What a sweet little creek. Looks like around 30mph. Bloody hard to control a jet boat in narrow conditions when your instinct says back off the throttle in a corner.

Excellent work Dude... I was ducking at every low bridge!!

I think you're doing really well.

The engine pulls the chain your tensioner should be on the push side of the chain

Enjoyed the video. Nice run up and down the creek.

Thanks making another jet boat with 212cc engine, video coming soon

Ok. Just found this video. Super cool ride. Reminds me of when I had one of the Briggs & Stratton 5hp 4 stroke outboards they used to sell. It barely moved my boat and people would hear me coming long before I got there. They would be standing on their docks because it sounded just like a lawnmower engine except it was a boat motor. Every one of em said we didnt know what was going on.

$80 for a quickie $120 for a whole half an hour but the memories last forever.... !!! 😮

Pretty cool man, i've always loved this idea. No need for that clutch really, ditching it gains you the advantage of a slow troll all while getting rid of a failure point. Cheers

Belt drive, with slip roller tensioner

That creek looks like it be a trapping gold mine! Also that jet drive Jhon boat is awesome man! One day id like to build one myself! However im gonna use a snowmobile engine or a 600cc 4 cylinder crotch rocket engine i personally like a lot more power! But hey thats just me! The predator engine is awesome too just not enough top end!

Pretty impressive!

You have a pretty interesting installation, and you’re learning by doing. Great stuff! With all them very low bridges your going under I myself am not sure I want to go much faster on that creek than your going right now. Looks like you’re having some good time fun in some pretty skinny water.

Having Lots of fun learning

Your chain appears to be too tight. I'm eating dinner while watching this video, ducking and weaving at every tree limb and bridge. Nice build concept.

I have a jet sky Kawasaki 755 engine, I already put one of these on but I can't increase the rotation of the turbine I put on a 100 cc motorcycle crown I haven't tested it yet and it's very difficult congratulations

You should take that engine off and use a 2 or 3 cylinder liquid cooled snowmobile engine with the jack shaft/clutch setup. You could utilize the water you’re running on to cool the engine. Also you would see rpm’s a lot closer to 8k or so depending on what gears you used. Cool project though. Look like fun.

Gotta use a 340 enticer motor! Bulletproof aye! Send it!

this is bad ass dude

Cool! I don't know why but I kept duckin when you went under the bridges... 😅

I like the idea of using the predator motors.. I think you need to put on a comet style torque converter and then run a chain drive from that to your pump so you can change gear ratios.

I'm a new sub and that boat is awesome I love it Catch you on another one my friend have a good day

Currently building another one at the moment stay tuned

the bottom of the boat in the rear needs to be more v shaped where the drive is. you should see less cavitation problems. the ramp should be shorter and steeper heading into the intake and long and shallow going from front to rear. earned a sub tho. love it also, spin the drive much faster. like 10,000 rpm

@JH1200A1

The pump intake will have to be a whole lot cleaner for 10,000 rpms and no cavitation. That engine will never spin it up that fast.

Considering where he is using it I think its going plenty fast enough. I just saw this first time tonight and new sub too. Guys like this is why America. They cant stop us. We will find a way. For anything.

Ok, if you feel that the boat needs better handling in the corners, you can add a ruder. This would limit the depth you could run, so make a dagger board like ruder. You could hook it up to a lever control on the other side or tie it in to the one you already made to steer the jet. the ruder could allow for a faster and safer run.

About the same speed as a 10 horse outboard. Very cool.

Good job

Good effort

I’d love to have the build plans for this project!!!!

I need this in my life.

Nice quiet serene creek with wildlife. Bet the natives loved you for that! Sometimes just because you can doesn’t mean you should.

The drive sounds so cool ! The motor not so much....something creative with the exhaust out the back or side maybe ? Just thoughts, Great work !

Fine work! Really went better than I thought. What was the jet pump out of? And need to be on the throttle for jets to turn, slow down sooner to be on the gas around the whole corner.

Doesn't seem to turn sharp enough but other than that seem pretty sweet

Bondo over the seam of the front of where jetski attaches to boat.

Get on go power sports and get some performance upgrades for the motor and a torque converter set-up

Cool build, but that loud motor would not work for me long term.

Now you should get with Red Beards Garage and build that engine. He's very knowledgeable.

What is that odd noise

Can I get some info on this type build

That pump needs to be spinning faster, you can hear that the engine isn't working very hard. Or you could put a more aggressive impeller in the jet.

Check out the Louisiana mud boats we make here You would be much faster with a skeg and prop We do it with a tunnel for inboards and fixed skeg they jump stumps run in mud and water lillies stacked up

Those are where it's at. Would it be better to use an air cooled motor for one or a water cooled engine with a heat exchanger?

@drifter9425

@@noturfather1106 If you wanna keep it simple and low horse go air cooled so you can chew thru mud and debris Some around here put little automotive engines in and do a heat exchanger but it's way more complex basically they put the cooler inside the boat on floor with super large capacity of coolant and let the seawater run thru front pickup and dump out the back being fed just on gravity For the mud and log jumping I would go with air cooled

@@drifter9425 all great stuff man. I want to make a mud duck boat, small and light enough for me to drag up the banks from where I launch but with enough power to push me through the thick stuff and over dams without getting choked up with weeds. I was thinking my old 12 foot john boat would be a good candidate then maybe cannibalize the shaft and skeg from a longtail motor kit for my stern drive creation

I like it

Pull that pull that governor put a rod in it from ARC and I think will fly

👍😎

Looks like fun. But turns like a barge. If you could figure out a better steering solution it would be bad ass.

With the clutch on there at idle when u let off the gas the shaft stops and thats y ur steering is bad at low speed

you think a go cart style torque converter would do anything different?

Not sure, building another one now might try that

with jet pumps brother its a;; anout high rpm thats why their all 2 strokes or 4 stroke street bike engines or turbos got to ditch the motor or change the gearing still cool though good job gbyaa!!!!!!!!!

Why are you running a clutch? No need, unless you have it set to only slip under a shock load as a safety for the engine. Also, I think that thing needs more gearing and I KNOW it needs a chain guard. Cool little boat though, would work great on the Tualatin near me

I have been slowly gathering parts for a simialar build. Have you considered a cvt style gokart cluch? They keep the engine in higher rpm range while allowing vairable gearing dependendent on load and would essentially give "neutral" while idling

​@@zakn3954 i agree with what you are saying neutal isnt needed Was more thinking neutral for easy pull starts/vibration at rest etc. and cvt to get the optimum gear ratio at any given time/load/rpm.

Sounds like belt slipage

To get better acceleration and torque you would need a bigger driven sprocket, small one on the engine and larger one on the propeller shaft. Unfortunately it looks as if there may not be enough room for a larger sprocket there.

Im not an expert or anything but I've seen people put torque converters on mini bikes and go karts and get better speed.

where is the intake located?

Prop needs a tunnel, if the rectangle box is where it is, because the water cant get to the prop quick enough.
