wankel turbo ski race boat

[@r3sonate]

When a vid from April 2006 shows up in your recommended feed with a rotary race boat AND the effort added to include some music, you hit the like button.

[@jansurlykkeschack7955]

Awesome piece of engineering. This wankel sounds really sick

[@DMRH69]

Yes, its direct drive. Max rpm (9000) winds out to just over 200km/h. A feature story about it was done in ZOOM magaine (Australia) back in 2004.

[@PapiDoesIt]

This video started off well then was utterly ruined by the "music".

[@PimpMyPc89]

Pretty much

[@SPEEDTRIBESAKURA]

the music was like....3 seconds long...

[@ElevatedAgenda]

Kyoushuu Diecast 3 horrible seconds...

[@thatL33Tboi]

@@ElevatedAgenda ya but still, three secs?

[@Miless93]

@@SPEEDTRIBESAKURA Ikr snowflakes lol

[@icloudhenshaw38]

The sweet hum of 10,000 rpm aha

[@davejcarter]

that sound is beautiful. I have never seen rotor power behind a boat. cool idea

[@pleite567]

i can't stop listening to this baby, damn georges sound!!

[@SamanthaGibbons100]

chuck norris would be proud to sea biscuit behind this machine.

[@adamcauser7674]

Sam Gibbons i'd do it

[@leckmich0815a]

Sounds like a combustion and a jet engine at the same time! Fantastic :-)

[@CrossWindsPat]

OHH YES!!!! ROTARY FTW!!! NOTHING SOUNDS COOLER!!!

[@raymondregan5148]

yes German inventors could not get it to run properly sold it to Mazda-Japan & rest as they say is history

[@crazyhugs]

nice motor , love the sound of a turbo rotary

[@TOR1NO]

One of my favorite videos. Thanks for posting it.

[@DMRH69]

Built by Xtreme rotaries in MEL, VIC. they compete at the "Southern-80" classic each year & kick serious V8 supercharged arse. Had to keep going up through the catergories voluntarily as they where making lesser V8's (eg, blown 350 Chev's) look quite average. Now in the open class against blown Alchohol slurping 7lt big blocks (last i heard) & still managing to make it to the top end of the field. Not bad for a 2lt engine..........ha ha ha

[@hondadrvr3]

GOD..That turbo sounds amazing.

[@unsane]

Read all the comments. Somewhere in there the actual owner of this boat opined. Think he said 118 mph was max.

[@fatwang]

I love rotary engines, they seem to wind up forever. One thing though, you do have an issue with walk even though you do a masterful job of keeping up with it, someday that is going to bite you,hard. I'd put some extended trim tabs out there or change the V configuration to present a bit more flat across the stern. If you are out of the water except for your drive you may need to take some (depth)bite out but increase your thrust profile to go faster safer.A great craft at any estimate. WFO!

[@unsane]

I would have no idea. I found this vid on another website many years ago when KZbin was in its infancy. However, if you scan the comments from a while back, the owner of this boat commented on it. You can find his page from there and email him.

[@rnsaza]

the way that hull rolls from side to side at speed scares me even tho I'm not in the boat!!! Eeeek, no thanx! Motor is wicked!

[@unsane]

@Swansen03 I believe the owner stated that it was a 20b.

[@dietermg6339]

Just a historic anecdote: End of the 60s Wankel ventured into exploring marine motors for leisure boats. My parents had a sailboat (Mistrelle zeilboot, 9 meter, 3 ton, made by BOWA in Holland) that had one of the pre-series of this little marine wankel with one rotary piston. On behalf of Mr. Wankel the boat was trucked from Holland to a boat show in Friedrichshafen (Lake Constance) and back to Holland. Mr. Wankel came on board and discussed the engine with my father (engineer). I was there as a little boy and saw Mr. Wankel. Unfortunately they never were able to fix the cooling issues with water cooling. My parents went through 4 or 5 replacement motors and Wankel gave up and never produced this marine engine in production quantities. It was about 1/2 the weight of a comparable diesel with the same power output (I don't remember, 20 or 24 DIN PS) I'd love to know if there is anyone else who has more info concerning this marine Wankel. Greetings from Ohio

[@philr300]

Freakin' awesome! And the sound it makes is very "turbine". Fantastic work!

[@Travelbeatcreations.official]

This is so damn sweeeeet!!!! Rotary/wankel is known for their insanely high rev and some of those have a sound that are so whicked! Give meeee lol

[@TheADog]

Holy EFFF!!!! Haha liftoff, damn! I'd b wearin a helmet too...impressive

[@JamieKugelmann]

that noise is absolutely astounding

[@henry55430]

Jamie Kugelmann The boost building noise is orgasmic.

[@DMRH69]

Fastest boat I have ever ridden in. We did 175km/h on choppy Port Phillip bay (MEL-AUS) the accelleration was awesome, the sound was sexual. The experience was forever. This vid was on a nice flat lake, they should have hit redline at around 210km/h....

[@inokichi13]

Our bass boat did 82mph, that was STUPID! Couldn't imagine 105, let alone 118, very nice.

[@Blimp19986]

I love the sound of a turbo whistle

[@stretcher]

@philr300 Well, there's also a huge turbo hanging off the side of the rotary; look right behind the intake pod filter on the left of your screen.

[@walldoo99]

Imagine if you hit a wake at that speed. I was on a 750cc jet ski and hit a boat wake from the side while making a turn and that flipped me and the jet ski caught air. Hell of a ride and would have been a hell of a video if we'd had today's helmet camera back then.

[@shadesCAN]

chine walking at 105 no thanx, 1 wind gust or a little ditch wave can make you very sorry real fast with out any warning. Nice build tho , it hauls ass

[@codyking4848]

weeee, boy that chine walk at high speed made me very, very nervous

[@bloodreighn]

now that you got that Boat anchor int he middle of all that water, you can chuck it over board!

[@CrazyFunnyCats]

😂 when every fish 🐠 learned how to run! 👍👍👍

[@DopeKenFresh]

Get a 4 rotor :D

[@edgasket]

there's no intercooler cos it has a charge cooler... where better to use one too - plenty of cool water available :)

[@ixer76]

Insane. Completely insane.

[@Swansen03]

@rossiholland not to many rotaries out there. 13b, 20b, most made by mazda. so, thats a start at least.

[@katana1150]

actualy the rotary engine was invented by Felix Wankel born in Lahr Germany in 1902. the Japanese only perfected the rotary engine for mass production.

[@Pattysreal]

Happy little rotor-motor! Quite zippy lol.

[@BigEsGarage]

Now That's Boating!!! Freakin crazy ass.

[@THEFERMANATOR]

I always loved hearing a rotary when they would launch in drag cars. 13K+ would be hit by some of em. I don't know of many engines that can rev like a wankel.

[@truespyfan]

I believe Andrew at D&F Racing in Melbourne had something to do with this boat.

[@bryangreenleaf5001]

What is the difference between a hull like yours and a vintage-style water ski boat? I’m curious because I’ve got an ‘89 tournament water ski boat that I’d like to convert to more of a high speed vessel since I don’t ski anymore.

[@wolfen750]

Nice work. ok a few Q's is this an I/O setup or tru inboard and second wat boost presure are u runing also pitch of prop ? is the engine cooled like a pickup or is, inclosed loop cooled like some fresh kits are doing.

[@DesmoGabe]

Mamma mia che bestia! e come fischia quel turbo!!!

[@bigman95impala]

bananas man just crazy right there you have something different so how is fuel economy when not spooling/going 100 mph? it sounds clean and smooth throughout the rpm range good work buddy!

[@wolfen750]

I ask because i have a 17' checkmate vmate2 and i was looking for a light alternitive to a v8 conversion the top end hourses is wat im looking for so i was thinking of a 4 or 6 banger turbo have u seen this ??? or is it a new idea can i mount a 4 cylinder to an alpha 1 outdrive ? is this posible? thx for the vid. AWSOME WORK.

[@CBD-Life-South-Africa]

Would be interesting to install this in a old wooden yacht, pretty unsuspecting,

[@faster4tec]

That is a LUSH sound. I would like to see a lakeshore vid, see what she sounds like from a distnace, I bet it puts the fear of god into all within a good mile or two ;)

[@poz3idon]

YOUR FLYING MAN!!!!! so Cool!!!! Im wondering - why not make a sail boat with a cool wankel engine?! (one u can live on for free) Any ideas?

[@mrskyking737]

This is a gasoline Mazda, I assume? How many rotors? How much boost? What are the torque/HP numbers? What would it cost to build something like this?

[@someotherdude]

I heard the water skiers have to wear respirators to ski behind this boat. Is that really true?

[@guitarfreak2536]

wow nice boat it's fast and cool i want one

[@Ravenlord79]

yeah, right... if you lift 75kg weight 1 meter high in 1 second, that is one horsepower.... and 1.36HP is one KW, which is desirable unit to notify power.

[@kimkayken1]

Hi not shore if you can help me, 1980s in sydney , Americans came to ski race , and wished if I could see if there races still excites but i have no memory of any names .

[@geoBM818]

damn that thing sounds raw!

[@badfastbusa]

sick freaking boat!!!!!!!!!!!!!!!!!!!

[@shirleymae30]

I have several advanced concept, commercial/military, flying work boat designs, (that are NOT hovercraft, or air boats), and i am wondering if the output of that type of Wankel engine could possibly be geared to operate both a water propeller, and an air propeller, and be clutched so that they could run simultaneously, and independently ???. I've got to learn more about those types of engines.

[@skullfracture2]

Might bog down too much at low rpm under the type of load you described, even with a large gear reduction. The fuel consumption with rotary engines is atrocious. That’s why they aren’t produced commercially anymore.

[@pmgodfrey]

Must...buy...this...boat............

[@phunkycypresshill]

this dude built my motor extreme rotaries

[@jetraymond]

was this done by Pettit Racing? I know that he has one and I was trying to find it. I have three rx7s and he works on all of them.

[@bigman55434]

That is a bad ass boat.

[@dewpoint88]

good god! what a fantastic noise!

[@robh87]

that works surprisingly well. I always thought jet drives worked off of torque. apparently lots of rpms and turbo fueled hp gets the job done too. can't believe the top end that thing has you must be in the 120mph range yes?

[@unsane]

It's a V-drive, not a jet pump. The owner commented years ago, I think the boat could top out around 118 if I remember him correctly. People water ski behind these at those speeds. The sport is big in Australia.

[@phatkix]

Holy shitt! Rotary power.

[@pixuma]

oh my god..... chilling... flat out chilling!

[@jacobwebb8818]

waterski behind that thing? no thanks. I'd love the sound and experience, but not the hospital Bill lol

[@samuelhumphreys7712]

Assasinpiggles NHS can solve that

[@PikkuMiku]

That is just pure Awesomeness

[@mytube308]

OMG,,That thing ROCKS!!!ToP StuFF!!!

[@tspcobra]

Holy Crap, I don't think I would ski behind that boat.

[@veraysweet9624]

dayyyyum that turbo whistle is nuts! do you know what engine this is from or who makes them cos theirs no way thats from a mazda !!

[@DrivenMind]

That almost looks too terrifying to be fun...

[@brandino13]

unsane, does that beast run on a prop??

[@Mike-01234]

Little bit of chine walking that is scary at high speeds on a flat bottom boat.

[@macbookawesome17]

kell490 I think thats turbo noises

[@richo440]

Fucken awesome mate! Not sure i would ski behind it, but i would sure as hell like to go for a ride in it.

[@barrythacker7281]

will it pick me up on one ski? what is your destination i like going no where fast

[@RegularEducation]

Where can I buy one? Awesome video!

[@brianheiden6623]

Wow works great in a boat!

[@rotaryracing1982]

god damn that is nice ... whats it boost? gotta love the rotary engine.

[@onlyrotary1989]

YEAH BABY!!! Wet Wankel...Love it!

[@vonjager]

what a great ride! cool video!

[@unsane]

Scroll down the comments to find the comment from the owner of this boat. It is going 105 in this video but can go faster.

[@xlrationmarine]

Nic one. I've seen the world records set at firebird lake for single male, tandem and single women. The chick went about 100 mph last fall at the world finnals. Yea they speed ski.

[@rreidnauer]

118mph with a helmet on? Man, I ain't so sure I'd want to be wearing that without some sort of body harness with limiting straps to keep my head from being ripped off or neck snapped back when you hit the water.

[@sportsmansparadice42]

118 REALLY?? Dial 1 800 HOLY SHIT!!!

[@Rettirauven]

Holy crap that is cool!

[@rossor6ridr]

im thinking the impeller would explode at rotary rpm's!

[@kylej3021]

Next project for @robdahm

[@NonRider]

wonder if a pad would help on the hull.

[@r1wantone]

Wankel engines sound great

[@mechanertainment4562]

Well great, now I want one 😂

[@fab069]

LOL it's amazing! well done mate! :)

[@ViperSRTnACR]

Awesome vid! I grew up on a lake so I have alot of appreciation for cool builds like this. Is that a GT35R turbo?

[@IncineratorX2]

one word : NICE!

[@Twinturbo120]

good question

[@immuki]

hope you dont hit a log.... i ran over a buoy on our seadoo at 20, that was scary. cant imagine 100+

[@justinsue]

its it direct drive or has a transmission? how many revs you doing?

[@MistahElias]

THANKS!

[@01oelliott]

Holy shit, listen to the sound of that thing :D

[@gleno2008]

thats off its head man, what a rush, yer
