What the hell is the Point Out of the water? The force is IN the water. The idea had merit the execution needs examination of a real jetdrive for understanding.
Submerge the pump deeper and add a shroud around the pump inlet screen with a forward facing inlet scoop to get some suction from the intake added to the push of the water jet. Just a thought
That's a cool idea! I'll bet with some tweaking of the nozzle, he could get a bit more speed. Maybe add another pump? Who knows? It's always fun to tinker! Great video.
These would make great thrusters for a larger homemade boat; two bow and two stern thrusters. A nice little joystick feeding the PWM would be really cool. You could have 4 seacocks for water outlets (the jets), all manually shut off for running and open for maneuvering, with 2 washing machine flow switches feeding flow to each seacock. The PWM logic could determine whether port or starboard side jets are activated by controlling the washing machine flow switch relays. You could incorporate a cutoff switch into each seacock so that the thrusters wouldn't work unless all four seacocks we're open, to protect the pump motors. The normal seacock inlet valve could be tapped to feed both bilge pumps. If it breaks somewhere remote, bilge pumps are available anywhere.

A kayak with a rooster tail! Just like a true racer, comparing speeds down to a tenth! Part got my attention the most, he said it uses less "amps"... which could mean better economy!
Dude great idea you may hv just solved my powering my little homemade skiff I’m building I I can put one of those on each side of my catamaran style scooter boat I’m making for shallow water, put o e on each side tied into same steering mechanism. Great idea gotta watch all of video to see if you reveal size of bilege pump
The video he talks about I think the guy was using 1100gph motors, two of them. They were also under $15 each, compared to over $100 for the one in this video.
Wow, actually was very cool. Very ingenious bcuz the pump is designed 2 b in the h2o, & the exhaust is providing thrust. Can upgrade 4 bigger pumps or mount multiple pumps 4 higher thrust. Curious is how noisy it is underh2o. Is there a way measure the sound in the h2o? Thx 4 sharing on Utube.
Thanks for video...have thought about this myself. I currently use a small all stainless 1973 trolling motor but its nothing special...lol. I'd like know any updates with nozzles of you keep using it. Thanks again.
He said at 5:14 when completely submerged he was getting 1.3 mph compared to 2.2 mph half submerged. The pump was probably struggling to pump the water out with the water pressure pushing against it and/or there's more surfing tension on the top of the water to give more force. I though it was too high too until I heard that.
I think that he would have been better off submerging the nozzle in the water, that way he could push water instead of pushing air. I know there is succion generating thrust too but my instinct tells me he's probably losing half the thrust by keeping the nozzle up in the air
Get the nozzle a little deeper to get better thrust....you would get MUCH better performance if you took the pump impeller and housing off and used a propeller in a thruster housing instead....
Agree..."something a little different" but it's technically no longer a bilge pump in this configuration. Used in this situation its nothing more than another battery powered propulsion device, impeller in this case. So I guess it comes down to your needs as the skipper, it's clear this setup is not as responsive as a traditional trolling motor and I'm quite confident the efficiency is no where close to what a standard propeller (screw if you want to name it correctly). IDK, only agree here that "it's something a little different". Thanks for sharing.
Is it quieter than trolling motor all the way in the water? Im really thinking that would be the only advantage in this other than just having fun doing the project to make it
Seems like it would be. But from my research nozzle 50% submerged is most efficient. Which kind of proved out in this test. 2.3 mph compared to 1.3 fully submerged.
Yea maybe put the nozzle deeper in the water?
I don't know the technical reasons but "jet drives" work better when the output nozzle is right at the waterline
My thoughts as well. He can get 4 mph if he can get it down further
@@HubcapPointOutdoorsif I'm not mistaken, they are also pointed into the water slightly

Right?? Doesn't take a genius to figure this out
I found this while looking at drill motor driven props for my Float tube. This might be the better idea for my tube.

That's pretty slick

Ive seen it all now lol. Cool man!
😮that’s awesome stuff man 😊
I'd definitely get the pump submerged a little deeper.
I went to a Heroes on the Water event a few years back out of southeast Louisiana. I have a lure 11.5 too
I was waiting for someone to do that. I knew I couldn't be the only one to have thought of it.
Needs to be lowered so the force is directed under the water and nozel angled slightly up
I just love the creativity but as for the cost a trolling motor setup would be a better choice.

That’s really good for a tiny little motor
Yes, I was going to say put it deeper in the water. I think it will go faster.
The video he talks about I think the guy was using 1100gph motors, two of them. They were also under $15 each, compared to over $100 for the one in this video.
Nice on that glassy pond but it's a bobber in any current or chop. Seems like a lot of effort for such a weak motor
Jet motors which this essentially is work by moving volume not lbs of thrust. So the bigger the pump the faster you go.

Wonder if you would get more power if you adjusted the nozzle and actually put it further in the water.

It was slower fully submerged than up higher
I am guessing 11 LB mass per second of water at full power should be flying out the back if there is no back pressure.
It definitely needs to be lower in the water
Cut the impeller out and throw a small prop on there and you could probably double your speed.
Maybe dual bilge pumps might get the speed of he wants😁🐟🐠
DIY JET Boat! Amazing!
could this be modified to suck thru the rear scuppers? eliminating the need for the pump to hang off the back.
Got me thinking 🤔
Cool idea.
Awesome video man! That's pretty cool. Great idea!!! By the way, I'm from Austin, and I fish Matatagorda a lot. I like your Gorda hat 😊👍
I’m going to build one with submersible pump.
Get the nozzle a little deeper to get better thrust....you would get MUCH better performance if you took the pump impeller and housing off and used a propeller in a thruster housing instead....
If you doubt my comment, have a look.... m.th-cam.com/video/DBNDEQjZI84/w-d-xo.html
I like that hat man I live there too
A little watersnake t24 will push that same kayak about 4 mph .
Part 2 of this video is coming soon!
IT WOULD WORK MUCH BETTER IF THE NOZZLE WAS DEEPER IN THE WATER!!
Turned a kayak into a jet boat. 😁
^5 (lower in the water)

Agreed. I also feel that if it is replaced with a thruster, the thrust conversion will be better. But the DIY idea is still cool.😁
I think it would be more efficient if the discharge was a little deeper. That discharge that is airborne is wasted effort.
Deeper dude
You can't get much propulsion with the nozzle out of the water.
I would think so too, but it actually is faster when it's out of the water.
I'd drop the motor another 4 inches. You lose a lot of efficiency with half the water coming up as a spray.
LOL. Since it's not a motor, do you still have to registered it as a motorized kayak in TX?
I was wondering the same thing it's a pump not a motor...
Yes.
Is it quieter than trolling motor all the way in the water? Im really thinking that would be the only advantage in this other than just having fun doing the project to make it
Sump pump is better, good luck guys!
Drop your nozzle under the water
That's fun but scare all the fish lol
The pump needs to be deeper in the water. I bet that would help a lot.
I see the gorda hat man im from matagorda county
👍👍👍
hmmm 24v should do even better... got me thinkin
Aren’t you wasting most of the energy by spraying water all Willy nilly
Seems like it would be. But from my research nozzle 50% submerged is most efficient. Which kind of proved out in this test. 2.3 mph compared to 1.3 fully submerged.
Wouldn't it go faster if it were lower in the water? Looks like your losing a lot of propulsion
Nevermind I saw your responses to earlier questions
How do I join army engineer vet

Get it under the water farther..
