We Built a Jet Boat for Under $100 out of a Trailer Lid

[@CarsandCameras]

Leave a like if we should triple the power output!

[@rydplrs71]

You don’t need more power, you need a higher volume pump. I’m up for seeing version 1.2

[@ForeverLoco4]

All the power and jet drive!

[@brucipherwayne3997]

Hell.Yes.

[@FarmerFpv]

Yall smoked something real strong over the weekend. 😂

[@lasskinn474]

put gearing on the pump. cvt.

[@shawnpresby769]

Throw a reducer on the outlet under the boat and she will go faster. I used to drill piling holes for marinas with a similar pump and a (30') 2.5" "jet pipe". At the end we had a 2.5''' to 1'' reducer and it was powerful enough to carve out massive holes in the clay lake bed where I needed piling to go in.

[@FoolOfATuque]

That makes sense. Basically you’re adding way more velocity for the same pressure. Also this looks like a semi-trash pump which might not be as good as a high pressure pump. A high pressure pump would produce double the pressure.

[@jrkbgk1111]

We need to blow up this comment so John and the guys see it!

[@robertbrothers3733]

for sure need a nozzle

[@shockershooter]

They can channel the inlet and outlet and reduce drag from the bottom of the boat as well. It would also reduce the amount of debris and mud getting into the inlet.

Exactly. I was more excited to see this than any of the other KZbin jetboat build videos I've seen. Waiting for the canoe version. I'm imagining less drag with a canoe.

Try reducing the outlet diameter, it will increase the velocity of the discharged water. (Bernoulli's theorem)

[@Flastew]

Agree they need a nozzle on it to increase out let speed/pressure.

[@brushybillroberts2654]

@@Flastew the velocity of the flow increases, while the actual pressure drops. Again, Bernoulli's Theorem

[@legro19]

Not convince with the 90 they can achieve a laminar flow without loosing a ton of GPM wich if the case they will achieve nothing. We are not talking of and impaler in a pipe reving at crazy speed barely building up pressure. Just ading a straight pipe on the 90 will reduce turbulence a lot without loosing to much displacement. If they rev higher pressure will go pretty high with this kind of impaler.

You can wire wheel or grind the thin zinc coating off the steel in spots so you can weld it securely and safely without the bad fumes.

[@ThatPhilBurgGuy]

To be fair. Ghpc saw the mini jet boat on Cleetus McFarlands channel and copied his idea to make a tiny jet boat. They just actually followed through quickly because Garrett has so many more things going on and can't get to his. Basically bought the same boat and fast tracked the building of it before cleetus had a chance to and attracting views towards themselves when people search for mini jet boat after watching the cleetus video.

[@bannoch]

@@daltonengland7134 they put so much work into everything they do man they can’t fit it all in one vid

[@MjS-zb6jr]

You really need to increase the pressure coming out of the pump if you want to increase your speed. Try putting a smaller (nozzle) on the outlet. And put a lip on the back side of the inlet (pickup) so it feeds more water in easier when your moving.

[@legro19]

Don't need pressure at all only GPM. More you displace water more faster you go. 300 GPM pump at 8 psi will do better than a 100 GPM at 60 psi pump.

[@legro19]

Btw to get more pressure they just have to rev faster.

[@SilvaDreams]

@@legro19 Yes but you end up hitting a wall because of weight of the pump and it's like having a huge engine with lots of power and torque.. But a low ratio transmission. They just have a wide open pipe as the output you need some compression at the nozzle for better speed as it increases the speed of the water coming out.

[@legro19]

@@SilvaDreams The reason they put a restriction on jet boat is because it's an impaler in a pipe. The water is not going in straing ligne perpendicular to the pipe axis. she is spiraling in it (turbulence) so your water move slower on your axis but adding a restriction force it to accelerate to keep pressure equilibrium by doing so she stop spiraling and start moving perpendicular to the flow (laminar flow). Now they don't have a impaler in a pipe he is in a housing with a 90 at the exit and it's on purpose. So they don't have that much turbulence in it just a straight pipe will stabilise enough. Maybe using a bell like on jet boat (don't know the real name of the part) wich create aspiration at the exit of the pipe and direct the flow will help without reducing the volume of water exiting the pump.

[@xNELVKALEN]

Loved it. Wouldn’t mind more unique mini projects like this! Makes me wonder what y’all could create as far as mini boats go.

[@dylancrim7040]

Love how Charles isn’t even fazed by Issac’s excitement about the cast impeller

[@bombermanking]

Since ya'll are considering an engine swap I'd say to also make modifications to the water intake by adding a mesh like what Charles was talking about and a scoop so that water can flow into the pump easier. Also reducing the water outlet like what others have commented would make it a bit faster as well. PS. Been digging the content, keep it up!

[@Cybertruck1977]

Get rid of the underwater outlet. Jet drives work on reaction to the water blast. Not from pushing against the surrounding water. Jet boats discharge water into the air when the boat is on plane. Also like many have said reduce the outlet size a little to increase velocity.

[@dannistjana901]

Awesome video! Try adding a flexible hose from the outlet nozzle to a mount on the tiller for steering and possibly some extra speed, then maybe some different "jets" to the end.

[@bryduhbikeguy]

I was thinking the same thing with some radiator hose.

[@Ty-bz7zx]

For the intake, maybe a pipe or pvc cut lengthwise at an extreme angle and welded or secured to the bottom to make a channel* eliminating the 90 degree would increase intake volume and make use of forward velocity as well ?

Good call on not welding thru the galvi. Aside from the smoke,all your welds would need to be leak tested. However, for future reference, just grind the galvi down. You'll know it's gone when your grinding starts making sparks. This is a cool build. Another great change of pace!

[@thedude7726]

[@growlith6969]

A jet pump pulls as much as it pushes, angling the inlet helps. Like many have said, reduce outlet to increase output speed over volume. And then remember that jet pumps reduce engine efficiency by at least 1/3, so the more power the better.

[@HotGritz910]

Man I like Charles, he is down for whatever and is a hard worker. Hard to find young men like that.

[@yukon098]

Outlet does not need to be in the water, just creating drag with what you have now. like others said need a reducer too. Spin the motor around run outlet right out the back with reducer outside the boat, threaded so you can change reducers for optimal output. Put a small scoop on the inlet. Go fast.

[@SWINGERINTO]

Gonna need a part two!!!

[@jeremycardona85]

Guys if you if reduce the diameter of the output of the pump you will gain velocity, just a tip. Love what you do!

[@rimshot223]

I think if you add a nozzle to create more of a jet on the outlet and maybe face your inlet as more of a scoop toward the front; it will go faster. Fun build guys!

[@normanbrumley478]

You need to constrict the outlet. A job I worked at used the same type of pump with an old fashioned brass fire nozzle and the force coming out of it was tremendous. One guy made the mistake of letting go of it, and it whipped all over the place and nearly beat him to death before we could shut the pump down. You need more velocity coming from the outlet, and simply adding more horsepower won't help with that by itself. Think in terms of an attachment to a garden hose. 3/16" diameter attachment on a 3/4" diameter hose equals a stream with a lot of force. That's what you need to make your "boat" go faster. Maybe not fast, but at least faster. Good luck, and we'll be watching. (Love your channel) NOB

[@deathcogunit106]

Completely agree. I put a firehouse nozzle on my 2" trash pump and I wasn't expecting much. Well, I could barely hold on to the thing at full throttle. Big surprise.

[@saulverde]

[@eformance]

You could put a hose extension on the outlet, then "steer" the end of the hose to get directional control.

[@pablojanski.2559]

water intake face forward. Jet drives pull the boat forward. Keep that in mind. Look into how the Jet drives work and the design. Try and replicate. Great seeing you guys having fun. Keep up the great content.

[@thegreatgali1739]

I work with waterjet powered boats a bit at my job, some key points: 1. That pump will be like putting a v10 in a 60s Ford to make it go 80mph, its meant for low end loads. 2. Go for an angled inlet. The fast ones are like 15-25 degrees, but I bet 45 would be good enough. 3. As others said, DEFINITELY need a nozzle/reducer on the outlet. Not sure how you'd do it, but in the real thing, the nozzle rotates to turn the boat.

impeller in pump is threaded on crankshaft. behind the impeller is a ceramic seal which keeps water blowing by crank seal and filling crankcase up with water. I would reduce to 3/4" discharge with threaded metal pipe.

[@robertobuenrostro2781]

Flex seal fixes everything Ike. 👨🏻‍🔧

[@garchompy_1561]

I think swapping to a kayak or canoe and retrofitting the pump to that would yield an immediate improvement. plus you can get 3 man versions so you can all sit in safely. if you do that youll probably also be able to change the routing for the water, right now the water has to make so many 90 degree turns to get in and out who knows how much potential speed youre losing in that mess of flow.

John, get some copper sulfate and treat that scummy pond!

[@stevewheeler5097]

Put a reduction outlet nozzle on it. If you do this you turn volume of flow into increased speed due to pressure output. Just like putting a nozzle on a garden hose. Also make some kind scoop on inlet under boat to increase intake as your speed increases.

You have to reduce the exit size, the engine is like turning full RPM not using any torque, you have to make pressure to utilize the power of the engine to push the water out, if you leave it like that the water is just running through the pump whitout any force to push you.
