I used to have one exactly like it except mine had a 35hp Rotax. Having to deal with prop pitch myself I can tell regardless of what the tach says you still don't have enough pitch on the blades. It should lift higher even at half throttle unless there is a issue with the airflow through the bags. They can be a pain to get set right. I got mine to run about 45mph after set to what worked best. Also there shouldn't be water coming into the boat, mine came with a plug already in it. Good luck getting it going! It still has potential!
I'm kinda shocked that you guys didn't address the damage to the underside, that damage certainly isn't helping getting airflow into the skirt, which is the proper name for the rubber part
My buddy and I tried to build a hovercraft after an episode on Monster garage. With 2 lawnmower motors, bolted up with radiator fans to fill the skirt we could hover, but we never acquired a motor that could push us forward. We were in high school and our budget was like 80 bucks.

Hey guys, we just did the EXACT same reno on the EXACT same Scat I. My kid and I did a complete rebuild including skirts, new piston in the motor, scaled the head clean, complete carb, new blades, new pulleys, new belt, and some other fiddly bits. You’re close to getting her where she needs to be. Pull the top end and have a look at the piston, you’re probably losing power/compression there. Exhaust is next. We have the factory pipe, and sounds different than yours. Blade angles from the guy you takes to at the depot are spot on, we used his chart. A little more horsepower and you’re flying, I can assure you. Ours was rattier and had ‘glass work needs. She rips with the kid in it and it flies well when I’m in it too. Shoot me a line if you want to talk tactics.
BE CAREFUL!!!!! Hovercrafts are VERY VERY dangerous when they work right. They take knowing how to properly pilot one to not flip it and kill yourself. I'm so serious when i say if you get this thing running right, take the time to learn how to properly ride one of these and then when you do still be careful and wear a helmet and neck brace.
It doesn't need much power to get moving. My guess is the skirt is damaged and it's leaking lots of air. You can see on one side that had a major blowout. You can push a properly inflated skirt with your pinky and it will get moving.
More oil in the gas means less gas going through the carb jets witch in turn creates a leaner air fuel mixture. It would produce more power with a 50 to 1 oil mix. With todays 2 stroke oils we do not need to have so much oil.@@Barrymckociner074
@@Barrymckociner074 nope, sorry... The air stays the same. The oil and gas are mixed, so 40 parts gas to one part oil vs 50 parts gas to 1 part oil. 50:1 is more gas thus a richer ratio.
My buddy Al had this model and color brand new. He used to drive it 30 miles on the Susquehanna River to a drive up ice cream stand…..and drive it up into the parking lot to get curb service…….it was always drawing a huge crowd …✌️
This is better than my one and only hovercraft experience. A customer brought one in to the auto repair shop I worked at and I drew the short straw. Twice Ike mentioned "a runaway"...well it can happen. The first time I brought the throttle up one of the blades broke and speared it's way into the fiberglass shroud. The rest of the blades collided with the first one and in about a nano-second blades we're flying everywhere. The engine went to a crazy rpm with no load. I was at the handlebars so I yanked the kill switch...didn't even slow down. I headed to the back (no engine cover or blade guard bad idea) I couldn't block the air so I ripped the coil wire off with my shop rag... didn't even slow it down. Really, plug wire off 10,000 RPM! Apparently there was sufficient carbon in the combustion chamber keep it lit. Only a few seconds of run time have occured but I was now attracting a crowd including the boss and another mechanic who was bleeding profusely from his forehead. The boss is screaming "shut it off"... I'm trying. I removed the air cleaner and finally covered the carb and it choked out. The bleeding guy explained that a blade hit the bottom of the hood he was working under knocking the prop rod off and the hood slammed on him. The only cool part of this story is how the boss handled this catastrophe. He called the customer yelling at him to get the POS out of here before it kills someone. This was circa 1989 ish.
Ditto on that one. Clear the tools and EVERYTHING out of the way. I live in desert,and when ours started it blew half a tool box of tools out the back! Then buried it all with a crap load of sand😂 Good times
They fitted one, just not sure if its one designed for that engine. I'm more worried that the skirt is damaged hence why it wont lift properly. It should be floating on cushion of air not flat on the ground like it is now. Skirt leak or damage on the hull.
22:34 not having the back pressure that it’s needing won’t ever let you achieve the RPMs you need to or the power it needs it back pressure needs the expansion chamber with a smaller exit pipe. There’s a reason two-stroke exhaust systems are made the way they are I can remember as a kid in the 80s ride around on my CR 80 and thinking it would be cool to have it louder so I took the header off and lost power. I couldn’t even get it to get into the power band.
The zip ties are important and you should always carry many spares. They are designed to break instead of ripping the bags open. Also, you should have at least 30 horse in the power band. We had a real problem on water because in order to turn while at speed was risky and the natural inclination is to come off the throttle, the results were not good and causes injury. We solved the problem with an oversized 4 stroke out of a 4 wheeler for much better throttle spectrum and a flap that could tune the air flow up or down... kinda like the trim on a boat. And if you are fearless then extend the rudder fins a couple of inches for sharper turning at full throttle. These are fun on water but extra fun on ice!
many of the race ones have another motor at the front, this one fills the bag, or some adjust the diverter behind the prop wider the opening the more lift, but i would put more angle on the prop, or fit a couple of leaf blowers as lift motors, once you get the lift these thing fly, just remember to turn about half mile before a corner.. sort of like drifting..
Years ago when I worked on boats for a living I got roped into working on one of those , even when I got everything "perfect" it really didn't do anything very fun , nothing but a noisy novelty .
Joe with the channel 2vintage got a hold of a hovercraft a lot like this one but I swear it had two engines on it. One for lift and the other for thrust. He was having some issues with it along with one of the skirts was torn so he's had it sitting in a field for months now. Parts are a pain for these types apparently.
This one is a Scat 1, Scat then redesigned to a Scat 2 and Scat 2 HP. When they folded Hovercraft Depot got the molds and tweaked them to create the Air Commander Hovercrafts, Joe has an Air Commander AC3. He has it for sale on Marketplace currently.
you were correct to lower the mixture slightly, you might even be able to go lower!!! Here's why, that craft pre-dates commercial synthetic 2 stroke oils. A lot of modern engines will have a ratio closer to 25:1 vs older engines at 60:1. Organic 2 stroke oils need a heavier mixture to provide the same lubrication as a modern synthetic. You still wanna watch EGT and re-jet to match your mixture for optimum performance. REMEMBER leaner oil ratio does not equal lean AFR. It equals a very rich combustion condition which will wash your engine and cause more damage. Happy Trails!
Engine upgrade and duct upgrade for more air at the bottom did you guys check the belts and pulley you might want to block off some of the holes bottom of skri to help more air in the bottom needs the body needs to be around inch or two off the ground it still a good video bryce
Definetly needs a chamber and a silencer on it.That might make it run a liitle better.Duh on me, I posted that before Ike talked about it.Put the cr500 motor on it....hard enough to start on the bike,on second thought maybe not.
You guys should try changing the pully's for the belt gear ratio get the fan rotation better at idle that way your not running the engine at full rpm all the time and you can have slight floatation at idle and more thrust in the higher rpm's
When you mix to much oil in the fuel you can actually melt a piston from leaning it out cuz the oil is taking space where fuel should be and cause the motor to run to lean becarfull with oil mixes
I have Craftsman 3.7 saw which is the same as Poulan 3700, one manual says 35:1 and the other says 50:1, tried both and found little difference, come to the conclusion that it just requires oil, and its a beast that make man outta ya running that saw for a full day.
YEP, exactly as it should be for the power produced by that engine. Its a balancing act between thrust and pressure, filling the hub with blades would likely make the whole thing worse. They need to get the engine running well and then adjust the pitches to allow the engine to make 6500rpms and no more, they then will be utilising all of the available HP from the engine.
Despite the current volatility in the stock market, there's still a world of opportunity out there! I've been reading up on Bloomberg and other finance media, and they've been sharing stories of people making incredible gains, like over 250k, in just a matter of weeks or a couple of months. It's like a wealth transfer happening right in front of our eyes
It's really hard to beat the market as a mere investor. It's just better if you invest with the help of a professional who understands the market dynamics better.
Honestly, I'm surprised that this mrs brenda leigh is mentioned here, came across a testimony about her from one of the beneficiaries on the CNBC news, she seems to be doing extremely well

Wise words 👏 let's hope they read it 😊

I absolutely loved this episode. Even if Issac was sinking. I was laughing my butt off! 😂
The best worst idea!
What else you gonna do with it
It’s a Rotax 277cc. 28hp @ 5500rpm
Cleetus McFarlane has one, he’s an awesome dude reach out to him for some questions. I’m sure he’d be happy to help some fellow TH-camrs
I liked hearing you say MORE POWER!!!!!! That Otta doit!!!!
Next logical step is a swap to a Yamaha triple.
More POWER!!! can't wait to see this thing fly.
BE CAREFUL!!!!! Hovercrafts are VERY VERY dangerous when they work right. They take knowing how to properly pilot one to not flip it and kill yourself. I'm so serious when i say if you get this thing running right, take the time to learn how to properly ride one of these and then when you do still be careful and wear a helmet and neck brace.
One thing to remember is that different shape expansion pipes effect rpm and where the peak power comes on.
It doesn't need much power to get moving. My guess is the skirt is damaged and it's leaking lots of air. You can see on one side that had a major blowout. You can push a properly inflated skirt with your pinky and it will get moving.
Issac needs the set up at his place all the flooding
Ike
Your hunch is correct. The blade pitch is your problem. Tinker with pitch till you get the RPM you desire. Good luck, guys!!
Y'all had this Old Man from Washington NC laughing a bunch 🤣🤣🤣. Hopefully y'all will bring it back with more power. Love You Guys 🛵🧔💝💝💝
Go to 50:1 mix .... more gas and less oil
More oil will make it run lean (fuel to air mix) and take away power and check the jetting
More oil means richer😂

In high school we had a hover craft with a 3-1/2 hp lawnmower engine and you leaned to steer it. You need a separate motor for lifting maybe
Well at least Ike has a rotax leaf blower for the yard now 😂
New cars and cameras quote, "Grab the stick and twist it"
The bag should fill up on idle
To quote Monty Python; "My hovercraft is full of eels!" :P
Snowmobile engine or the 670 drag rail engine. That og rotax was maxed out at conception
I'd say more power and get rid of that muffler that's probably blocking air flows well.
Now the blades need to be adjusted.
Maybe make fuel tanks like saddlebags. No! One trip around the pond
50:1 two stroke racing oil. Block the bottom potion of the fan leave the top upper fan for steering moving.
Man this thing is awesome and the look on Ikes face when he started to sink was priceless 😅lol
I believe its true that there is correct pitch angle for an engines top rpm - why this would be a difficult set it and forget it adjustment IDK
The excitement when you picked it up, like little kids at Christmas. Love it!
I'm just old enough to remember the 1st hovercraft being tested in the Solent, so loud but an awesome piece of engineering. 🇬🇧👍
That's not a scat hovercraft, that's a scattered one ! :P !
it needs a good sand down and a a couple coats of gel coat

Hello All'. Like the hovercraft. What crazy additions can be done? 3cyl. Snowmobile motor?
You guys definitely need to get this beast up and running properly! 👍👍
Don't forget, the more oil you mix the leaner the fuel🤔🤔🤔

Yes too much oil makes em lean
