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.
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.
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
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.
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
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
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: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-C9jGKaiZIcQ.html Watch from min. 8:10 onwards. (edited this comment since my first attempt was competely wrong. Sorry.)
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
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.
