Chainsaw Powered Thai Longtail Build, Part 2 

I have another video using this motor on an outboard lower setup as a surface drive if interested ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-SDBDYqu_1Mo.html

As a Kiwi living in thailand building a jetboat, this video made me chuckle

I remember that rain, tests things to the limits, but good things to sort, sleep easier next storm :)

Extreme pee cam!!!! hahaha epic!

Very cool project. Good to see that bending tree getting more work.

Nice and to the point! No fluff!

Fucing halarious the cam views, a steel bar heated and twisted,then shaped can make a good prop. Your video also cheered me up allot thanks .

well, that cheered me up, lol, always love your content and humor, with the new prop she should be a little flyer.

Very desperate to see your next video❤

Looks like fun! I’d actually go to a more aggressive pitch but much smaller diameter the prop you are using could cope with 5x the power the Stihl has! id try something closer to 80-90mm dia and 19-21p also if the blades leading edge is deeper it will give more traction and less lift

Only people that weld and work with metal can truly appreciate the thought and skill that goes into these builds!!!

Nice ahh slag hammer there...

it will be clearly insane if you test it with a 2t kart motor, but the actual work is already insane

Subscribed. Fun to watch. I might reduce the diameter of the propeller you have in small increments, way 15mm at a time, until the prop matches the motors output. Your lathe should make short work of this.

The fish will hear ya coming 😂

Strange question for ya Dan but did ya check the nylon bushing ya made down near the prop end? Check out RC boat drive shafts as it would give ya some ideas as the RC boats are ball ball bearing or bushings and packed full of grease as the nylon would get hot and start to melt due to friction

just a thought, when watching the Tai Longtails with v8 and huge props, they want the prop to cavitate, I would look into surface-piercing props.

Keep it cavitating its fine, once it bites its all over .

The prop doesn't seem to be adequately submerged

That pee cam was insane😂

man it was close to getting to plane but i knew from the get go its too aggressive of a prop

nice chipping hammer🤣

pretty awesome it runs really good just needs a different prop, an if it dont work ot try a 4 stroke like a 80cc predator pretty sure they have aftermarket parts for those to, then that outboard prop will work flawlessly.

I enjoyed pee Cam....was faf....

Best vid so far mate!! Brillliant! With regard to pee cam, I think you have a problem you should seek medical advise on! :0) With the 3 blade prop, could you just machine the blades a bit smaller or thinner to reduce the " gearing" / pitch?

You need to add the cooling ducting back to the engine, otherwise it will burn up real quick

How much do you want for the bending tree?

Mate, good job 👍 love your work. You got some good access to amazing tools too, pretty jealous. Bloody propellers 🤦‍♂️🤦‍♂️, it’s the most important piece sometimes. If your like me, you won’t give up, just another hurdle to jump, makes the wins even more impressive. Can’t wait to see what you come up with for the prop mate, unfortunately I haven’t seen a right hand mud prop. That 5hp prop is probably about a 8 pitch?? Wonder if you could back it off a bit by bending the leading edge up (block of hardwood with rounded end and a hammer) Just bend the leading edge up a little, it will reduce pitch, try to keep the blades as similar as possible. Leave the trailing edge alone for now. Also the stock alloy prop won’t be that great for surface piercing unfortunately unless it has a small cup added to the trailing edge which will add pitch 😢 I would try back it off and see what it does first. Thanks for your videos mate, awesome 👏 Cheers 🍻 Aussie Boat Guy 😎

Your channel is so underrated, great videos always.

Put a Bigger Rudder On it With Large Surface…. To Direct Water Better Will Steer Way Better Just a Suggestion I Like Your Videos Keep Them Coming Brother!!!!

It acts like what's called A outboard motor cradle. witch takes the place of A extra mounting pivoting point bracket is all it does. Just basically simplified easier version set-up.

Loved watching your channel and projects grow dude, awesome stuff

This is Awsome Love Your Content Where Are You From? I’m a Kiwi I Live in New Zealand Born & Breed 💯🦾🇳🇿🤙

It's like A rubber Muffler/mufkin bushing on vehicles like on newer model car for such.

Sounds so good, cant wait to see this thing zoom, 3D print and cast up a prop?

I had a similar idea but using a leaf blower or weed eater motor but they may not have enough power by the look of it

Yosun biçme makinesi olabilir .

Good job sawrus nice job 👍 👏 👌 🙌 💪 😀

I heard that Extreme peeing will be in the next X Games. Nice camera and editing work

Hahahaha so much for pissing into the wind!

As a Thai guy, I just saw 3 blade propeller longtail at the first time, Did it better then traditional 2 blade ?

Cracking up 🤣🤣🤣🤣 on the cam shots.

Seen you with your boat on the back of the ute today. I knew a video was coming

Props are tricky bro I built my mud prop out of bin crate plastic works good on the drill ,slow rpm but bogged on the lawn mower motor keep at it you’ll sort it out

I think your motor doesn't have the weight and torque to be able to drive your dinky dingy! Gas weedeater engines have the RPM, but not the brute muscle torque to spin an agressive prop. Some weight before the prop might help some, and brass bushings with crater grease might help more. Very nice idea, with much more development in order. Someday you might make money selling kits as used weeder engines are practically a dime a dozen right now. I have four from other garage sales that I bought for projects. None cost more than $10 each.

Skidoo motor would be crazy

That saw motor needs some port work done to free it up a bit especially exhaust....just a simple exhaust mod can wake a sae up nicely but the port work might have you grabbing for something to hang onto lol

An expansion chamber would keep it from stalling

Sweet😂

Your camera angles are slightly unusual :P It is nice things are slowly coming together, looking forward to the next video.

Steep learning curve

Bloody kiwi’s FAF

Pee cam tho, dead 🤣🤣

you need to put back the top cover on because chainsaw motors are cooled with the fan and with the cover its forcing the air thru the cylinder head to keep it cool

The pee cam! 😂🤣😂🤣

you could put the prop on the lathe and take 1\2" or so off its circumference so it would be less aggressive

Postal 2 "pee cam"

I could paddle dater than that. And all that time spent in the shop could of been better used drinking some beers. Cheers

you just chip the slag with a set of calipers lmfao?

I flinched at vernier chipping hammer, but not at tungsten falling to crock. Yikes

idk who tf u are but i just subbed...

Love the cams

See if you can fab a cooling shroud - aren't these forced draft air cooled engines?

this thing with the right prop could be cool

Awesome.

Be safe

Your boats too short and use a two blades race prop it needs speed to unload the motor👍

Ahh. Back to your old self again. Awesome entertainment. Ps, how did you go with the motors and drives? Any luck fixing them?

Hate to say it but those longtails need torque more than rpms.

Running the motor flat out might work along with wee cam on full.

Chipping slag with a digital caliper! Hahahaha brilliant!

a 2 bladed prop would lessen the load on the motor.....

You need a reduction gear set up and or a super shallow pitch. That engine doesn’t have the power to turn the prop you’ve got at 6000 rpm.

go to a old boat and see if you can get a feathering prop off a old sailboat .You can manually adjust the pitch etc

wonder if you could get a jet prop on the end of that ..?

pee cams rock (er, spray)

Replace smaller props would be better

To much mucking around for half a hp.

070 chinsaw engine so good

Needs a turbo 😁 looks fun...

rpm is too high for that prop. To make that prop work I may gear down the shaft rpm. A different commenter said smaller prop but I disagree, it looks like it can handle larger prop but at also geared down rpm.

Why is no one talking about the audio missing on this video?

No cowling =no cooling 😢

take apart a bad angle grinder to get 90 degree angle adapter

Great vid mate

212 preditor motor.

Drill camera is a winner! I can get dizzy and throw up with out leaving the couch. Normally I have to get up and spin myself around. Well done.

Nice to have a boat you can carry with one arm. Nice try with the long tail. A different prop might fix the problem. A bigger stronger shear pin is in order.

What Hp the chainsaw pushing?

3d print and cast a new prop !!! Love the build sir !

13000 rpm is too much for that prop
