- Episode 163 of Mike Finnegan's show, Finnegan's Garage, is for ladies and every gentleman who enjoys a good time. We decided to mod a 1976 Rogers Bonneville TR jet boat solely to make it shoot the biggest stream of water ever from its jet drive. The problem was that a huge thunderstorm swept across our lake during our adventure. With limited time to test our our new mods, we braved the elements anyway so that we could bring you this video! The mods made our boat slower but looks cooler when we shoot a massive rooster tail of water and we and can always undo our mod if we decide to go racing again. Check it out.

This is freaking awesome.....!!!!!
I agree!!
Hi kev
Not as Awesome as KSR!!!
So when is Kevin build a jet boat? Then Cleet will need a proper boat, then the boosted boat will come....
We need a ksr jet boat build soon? 😂
All the dislikes are Freiburger’s burner accounts
Im not much of a a boatman, so i dont watch any boat videos on yt (except the Cleetus ones). However, the fact that you explain this makes it much more interesting to know what youre doing and why. Keep it up and ill always watch and like
thanks, homie.
You can almost think of this like an upside down WW2 smoke screen from planes. Obviously the how is different. But the end result is similar.
I always felt Finnegan was pretty smart regarding cars and hot rods… his boat knowledge is on another level though…
The so cal fast jet boat scene is a ton of fun. Going out to the lower colorado river is like boating in a classic car show with all the big chrome and blown engines. The tunnel ram'd LS looks really good in that old Roger's
@@pw383426 Are they all selling cocaine or doing shady real estate deals like the cigar boat scene in Florida?
@@CIARUNSITE of course
@@CIARUNSITE its cali, so it's mostly weed. They always talk about Hydro's.... not like a drag or circle hydro boat... more like hydroponics growing dat green
Thanks to that episode on faster with Finnegan where that same boat couldn't hold up on the water! Seems it sparked something in him hahah! Dudes a genius his bud from roadkill is also as crazy and smart! If if not mistaken that was his cousins boat he bought it from.
I need a “No thrust without suction” T-shirt 😂😂😂
😂😂 I'm going to use that line on my gf tonight and see how that goes...
With a pic of the Renegade throwing the 40' high roost! Lol
@@rpmspeedlab993 keep us posted.
I would buy a shirt with that on it. Come on fin do it.
@@rpmspeedlab993 good luck!
"Biggest Roost Ever"
Cleetus: And I took that personally.
Underrated comment
Basically the roost is just a water burnout. Looks cool, but you don't go fast.
Save rubber, throw water!
That should be an FSM shirt.
“Save Rubber throw Water”
With a picture of a jet boat.
@@MrHatchbody I really like that idea!
Definitely would buy and wear.
You can't go fast in a pump boat anyway , any ANY V drive worth it's salt will walk all over that vacuum cleaner
@@hydroy1 But this video is all about the "burnouts"?
Save rubber, throw water!
@@hydroy1 Different applications. You can’t run that V-drive in shallows, mini jet boats running on rivers and streams is a blast. You should try it and you would be a fan of both driving methods.
Total awesomeness and all smiles watching this! I always watched the jet boats where I lived as a kid (some were direct V-Drive); finally scored a jet-ski in my teens and loved crossing their roosts as I fell behind and couldn't keep up. I have yet to own a boat, but if I get one, it will be a jet boat for sure, just to live my dreams out.
“For science, for you guys”
I see you get absolutely no pleasure from this endeavour. Purely doing it as a service to society
Not just because chicks dig it...haha
we're on a mission from god.

You’re my hero!

*salutes*
With your luck of boat testing & rain, I know a lot of farmers out west that would pay you a significant fee to start testing all throughout the country!
Thanks guys. All this boat stuff is making me want one. Might as well be a hot rod boat to work on too
So your saying Rooster tails are the ultimate in boat peacocking
No. 'you're'. And why did you capitalize rooster??
Ohh no 😟 the grammar police is here 😟😟
Dork Spray.
Wonder when James from the Cleatus gang will bring his jet boat up there and have a outing with them?
Was just thinking about how long before KSR tunes James' boat and he heads to GA with it.
I doubt James will have a boat left after the driving portion of the contest.
Maybe when he gets it running right and is not sucking water through the combustion chamber LOL!
@@79tazman yeah I'm not sure he really needs the water injected into the exhaust, that's very old school. Pretty sure none of Finnegan's boats do that.
We know James now, he's a racer and I doubt he'll race anything unless there's at least a chance of winning 😊
I wanted to see him give a carwash on the overpass
Wow, at that angle it is pushing the back of the boat Down!
Yeah it could sink quickly
Finnegan: “Don’t wanna run your jet drive dry”
James Taal: starts boat at the top of boat ramp.
😂 should’ve put this video out before cleetus started the boat challenge.
You read my mind right there.
"Dang rogue rocks are confusing as airplane chocks." (sry James, had to, lol.)
James has many more concerns with his boat than running his jet drive dry.
@@nunyabinis “still budget left”
there's a clutch between jet and drive shaft... he disengaged it to start the motor.
I love it!! Maybe add a couple hydraulic planners to the rear to keep it from cavitating when you get into it, one on each side.
Now it can be used as a firefighting boat.
HAH, Just blow the ski dock clean of the posers and install your own tribe.
There's a video here of a guy helping put out bush fires with his roost, it's great.
Kinda like 'ROLLIN' COAL' except yer 'WHIPIN' WATER'!! I LOVE IT!!
"There is suction drawing water and the jet pushes the boat through the water. I say that without suction, the boat wouldn't move, so it suck the boat through the water." -- mike finnegan.
"I didn't think it was possible, but this sucks and blows at the same time!" -- bart simpson.
Suction by ass, it's atmospheric pressure that moves the water into the pump!
@@rondye9398:
Not really, unless you're assuming the atmospheric pressure on the whole lake is what's pushing water into the jet pump.
What that system really is, is a ducted, shrouded propeller whose water stream is enclosed, rather than simply exposed to the water in the lake.
The forward moving force is the result of Newton's Third Law of Motion as applied to water. Specifically, if you take in a lot of the stuff in a short amount of time and pump it out at high velocity, you get a jet force.
Finnegan's contention is that because the jet pump (an impeller or ducted propeller, if you wish) is drawing water in, then it is that "suction" that is "sucking" the boat through the water. But that's like saying a jet engine "sucks" itself through the air.
That may work for a "ducted fan" -- which is the "bypass" stage of large jet engines -- or a multi-blade propeller inside a shroud, but ultimately what moves a jet-driven vehicle of any sort is the reaction of throwing a large volume of fluid out the back.
*That's SOOO my childhood at the RIVER with the Berkley in SoCAL!!!!*
Newbern should race jackstand jimmy with this.
Lol Renegade would stomp that boat in it's current condition.
@@bepbep7418 yeah it wouldn’t be close
@@bepbep7418 Jackstands boat would be pretty cool if they took their time to right all the wrongs with the engine and took it somewhere to someone that knows what they are doing to fix all the fiberglass fuckery going on in the the rear end.
@@TheBignick243 After they finish the 2500 challenges, I think do another. All three boats get another 2500 to mod what they have and repeat the challenge. BTW, jackstand would dominate at that point, right?
I've never been much of a boat guy until watching this jet boat stuff. Between you and Cleetus, I'm thinking jet boat demand might approach the height of your newly found roost. It's never going to quit raining 'til you guys quit running that boat. Good thing the water level is up.
Wow what a video! What an intro! Finnegan these vids keep getting better and better!
Thanks for watching!
@Finnegan's Garage, Am I the first person to notice that you turned the hat around on the carby's, to stop the rain being sucked into filters n engine. Don't know why but it made me happy when I seen that.
Thank you for brightening up my Sunday with that Rooster-Booster 9000'd jet boat!
Thanks for watching!
You guys and this Atlanta weather is hilarious.
That was so sick! Next week, put Finnegan behind the boat on a slalom ski~ *"C'mon, cut across the wake!"*
That was probably the best episode yet
If anyone on the lake has a fire get out of hand or a boat fire just needs you guys nearby! Nice work
Finnegan's enthusiasm for anything watercraft is always the best part!
Mr Finnegan is the type of man that knows how to have real fun 🙌👍
"For science" 🤣 love the Sunday realeses! Makes for a great way to start Sunday morning. You guys are awsome!
If I had a LS powered jet boat I would definitely build a set of headers with a 8 into 1 collector. The look and sound would turn anyone into a LEGAND.
Twelve-Volt Dave is literally the best! On a scale one 1-10… 12 😂
building a jetboat with my 1978 15' Baja can't wait!
Yup sensible. Nice explanation of how to impress the ladies with a Rooster Tail🧐Science👍🏾
That's definitely worth a thumbs up!!
Go Big D! While you're explaining the jet drive I'm thinking about Nitromethane Top Fuel boats. You can see the driveline torque load. I can see the boat shift with every little change in water flow. As if the water resistance has no effect. The boat shifts back and forth until the driveline load balances out. You see the same thing in 700hp Yamaha drag sleds. I still don't comprehend the belt takes the torque in those.
Anyway back to insane real Hemi jet boat action. We only got 76 out of modded twin BBC Donzi so that thing is flying.
What’s with this BS that “the jet boat is pulling itself through the water”. There is a suction force present and necessary for the jet drive to function, but the resulting negative pressure present at the inlet is distributed equally in all directions. Water is pulled from the front, sides, rear and bottom. Any directional motion resulting from the water rush in to equalize the pressure at the inlet is the result of flow resistance. There is some miniscule directional bias naturally inherent to the system which results in some forward bias, but saying the boat is being pulled through the waters is akin to saying that because a drag strip has a slightly negative grade that gravity is pulling the dragster forward, while technically true, in the context of how the dragster is propelled forward, the contribution of gravity is infinitesimal and a valueless statement.
Mike is not an engineer, much less a physicist :-D
After a quick read on waterjets, I would say the system is pushing, due to the waterjet creating "thrust". But, I think the question of push or pull has more to do with the placement on the vehicle. If the engine and waterjet were mounted on an extended arm in front of the boat, it could be described as pulling. But mounted anywhere on the boat itself is still pushing. Or is it if the waterjet were on the front of the boat? If I tow your car with a rope, that's pulling. If I pull up behind you and push, that's obviously pushing.
I think Mike is just trash talking for humor value, but it's a fun thought experiment. Is a front wheel drive automobile pushing or pulling the car forward? Would forward being pulling and reverse be pushing?
In a front engine car with rear wheel drive, everything in the drivetrain is pushing, all the way to the axle/s...if it's a manual transmission. But what about an automatic? A torque converter could arguably be pulling. When the engine side spins up, the other side follows, spinning the drive shaft, etc. Once it's spun up, I think it probably reaches an equilibrium of push/pull, since it starts to behave as one unit. But on spin up, the back half of the torque converter is definitely following, which implies it's being dragged along, which is obviously more pulling than pushing.
If you take a high pressure water hose and drop it, it will turn into a wild snake and start spraying water all over the place. Is the water pressure pushing the hose around, or is the hose being pulled up the water column? Or is it both? (Newton's 3rd law)
@@strangersound You need to go back to grade 10 physics and this time pay attention.....
@@strangersound how many hits did you take on the pipe before you wrote this?
Dude you make my damn head hurt
That was awesome! Would love to know what a datalog of a pressure sensor mounted past the pump would look like in general, plus any difference between the nozzle positions. Would internal pump pressure be increased from shooting the jet outlet more into the water VS the air, like putting more load on a turbo car or different loads on a torque converter.
no
Now make it so that all of the water jet goes out of the water. That would show how much of the forward motion is gemerated by the jet and how much is just the water being pumped trough the impeller. Also it would shoot a monster rooster tail!
Thats a perfect fire extinguisher.
You two are always my TH-cam highlight of the week. Completely certifiable! Love what you guys are doing. Thank you!
Love the Boats , There's a Race waiting for you down here in Florida with Jack Stand..
I would totally buy a “Captain In-Sane-0” T-shirt
How much downward thrust on the outdrive can the transom handle?
Since it is using the transom as a fulcrum I wonder if there is danger
Another badass episode 🤣 Newberns face during the thunder.
We have ran both a rooster booster with diverter and droop with diverter but never at the same time 🤣 actually seems like we get a bit more with the droop set up!
May have to revisit the rooster booster!
Love your content. I just wished you had more. Looking forward to seeing the caddy make its maiden voyage.
You guys are BADASS Love The Videos and I'm digging the merchandise 👍👍👍👍👍
Would love to see on a full sun day and what a rainbow affect that will make.
It always comes down to, "Chicks dig it" !!!!!
You guys are my heroes! High five to whoever picks the music.
I used to see somthing like that in the 70's on Lake Pontchartrain off of the New Orleans lake front. Now I have an outboard that runs fastest when I peg the throttle and give it all the trim its got to get max speed (plus a big rooster tail)
Imagine gunning it from the dock? Everyone would get sprayed! Even looked like it had a double Rooster tail a couple times! Hell Yeah Brother!
Thats so unpractical its hilarious, i love it.
"Relatively safe." Love it.
Best video yet guys!
Dave looked like a bobble head in the beginning of the video.
Do a video explaining water flow, routing, sizes of line, pressure and why. Advantage of co2 divertor over cable and why? When you should have co2 or cable for us idiots with jet boats. Do different hulls require different angles etc.
This is prime "Ain't care" right here... Love it!
Awesome video , can't believe how big of a rooster tail you guy's made
Looks like Dave is over his "jitters" :) That looked cool!
Investing in crypto now should be in every wise individuals list, in some months time you'll be ecstatic with the decision you made today.
Crypto is the new gold
@Big bobby J That won't bother you if you trade with a professional like Mr Gregory Manure
I heard that his strategies are really good
@@samanthavivian3916 Yeah, My first investment with Mr Gregory Manure earned me profit of over $25,530 US dollars, and ever since then he has been delivering
I got sir Gregory Manure info, how good is he ?
LIKE just for that crazy long thunder
For scriance!!!! Stoked she didnt flip over!!!! Stay safe and take care everyone
The renegade super soaker 1000. Chicks dig it lol
Pure happiness 😊
Awesome... if I was a betting man I would guess the drone got taken out in that very last shot?!! 😮😞
A rooster booster and a droop snoop? I thought I was listening to a foreign language there for a minute
Newburns boat versus jackstands would be a good time. Once james' boat gets tuned up right.
Def the neatest and most pointless thing I've seen in weeks, and I watch me some Cleetus!
45 degrees is probably the maximum effective angle... That said, you can tie it to the dock with a rope and use it as a fire engine.
God: makes it rain
Newburn and Mike: "We can help!"
water cavitates at 14.7 psi, Limiting its "pulling" capacity significantly. While Water is not compressible.... LOL Seems like a realy complicated way to say YOUR BOAT SUCKS
I need a jet boat to pull behind the El Camino!
Oxygenating the water, Love it!
Imparting work to the water is what moves the boat.
You accelerate the water backwards, all physical reactions being equally and opposite, you therefore accelerate the boat forward.
If the suction moves the boat forward more than the nozzle then how does the T nozzle on game over keep the boat stationary while you build boost?
Awesome!
It costs money, it's dangerous, and it makes it slower? So why do it? Cause it looks COOL!
Hydraulic steering would make a huge difference in handle ability. I'd definitely do that and put longer tilt piston on it so you could use it in race mode and Roost mode simply by adding a bump stop on top for race.
Rooster tails are the equivalent of truck nuts
Awesome rooster, How many hats doe's David Newbern lose when driving. Love the Channel Mike.
Ive built same system on my base model spark, with a lev el action. not as big as yours, but its pretty big to be only 900cc 112 hp. 30 meters or so, 8 meters high.
The renegade is a bad ass boat
Tim Place used to be in La Habra, Ca don't know anymore. He is a great guy to work with. He really knows his stuff.
nice day for a roost hey bud
If you carry your reaction mass with you, aka a rocket. You have thrust without suction. On a jet boat though, you’re correct.
You guys are just having way too much fun... Jealous.
wow weird how when the water shoots up the boat just about flips, idk how the suction isnt holding it in the water
Without a solid propellant like a rocket motor, you have to create a pressure differential to have thrust. So yes Mike, she must suck to move forward.
thunder over the lake? i've got a jet boat - let's go throw fifty foot high rooster tails into the air. Zeus: that guy gets a pass, freaking awesome! :-)
Fin your the man
On the next episode of Finnegans garage… We jack up our trucks, put ladder bars on them and straight pipes!
The only thing holding that boat to the water at full roost was suction lol
This was so much fun to watch. Great video =]
Macke a new bracket for the cylinder that you can completely change the angle. more.... lol
In the melody of Alice In Chains - YEAH THEY'VE COME TO THROW SOME ROOSTERS AH YEAH! 😂
