Jet Boat Test Runs on Charlie Lake
HTML-код
- Опубликовано: 13 май 2013
- Two turbine engine powered race boats do some testing on the lake. These boats normally race on river courses, so a nice calm lake is a piece of cake, but we're just doing a quick test of the setup before heading off to race.
Maximum speed is not the goal here, but both boats went just over 125 MPH on this day.

350 lbs, 1250 Hp, and longer service intervals between overhaul. Plus, the T58 was designed to reliably produce 1250Hp for hours, days, weeks at a time.
The piston engines have been highly tuned and hot-rodded to get near that level, and are more highly stressed.
Also, yes, a very large cool factor, don't you think?
Always thought that was the biggest advantage of a turbine. Its designed to produce that kind of power all the time.
A completely outrageous Hemi bored stroked supercharged and maybe sneak a cup of hydrazine into the fuel will produce 10 times the power but only for 5 seconds. And the a complete rebuild in less than 90 minutes. I like to bend wrenches myself but that's a bit much.
And then there's no trip to the racetrack that's complete without a pickup truck box of broken parts.
Although I the Yanks should have come to us for the Turbine/Diesel setup on their LCSs. Canadian navy has been making that work for decades. Seeing a full size destroyer coming up on plane is pretty impressive. Even more so when you don't tear up the gearbox.
What incredible engineering. Beautiful.
That is literally flying. On the surface. But it's flying. You guys should be proud. Good night.
I never grow tired of hearing these boats running! Just reviewing some classic video on a Friday night & thanks again Jay for all of the effort you have put into sharing.

"Hey Grandpa, can you tell me about the time you were a jet boat racer?"
"What? Speak up, boy!"
I read this in Grandpa Simpsons voice
Thats so cool! I love the sound of jet engines spooling up!
A few days after this little test on the lake, these boats were on the river,running over 135 mph according to GPS.
You sir have my respect for your modest behaviour
There are many training programs to make you an apprentice gas turbine technician. I did that and other things. If you built models of aircraft when you were a kid, and have to stop what you are doing to watch an airliner take off, you'll do fine.
The engine makes no power at idle, so letting off the gas pedal causes a huge deceleration from speed.
Also this design uses a free power turbine. Please see my video on power turbines.
New parts are expensive for both. On the ground, the FAA doesn't care, so many owners use the parts until they wear out - something you can't do in the air.
Your little turbine will be cheap because it will be shagged. It will still run, but the FAA inspector would call it garbage.
I'm amazed the water jet can deal with that kind of power! Love these videos!!
I hate myself when I love something really impractical. I imagine it's a lot of work to maintain and run boats like that. But I Fucking love it.
I love that sound when the starter has the compressor up to speed and you add fuel - whoosh :D
tac tac tac tac WUMPFT!
that looks like so much fun!
Thanks for sharing this, Jay.
That is one bad ass ride!! Congrats.
These are shakedown runs to test out boat setup. And Bob is a very experienced race boat driver. Timid is probably not the best word to describe his driving...
Allison/RR 250 C18 is 320 Hp. C-20 is 400Hp. They both weigh about 150lbs, and have an output shaft speed of 6000 rpm. They would fit in a large, modified Jet-ski.
In Jay Leno's bike Y2K, I think the engine is a C-20...
Looks safe and affordable
Sorry, we're not taking applications at this time.
Obama said the same about Obama Care !
Now That's Funny,,,, You Funny Man,,, Very Funny...
Job Applicant Affordble... haha. U crack me up man
So very cool to see turbines going into boats.
Our Berkeley jet pump boats that a frend of main and I had were powered by big V-8's - very very loud yet only about half the top speed!
Awesome wallie fishing in that lake 👍
I love the rooster tail that comes off the back of these things.
I've often thought that a wing up front with some stabilization would be nice to stop porpoising and blow overs and the like. Looks really nice on the water. Like SERIOUS fun!
One of these boats was clocked at 136 on Labor Day.
Hi Jay, thanks for taking the time to make these videos, find them very interesting. In a marine environment (such as when used as propulsion engines in a warship) does the salt in the air have any impact on the performance of a gas turbine? Specifically, would salt deposits build up in any part of the engine? If so, could these be removed with the engine in situ or would the engine need to be removed from the ship and cleaned as part of an overhaul?
That certainly catches you off guard hearing the electric fuel pump go on then the turbine spins. Cool, very cool. Very nice boat. Congrats.
The second thing you hear in the starting sequence is the electric starter motor engaging.
I was a Jet Engine mechanic in the Navy and understand it. Again, very nice boat.
The T58 has an integral reduction gearbox on the PT, which turns the roughly 18,000 rpm into an output of about 6,000 rpm. A helicopter then feeds that into another gearbox that turns that into main and tail rotor drives at their appropriate speeds.
Instead of the helicopter main gearbox, the boat has an otherwise conventional jet-drive system which can be driven by a piston engine running at 6000rpm, or by the turbine engine.
AgentJayZ so my 87 octane pumpfuel injected 3.0 Yamaha DOHC that churns out 8,000 rpm would be a perfect fit for the flying boat....?????
AgentJayZ who cares! Get that noisy piece of shit off the lake!
These are helicopter engines, and the helicopter fuel control is used. The pilot selects a percentage of main rotor speed ( usually 100) that he wants, and the fuel control adjusts the power output of the gas generator to keep the power turbine ( which is mechanically connected to the gearbox driving the main rotor) within 1% of the selected speed.
Helicopter fuel controls are incredible - if the boat were to jump out of the water, the PT speed would not change at all.
Thank you J,,Great video,,TY73s
You guys are so cool! I'd love to pay a visit some time. Keep up the crazy cool work!
I really liked your clip.
Amazing boat, great park job too!
Hell of a jet pump to handle all that power!
The minute or so of idling as the boat comes in to the trailer is plenty to stabilize the engine before shutdown.
I've inspected the turbines of both these engines, and they show no signs of heat stress.
Wow awesome boat. Sounds like a tie fighter when its tearing past.
Yeah I was just about to leave that comment too - but I looked first to see if anyone else had made it. The pass from left to right after 7:30 sounds pretty damn close to a Tie Fighter! In fact, I'm gonna find some tie-fighter footage on another browser tab and watch it with the sound turned down and this turned up just to much around and convince myself! And then after THAT I will start doing some work. Absolutely.
Great boats and awesome passes. Questions for you? Is the conard or forward wing on a gyro to control the hull attitude or is it human controlled?
smooth water, smooth engines, smooth passes!! great!!!
Wow, an on -board starter....well done.
Thanks for clearing that up.
If the sound of that thing going past doesn't raise the hairs on the back of your neck then you are probably clinically dead~
Awesome video !! You really put the "Jet" in Jetboat :-)
The driver controls the angle of the forward wings with an electric screw-jack actuator. The up/down buttons are on the steering wheel. What he does with them and why... I think that is proprietary team information... and I don't know anyway.
Those boats seem perfectly set up.
Is the airfoil elevator? canard? on the front controllable while on the move? If so, it's something that's been lacking on high speed boats for ever. (as far as I know).
That's wicked! I want one.
JayZ nice video, and great job in that t58 last summer =)), i wonder if the tje outlet side up (for obvius reasons... you couldn't turn it donw...) helps the stability of the boat, to sit fermly the back of the boat on the whater, or if it makes no diference . and one more, the outlet has enough thrust to help move the boat, or this thrust is overtake by the whater jet from the propulsion system?... thanks!! you do amazing videos, and share priceless knowledge!!!
You get the hull from Eagle Performance in Alberta.
You supply the T-58 on your own
Pump, jet nozzle, Casale box, seats, steering, batteries, bilge pumps, fuel pumps, oil coolers,and gages are all commercial items.
Then you take about 100 hours assembling your boat.
Then spend many hundreds of hours testing and sorting out the setup, making sure it works.
This particular boat, no longer wearing CDN1, but number 357, is for sale.
Where is the listing located
Got the opportunity to ride in a cat powered by two blown Hemis on Biscayne Bay, Fla. up to 200MPH. Not sure how many folks have experienced speed on water, but its a completely unique speed experience. Was absolutely the most fun I've ever had in a boat!
The power to weight ratio of jet engines is so much greater. this engine weighs around 177 kilos along with the gearbox and is capable of producing up to 1250 horsepower (from wikipedia)
Up and out of the water at 7:43. Thanks for sharing!
Like the wing up front.
Crazy Stuff !!
Lovely lookin boats :)
Actually, they are adjustable via a control in the cockpit, and are used to adjust the attitude of the hull while under way.
Sometimes they are used to lift the front in order to provide a better inlet angle at the pump inlet.
Sometimes downforce, sometimes lift....
Bad ass. Sounds awesome.
it's not that simple. There are no drivelines made for old helicopter engines in boats, so you do what you can. These boats use driveline hardware designed for 1000Hp V8s. So putting more than that through the system can cause things to break.
Making power is not a problem... getting it to the water and turning it into speed is tricky.
Exactly....I was taking note of the Gear Box to the jet drive made by the same company that makes V drive gear boxes.
Interesting, I was involved in water ski racing here in Australia for over ten years and for the Unlimited class to produce engines to be able to get to 1250+HP took a great deal of Money and effort.
The Ski Race boats today are powered to 1500-1600 Hp with stern drives and are lucky to acheive 130MPH with rebuilds only after a few hours.
Thanks for responding Mate.
super nice as usual Jay . no competition last year so you made your own! do you think the other teams would have upgraded to turbine power this? best wishes for this year season ,godspeed .
Very, Very Cool! Thanks!
...As far as you know...
?
You don't see the point ?
No, in the unlimited class, they walk all over piston engines.
You guess?
Tell you what: have a look at EngineBlockTV... on RUclips. Check out any of their segments on the NZ Jet Boat Marathon, and compare the piston boats to the Gas turbine powered ones.
How do you tell in the aerial shots? The turbine boats are always in front.
You would notice some lag on a motorcycle or a car, but Turbines work great in boats.
You know you have some serious power when you have a 12 inch exhaust pipe
just the intake grate in the water!!! awesome!!!
I grew up around a 90 mph jet boat but wow is this thing obviously godlike.
These boats race on rivers. Racing is racing, not just going fast, but as fast as possible...
Yes, they can wipeout, and sometimes end up on shore, upside down. The roll cage helps in those situations.
Awesome video Jay! I come from industrial side of turbines, and was just curious if vibration monitors are bypassed on a rig like this? Or are any used at all? Thanks. Couldnt find info anywhere on the matter.
Holy F.U.C.K! When that throttle was first floored I was instantly transported to my happy place, I envy all you lucky bastards who get to drive that sweetheart, thank you for posting this awesome video!!!
Beautiful. Dammit now I gotta go have one built cause I want one now.
Straight up beast
Hello! Great video! I was wondering what diameter the jet pump is on these boats? Thanks !
Hey jay awesome video! When you work on an engine that is going to be used for a ground/industrial installation, is there a price difference in parts? I'm asking because a friend of mine was telling me I could get a small turbo jet engine for cheep (ie, $5000) because the engine was a ground based unit, so all the liability concerns, with aviation engines does not exist.
dear AgentJayZ thank you for your reply
and your great videos.....
love the front wing lol
Miss GEICO used a fuel combination of diesel, jet-A and 93 octane gasoline. What do you use?
that is crazy how little of the boat is in the water.
The T58 used in the Seasprite helicopter has a two-stage power turbine, air cooled nozzles and blades in the gas generator turbine, and other mods to help it produce over 1800 reliable Hp.
Yes, everybody wants one of those.
To run a race boat, a quick checkup every few hundred hours.
If you inject water before the turbine wouldnt that give a much cooler egt and less stress and more power?
Water isnt scarse where it runs as in the air.
HOLY MOLY those things are flippinh nuts!
Over 200KPH on water,,, wow, just wow
The exhaust is at the back, and this isn't really a v-drive. The T58 would be very happy to turn a stern drive.
I like that sound of start up, Do you have to let the engine cool down after a run before shut down, I'am just a long time fan of yours. Thanks Jay, Your Friend in Georga USA. Be Safe.
crazy very crazy would love a ride in one of these beasts
wonder how many gs they pull when they open them right up
Wow, just wow! I never knew there were such boats! Being a Kiwi, I'm a Jet boat fan, but I never knew there were jet turbine powered jet boats! It's insanity, of the very best kind. In my utter ignorance of the tech involved I have but one comment; the 'contact patch' for lack of better description where the impeller draws the water in looks marginal when running the boats (especially the last one) at high speed. Does this not cause some cavitation in the output? Could the boats not do with a little rearward downforce to ensure the intake has more stable contact with the water? They are literally flying across the water! Thanks for the awesome vids!

Some of the boats have rear wings, and all of them use the front canards to set hull angle for best water inlet angle.
NZ is a big destination for jet boat racing.
Have you seen my series of 8 vids about the 2013 World Marathon on the South Island?
I've not seen the rear winged boats as yet, but had noticed the front canards. The boats would be able to do much speed without them, I suspect! I'll look up your vids on the 2013 World Marathon. I'm from Wellington, but had relatives in the South Island, so saw much of it. It's a great place to grow up, but I now live in the UK/Europe which has far more to offer, in all aspects. Thanks for the reply and Merry Christmas.
Nice video! This is using the Turbojet with a Power Turbine connected the the Screw Drive, correct? Though I wonder, wouldn't make it the boat go faster when it's using the Turbojet's engine thrust?
The speed is measured with GPS, and acceleration has not been recorded.
Both boats did a touch over 125 mph in this video.
Doea this boat has 1:1 ratio output?
The power turbine is designed to run a rotor. Gues at high speed using a higher gear could be faster because of the excess power. What do you think?
Hi, it is a nice test fro these engines. How gast did they go? Once tried to get an engine in Calif. and they wanted $70,000.00 it was used and had no log. Thanks for sharing your videos.
Hi, there is like a spark nois when starting the engines. Am I correct
I've ripped the sleeve off of two shirts walking by it in the shop.
Wow, wicked cool. This may be a dumb question but what good does a roll cage do on the water? That there in case you run aground?
28VDC motor driving the main shaft directly via a one way clutch
Nice boat
What is that "wha wha" noise at about 3 min? Is that noise coming from the jet pump inlet maybe? I don't hear it after the boat passed. At about 7 min Another Disaster sounds like one of the fighters from Star Wars. That's an awesome sound for anything that moves. Makes it sound like it is going really fast, but maybe not absolutely as fast as it could go.
I like the video!!!
I know what I want next xmas.
Yes Miss GEICO Racing had problems with saltwater ingestion. They solved it with a huge intake filter and never had ingestion after that.
How and what over rev protection if any is required like for example if the water intake comes out of the water and the load comes off the engine?
Hi Jay,
I am obsessed with this project great job.
I would be interested in both yours and Gords feed back on how the T58 would perform in a stern drive set up, not a V drive, personally I'd prefer the exhaust at the back ;-)
This is of course a propeller driven det up not Jet. 140MPH with a jet I would love to think how well a stern drive prop boat would go.
Keep up with the videos mate...FANTASTIC!
regards,
Grant
this might be a really silly question but could'nt you mount the turbine higher so you could add an afterburner for extra straightline speed or is that against the rules?
what did you study for getting this type of cool jet making job
Or just refer him to the race footage from a few months ago where the turbine clearly was dominant. Another great video Jay!
Thanks.
Salt spray is bad, both for deposits that destroy aerodynamic blade profiles, and because it can really cause corrosion.
The ships using large gas turbine engines have huge amounts of volume devoted to inlet purification. Removing dust, and mainly salt spray. Also the marine engines have extensive use of protective coatings and paints.
Race boats, like racing vehicles of any kind, lead a tough life, and are very maintenance intensive... or they don't finish.
Are the canards preset or are they adjustable while in flight so to speak by gyros maybe?
Do those use a propeller or impeller like a jet ski?
