I love how you always shout out the small businesses that you get things from. I’m sure it really helps them out a ton and more people need to follow your lead
You should keep your prop speed below 3200 rpm. Anything above that causes the tip speed to exceed the sound barrier and create turbulence that decreases the efficiency by around 30% instantly, its also very unforgiving on the blades. If you exceed that limit under full load you need to re-pitch the prop to limit rpm and increase thrust. Exploding props are terrifying and can easily be deadly!!! Have fun and Stay safe fellas!
Diameter plays a significant roll in the equation. General rule is 3200 for a 76-78" prop. There are calculators to get exact numbers on most prop manufacturers web sites
Yup! My airboat tach was off when I bought it from the previous owner and the first time I tried to drive it, it over revved and snapped the prop and crankshaft off at 3500+ rpm on an o-520
Kyle and Wyatt you guys are absolutely killing it another well done project you said you would K swap the world and you are doing it. love you guys can't wait for the next one
From a old air boater, brother never put your drain plugs on the outside of the boat. Something can catch the ring and pull them out. Always on the inside. Ride safe.
@@X3R0D3D That's true for your typical airboat. That's why the driver is always up high to see crap coming that you don't want to hit, like tree stumps, and boulders. But this is far from a typical airboat
If you get a bunch of water In the boat you can pull the plug out as long as you are moving and it will drain out the water. It's really fun to do with non boat people they start freaking out thinking your going to sink the boat
I was having the shittiest morning ever. Just found out I had to work doubles until they find a replacement for the person who left my work. Took my lunchbreak & this video was uploaded for me to watch. I don't think you realize how much better this made my day. Being able to think about the water, & getting away, and the engineering you guys put into your stuff always makes me a happier person. You always knock it out of the park. I've been watching you guys since the hatchback days! You never fail to deliver! Thank you,
When you turn don’t let off like that mid turn things will get really tippy. If you get in trouble it’s best to give it gas and throttle out. Also a better airboat hull would help. Love that your making some airboat content!
Please make a video with JH Diesel with that Airboat! I want to see that colab and he is also a Airboat beast! He's also insane, I think you need that, LOL! Congrats on finishing Sick Week and also bringing back Emilio! So happy to see the BoostedBoiz back together.
For a brief period I lived about 4 hours north of Toronto, we were about 50 km from nearest town with a doctor. The Doctor had a seaplane from the 60's that was similar in deign to the Icon (pusher engine mounted above the wings) and would make house calls to those who lived remote with water access. He would fly in, do his exam and then go back out on the lake, open the nose hatches and go fishing. Once in a while he would take us up for a ride.
if you consider boostboiz classic something that works half a day and then needs 3 weeks of work cause they didn't do nothing right the first time, then it's definetely not too early.
I ran a very similar hull on an airboat we had but i relocated the seats and it made a huge different in the boat. i moved the driver's seat to the height of your switch panel then dropped the passenger seat far enough you could put your feet on the floor and it was a night and day difference with COG
Great build boiz like always killing it ...tps I getting blown by boost leak by throttle body shaft smoke tested and you find the leak ...drill a tiny hole at the base of tps between throttle body and tps and won't happen again .or get another throttle body...then get a fishing rod Springfield xd 45mm had gun and go fishing for gators ....fun times
You should put some springs on the rudder bar to have it center itself. Seems like it'd be a cheap and easy solution to provide a bit more stability and ease of use.
It actually looked better in the side view with 2 onboard, with just 1 it was always nose up and the stern digging, never tried to plane, with 2 much better trim angle, wanted to plane, ck your vids. Boats are a whole different beast. Good Boating. )
Those airboats are mad. it is a really unique and interesting culture. I will have to have a crack at making my own one day. The perfect thing for swamps.
I’m no expert, but I think the reason they put the steering cable lower is in case you’re going through brush or trees it doesn’t get caught in some branches. If you’re out in the middle of nowhere, that would be a hell of a thing to lose.
There are all kinds of clever things like that on various vehicles and machines. My old 42 Jeep the tie rod setup was in the front of the front axle so if you hit anything really hard underneath the front it was easy to damage the steering components right there. I also had a early 41 Power Wagon and all those parts ran behind and underneath the front axle. If you hit something the tie rod would just move and bounce out of the way because it was built to work and still be able to give if something ran into it. Also the front grill cage protected the headlights and radiator. The Jeep everything was set back behind the the stamped front grill so same thing. The old guys were more clever than folks realize about making things work and live in bad situations. Some things used to be built for function over form and routing that cable a certain way had a purpose just like the Jeep and Power Wagon I used to have.
@@wyattmartin534 Well I've seen it under various awd heavy duty trucks but the first place I noticed and had time to think about it was under my Dodge. It really is a good idea but maybe most light duty trucks they don't care or it's more complicated to build. The setup under the WW2 Jeeps seems pretty complicated and fragile but it worked and I never broke or bent mine that I'm aware of.
Gym Trainer reacts to K-swapped Airboat Kyle, chop chop. We're still waiting for you to get her reaction to the Jetboat, but we understand, sick week and all that jazz. Come on Kyle, do a solid for the boys. 😉👍
Dont have to worry about all the leaves and stuff on the cars anymore... Quick spin around the yrd on Ol'e Skippy and they will be someone elses problem 😂 If it feels more sketchy than it should, might be a good colab opportunity to get someone that knows how to build / setup an airboat that can test and advise on changes you could make to make it more stable.
If you're really concerned about the water, look at installing an auto-bailer. They allow water to drain out of the hull while going forward but will close down when stopped or backing. Also, life jackets.
I love it. You guys took what some would consider junk and constructed a really cool airboat. The turbo Honda is able to produce about the same torque and horsepower as a normally aspirated 4.8 LS while using a lot less fuel overall. Kyle and Wyatt might look into widening the hull, making it more stable and a bit less leaky.
I believe that the next time you load your air boat on a trailer, make sure to have a water hose spraying water on the trailer ramp. It'll reduce friction and drag. Just some advice from an old man that's done that before. 🤣🤣🤣🤣
Hey guys, get 2 smaller pontoons one for the left side and 1 for the right side. Mount them solid near the water line of the sides and that should fix your side to side worries on turning. Maybe 12" diameter pontoons or bigger. Or Balls to the wall and find your limitations! I'd carry a pistol for the alligators just in case!
4:10 Honestly. You could do so much with the equipment you've built when Storms hit Florida. I would definitely binge watch a series of you going around and driving that thing through flooded areas!
I love what you guys do. It's so cool to see it on the water finally. Glad you guys are having fun. Maybe a suggestion to help with the top weight. I've always wondered why you decided to have the motor so high up. I understand for simplicity. But if you can bring it down and then belt drive the fan blade it would really help. Also look to see if the angle of the blades can be adjusted slightly too. Maybe it needs a little. Size of pulleys can help with ratio of blade turns.. can maybe get more out out of it with the belt. But still amazing to see it working.
Seems like you need to hit backwaters of the river, the shallows and get a feel for ol Skippy, braver than I taking it out on open water for a maiden voyage. Airboat ripping is the highlight of my trips to visit my family in Florida. Some of those dudes are runnin 800hp supercharged LSX powered beasts that scare the hell out of me but I love it.
Coming from a long generation of Florida men you’re half way there. You got the airboat now all you need is a buggy and you’ll be inducted into true Florida man form
Please build razzle dazzle!!!! Was some of the best content on this channel, rode some wheelies with brent , craped your pants and haven't seen it since.
Two quick observations guys. You have to consider your weight distribution. You have a lot of weight on the back have of the hull, add the captain and you start getting the pendulum effect. Got to move it around, like moving the fuel cell and battery. Maybe moving the captain to the front. Also, I think you running a gear box, like a 2 to 1? That allows you to turn the motor at a max of 6,000 RPMs while keeping the prop at 3,000 RPMs Anything above 3,000 RPMs the prop reaches what known as the critical point of departure. In other words, you props can simply fragment. Also you have to insure you air push is correct. This is done by raising and lowering the back of the motor, never allowing you prop to go lower then 4 inch’s below the transom. I really like the Honda motor idea. I’m not sure at what RPMs that motor turns the HP on at. But keep that prop no more then 3,000 RPMs. As a safety note, never walk behind the boat when the blades are turning. A simple washer or any object that gets in the prop becomes a bullet as it’s slung out the back. And that prop will suck every loose item into it. Stay safe and ride.
i have several friends with turbo ls airboats. most put the intercooler in front of the radiator. a couple have it up there and have no problems. the main thing you guys need to do is trim you crankshaft angle and prop angle. the prop could use more angle to keep the tip speed lower and give you more thrust. and you need to adjust the crank angle so that it doesn't push down on the front as much.
