!!!...But what a relief and satisfaction when all was installed.After my old tired heavy Penta motor,I could now take my boat on high rough Seas with a super reliable,powerful set-up,already sailed to Portugal,from France and back,fishing on idle but also pushed the engine to max power,lots of torque,now,it's new GARMIN electronics,AP,radar,solar panels all LED lighting and prop,to next year,hit the"big"trip of my dreams to the Philippines.
When I was younger and watched this I thought the impeller was magically powered by water and that this was the way of the future because there was no gas to be burned
Been working on jet boats and jet skis for 40 years.they turn on rails but reverse is horrible and maneuverability in reverse is horrible also.and they are not very efficient
I'm assuming this is more expensive than the regular propeller sticking out? I see this engine as being helpful for conservation of wildlife, actually. I hear a lot about the Florida manatees being killed or maimed by boat propellers. This just has high velocity water hitting them, which I think is much more safe for the survival of manatees.
The jet is also a good idea for boat operators who have a habit of running over swimmers & downed water skiers. Jets are also very good for river boats running in shallow water with many obstacles.
Hi sir,,,, I had question... Does the nossle need to be submerge same as the stirring nossle? I'm just wondering,, cause the stirring nossle might generate a resistance.. Tnx for the answer ..
Detailed explanation is here: ruclips.net/video/C9jGKaiZIcQ/видео.html Watch from min. 8:10 onwards. (edited this comment since my first attempt was competely wrong. Sorry.)
This is a good way of protecting animal and plant life in marshy or lake area from propeller damages. Wonder why this type of propulsion is mandatory in wildlife(aqua) and marine tourism
I'm quite sure the whales would like to see this system on large ships. Ever see a whale with large diagonal cuts along his back? He's not getting ready to be barbecued. He's bee run over by a ship.
Hi How to become an agent for your company, and what are the conditions and how the processing, and your final prices continued to Iraq / Baghdad . We need an email / phone company with sending some blocks to the small and medium boats industry, or any plan or layout with the measurements and sizes of aluminum and measurements of the aluminum layer and the type of engine and parts With respect and appreciation
A company is developing a water turbine that will be used in front of the intake to produce power and feed low pressure water into the pump intake stream
Jet powered boats have more torque, quicker response and are less susceptible to cavitation and a shallow draft making them operate more efficiently at the cost of much greater fuel expense. Turbo-prop aircraft engines have more torque, much lower horsepower to weight ratio(higher useful load), and fewer moving parts that don’t reverse direction 5000 times per minute at 2500 rpm like a piston engine. This makes them very reliable and therefore safer but at 10x the cost. Bottom line is how efficient something is requires a definition of terms. $0.02
High bypass turbofans are getting to turboprop efficiency and prop fans completely obliterate turboprops in efficiency at the cost of higher noise and vibration.

なんと分かりやすい動画。ウォータジェットの動作を視覚的に見れて、仕組みが理解しやすい。（英語はいまいち聞き取れてないけど）
I was curious, I youtubed it, i now know how it works. I thank you. Lol
I feel this exactly

Hahah same here
Yup, same
Same here😂😂😂
the most video ever; thank you 🙏🏼
thought this was one of those “how cat works” with free bird and showing a gun
insane idea. masterpiece of engeneering
Cool! I finally get the point of having fixed stator vanes.
How do you "Crab" or walk to the side as in docking? What position should the buckets be in and what should the RPM be?
Very impressive! Good video!
Is it possible for a small animal to get sucked up in there? Or is there some kind of grate covering?
thank you so much for this video do you can show me how to install water jet?
Thank you for great explanation
This is very impressive technology
great explanation!
When I was younger and watched this I thought the impeller was magically powered by water and that this was the way of the future because there was no gas to be burned
But can it run Crisis?
so good a product the website no longer in business lol, what boat was in the picture it looked very good?
Okay, I'm sold. I want one!
, you can buy product from www.liangtongda.com/
Hook it up to an electric engine and you are good to go.
Does anyone make a toroidal impeller for these jet pumps?
What is a good electric motor that would work with these jet pumps?
Great explanation.. Thank you
Does Kavitation in the jet affected?
..how can i buy one unit of Impeller set only for a small boat Sir Andy?

Been working on jet boats and jet skis for 40 years.they turn on rails but reverse is horrible and maneuverability in reverse is horrible also.and they are not very efficient
Could this work on a mega vessel or would the weight of the vessel be to heavy for it to properly steer or go in reverse
It could work, but it would not be economical.
and how much is this waterjet propulsion?
WE SHOULD INVEST HEAVILY ON JET ENGINE PROPULSION
Wait so it squeezes water out a smaller nozzle with a propellor inside?
In this case, impeller
I am also working on water jet for ocean going marine vehicles like container liner also using renewable energy like solar and wind .
It’s called a sailboat + water hose
Спасибо!

Excellent invention!!!..a boat propulsion and brake system! Would have saved the Titanic.

Can someone tell me why the stator veins are necessary? Why not just let the propeller spin the water?
Unwanted torque most likely, and probably to save energy that would be lost in the spin.
I always wanted to know how this works but i keep forgetting. Now i know.
Very cool video
I guess this Thing's boat?
Such a pour means of water propulsion though

nice vidio! I clear!
where do they burn the fuel?just like air plane jet or what?
the turbine is powered by a engine further up the vessel. notice the drive shaft thats powering the turbine
Excellent
Good invension
When will this come to merchant ships ??

Все верно, но шум создаваемый таким двигателем слышен за много миль вокруг, если это актуально!

I watch this after saw a boat sailed on a shallow river in NatGeo and I remembered about jetski and then searched "jet boat"
There is a new pelton pump jet being developed for submarine
I clicked on this video to get a better idea of how U.S. Navy submarine pump-jet Propulsion works.
what is a beering?
England is my city it's Australian for Bearing 😀😀
Imagine this technique used in submarines
So basically a turbine ?
funny we just built a 454 chev for ours.... 70mph across water is freaky man
could submarines use this method

Super
now i got an idea...
No bubbles

So a jet is a propeller.. but you dont see it so therefore...
REEEEEEEEEEEEE WATER JEEEET
When a big fish come inside the jet then???
There is a grate to stop that from happening.
@@kwerk2011 Might pick up some small fish though. I recall a 6" pump drawing water from a creek. The intake screen frequently got clogged wit minnows.

such unnecessary technology for bigger boats. good for watercraft and shallow draft
a jet will never be as efficient as a prop... whether in planes or boats
you are right, not in boats, but in planes they are more efficient
Props have an increasingly difficult time moving air as the forward speed of an airplane gets closer to mach 1.
Jet propulsion is more effective than propeller.
Jet powered boats have more torque, quicker response and are less susceptible to cavitation and a shallow draft making them operate more efficiently at the cost of much greater fuel expense. Turbo-prop aircraft engines have more torque, much lower horsepower to weight ratio(higher useful load), and fewer moving parts that don’t reverse direction 5000 times per minute at 2500 rpm like a piston engine. This makes them very reliable and therefore safer but at 10x the cost. Bottom line is how efficient something is requires a definition of terms. $0.02
High bypass turbofans are getting to turboprop efficiency and prop fans completely obliterate turboprops in efficiency at the cost of higher noise and vibration.
They FORGOT TO TELL YOU ITS FUEL EFFICIENCY IS NOT AS GOOD AS STANDARD PROP BOATS……..
I wonder if it’ll become improved in the future
