You're not getting cavitation. You're sucking air. And no that is not cavitation.

You should put handlebars on it and ride like a quad.

I need this in my life.

Nobody noticed the dog ran three fucking miles

nice job how fast

Bro been watching your videos for some time now. I grew up in Newaygo and jumped off the train bridge several times as kids.

Not spinning the clutch fast enough to engage 100%. Bigger clutch pulley size or torque converter, which is the best option

Nice boat for sure!!!

Next time put a go pro on bear , then you'll truly appreciate that loyalty, labs are the best I sure do miss my ol boy . Plus that would be cool footage....

So I'm in Kalamazoo. I tried to find you on social. Let's ride or hang out. Badass jetɓoat bro

He wants to go with you in the boat!

30 series torque converter, and chain drive.

Quite a sweet boat! When it dries up enough, I can wander by with the yellow pitbike, and we could add to your group video.

Run a water box to quite it down

Cool! Top speed?

awesome

Buy a bolt on torque converter give it some gearing

👍

Lol, the whole point of a flatboat is to have room to work....

Use a smaller prop, then no clutch needed. 😮

Cool project! And super cool to have that creek in your back yard.

Dude, you are going to burn up that clutch, its way over driven. You need bigger sprocket on the pump. Do not do a cvt, it will not give you more top speed than propper gearing on fixed ratio

My dogs heard the squeaker 😂😂😂

Do you fly that out of river Veiw airport or did you sell it? I remember seeing it. at your place and driving around town with it… just wondered what became of it

Hahaha. I know that creek and that house wait that’s my neighborhood! I love it send it!

Love the dog!!!!!

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

If noise is an issue, I noticed significant sound difference by putting together a 3 sided box made of the thick insulation foam board.

What jet drive are you using?

Love this, you got me wanting to build one....

Best thing to do is use a toothed belt and cam gear wheels, keep your ratio at 1:1 and it will be easy to start.The problem with moving a propeller or impeller in water is that the faster you go, the more power you need.

There's a video on my channel of a pretty decent mud motor exhaust

Bigger pulley and a torque converter would be the deal think of it as a mini bike with a 300 lb man on it

Exhaust out the Bottom will will be to much back pressure, ask me how i know😅

I want one

Try using the biggest pulleys that you can fit (with one side smaller for the disired drive ratio) but add a tensioner that you can pull back so it acts as a clutch like a lawn tractor. The bigger pulleys will have more grip

So if the clutch is hot, it's slipping. if not, dont worry about it but belts are made for higher linear speed than chains so you could run bigger pulleys on both ends and get more belt contact so it would slip less without having to do any of the crazy suggestions

If you put the exhaust just below the waterline pointed out the back, water back pressure will be minimal.

If you want to use a clutch you can get them with a sprocket for use with chain. But, there is a simple way to use a belt and pulleys and still have a clutch of sorts. I used to have a mini bike with this setup, and my old Snapper riding mower uses the same deal for the blade drive. You run a belt that is just loose enough that the pulleys can spin without the belt grabbing. In the middle of the belt you have an idler pulley or bearing, which is connected to a lever that you can engage into a notch. When you pull that lever into a notch it tensions the belt and off you go. It probably sounds easy more complicated than it is, but you could literally build it with two pieces of metal, an idler pulley(some people use a skateboard wheel) and a few bolts. If you wanted to get fancy you could make it engage with a steering cable so you wouldn't have to reach back. Of course that a little now fabrication work. As far as your exhaust situation, i would just run a pipe towards the back and just over the transom with a muffler on the end. You're not going to lose any performance. You'll probably gain performance over that short exhaust setup and it'll be way quieter. Cool project though. I found this vid because i just got an old 10ft jon and I'm looking at propulsion options.

What kind of speed do you get out of this setup?

Why did you not use a lovejoy drive.

I want to build me one

Ur exhaust is gonna act like a siphon when u shut the motor off

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 !

chain and clutch would work well

Definitely, buy a muffler and ixnay on the ufflermay out the ottombay of the boat.. look up a MOKAI. You can get ideas of function from their boats.

You should put a torque converter on it

Put torque converter on it

Go electric, super quiet, lots of torque

Nice !! Can't wait to see the final product and how it performs ! I'm thinking I'm gonna move my v twin towards the stern to just behind me and get it out of the bow and build a cover to go over it to quietin down the engine noise. Probably run the exhaust straight down the port and starboard side and have cutouts above the water on the sides just before the transom. Or just before the transom 45 them up with about ten inch risers . Fun unique project.
