I really doubt that motor is 4hp. I have seen 400watts (1/2 hp) advertized as 4 hp. Use a power conversion calculator or do the math 1,000 whatts = 1.3 hp
Two years later this motor is going strong ruclips.net/user/postUgkxBZWgzfpS2Jj7JqIHyaSZjyVHNUgCKCBf Just uploaded a video of it after 2 years. We use it probably a dozen days each year on our small raft.-original review- We got this motor the other day and tested it out. I don't have anything to compare it to, but it seems good to me. It has all the features advertised - the motor housing is metal. We will see how it performs longer term and I will revise this review if needed. Some initial observations:- Good thrust, moves our boat around really well- It comes with a circuit breaker but no switch - so there's no way to kill the motor other than yanking the connection off the battery. I installed an inline switch.- The mount bracket is plastic and I worry it might break- There are a number of plastic parts that I worry about, but the most important ones are metal or some kind of composite
A typical loss in jet outboards is 1/3 the motors rated horse power. I run a 60/90. 60 hp power at the jet with a 90 hp power head. Jet outboards in a river is all about "how shallow you can go" because there is no gearbox or prop below the bottom of the boat. With a 60hp at the jet my LOWES 1760 w/ a tunnel hull runs between 30 and 35 mph upstream in a 6 mph current. But remember avoiding obstacles in a river at speed is a challenge, but it is the speed that keeps you on top of the water running with minimal draft. It's like a game of "chicken" It is not "if you hit something" it's more of a matter of when. Yes my boat has some dents and has been welded. For your lake fishing....ditch the "jet" idea and run a prop. It's has a much better efficiency ratio letting you cover more area fishing. 😎
Had a 35HP jet drive which had a 50HP power head. Loved it. Didn't have to worry about stumps or rocks but did have to watch out for lily pads. Full throttle through the pads was ok but just don't stop. LOL. Used it on the Mississippi River backwaters.
The only jet drives I've seen are on a jet ski. I totally understand why and how jet drive boats can go in shallow water. How badly does sand or does sand wear away at the impeller? How durable are they? Just curious.
Thanks for reviewing the electric jet boat motor, so I won't waist my money on one. I still love my, 10 year old, Minn Kota 55lb Endura Max, with a new $120 EverStart Maxx Marine Battery, Size 29DC, from WalMart. That set up works great all day, even going 12 miles up river to a Lake where most boats can't go & running the nav lights, so I can be there at first light. I have a 14' flatback canoe & a Bass Raider 10E. I get 7mph with my canoe & 5mph with my Bass Raider, going up wind & up river, loaded with 2 heavy people. (about 10-12mph down wind & down river). FYI: I always go up river first incase I breakdown, which happened once when the fuse blew & I didn't pack a spare, paddling down river is much easier.
I’d like to see the comparison with the the 2 electric out board motors and the troller motor with those power wheel batteries you got. Leave a link also.
I'm from Wisconsin & I have a friend that owns a 16 acre pond..Only can use trolling motors..I have a little 10' Allunimum V-bottom with a Minn Kota Endura Max 55 lb thrust & a 12 volt Optima Battery..It goes about 5-6 MPH.Catch 3-6 lb Bass all day long 👍
That’s what I was thinking too. Might not make as unique a subject for a video but a MinnKota would make a simpler, more practical and less costly option.
Seems like a trolling motor with a ducted fan, I don't know if it would be any better than a regular trolling motor, but its kinda cool. I'd like to see how well it handles weeds.
It's not a 5HP motor. It’s rated at 1000 Watts that's 1.34HP. The Amp draw is about 21 Amps. The Battery is 14Ah so max time is about 40 minutes of total time while on. The battery is way undersized but probably didn’t effect top speed much just run time. Manufacturer recommends 30-100Ah while you had 14Ah. You know the motor is junk and overrated when they hide the thrust. You could have figured out the pounds of thrust with a digital Luggage scale hooked to a rope held back by the dock. The jet is a gimmick and you would have way more thrust with a prop drawing the same Watts. You didn’t even have life jackets on or even in the boat!
Some have said it already but I'll say it and explain it. The jet output needs to be above the water. Do that and you'll go faster. The reason is that when you shoot the jet out under the water, the water itself is resistance. It's as if you were blocking the jet with your hand. Look at any video of a boat with a jet drive and you'll see they all have the jet spraying out above the surface of the water. Please try this again with the motor mounted higher so the jet shoots out into the air. It looks like the mounting bracket allows for easy height adjustment, and it's probably for the very reason I explained. It might be a bit of a balancing act to get the intake deep enough to not suck in air and the output high enough to spray into the air, but I guarantee it will go faster! I subbed and I'm hoping you do a follow-up video!
jets lose about 30% in HP reduction due to inefficiency in propulsion. 60hp jet drive is really a 90hp motor or vice versa. 5hp probably runs at 3 HP. Other factors like the impeller and how close it is to the sleeve (wall) can greatly effect performance. Jet impellers need to be adjusted for very tight tolerance to get maximum thrust. There are other factors as well. I am sure if you put more juice to that thing you could get a little more out of it but if you're looking for performance you go with a prop.
@@t-bone43 That is not inherant to all jets. Just the ones that were designed in the 1950s to0 be bolt ons to a number of outboards lower units. They are basically the only outboard jets that you will see todayl. But while most single propellors ope4rating within their designed limits are at most 65% efficient at turning motor power into boat movement, many modern jets reach 90% efficiency at their design speeds.This lil jet motors biggest problem was that it was discharging underwater instead of into the air. That wastes 30% of the the horsepower that it used
Water jets have the best tow capacity. That's why Towing boat's are all jet powered today. The motor of this video dont have a Resonable rpm to achive speed results. Good water jet need to reach 8k-9k RPM. In term of electric water jets, they can reach 10k-35k RPM...
just a casual hint that generally when you're full dumping batteries they need room to swell with temperature. the ratchet strap is strong enough to turn this into a volcano science experiment
Man, These batteries cannot deliver more than 14 Amps of power, 48Vx14Amp = 670 watt or 0,5 hp. To get full power out of the motor, you MUST connect it to a battery which can deliver the rated power. Even if you want the cheapest possible version, you should use a proper complete system. Kids toys batteries probably do not even deliver these 14A. If you wanna know, what the motor can do, connect it to a lithium battery 48V with at least 3kW of power. You do not fill tomato juice into a gas tank and expect engine running well. Don’t do exactly the same with electric motor….🙈
Moving from prop to jet pump there is typically a 30% loss of realized power. Them just slapping a jet on a prop motor won't compare to the prop version. Real jet boat motors are made to run at optimum levels to support the jet pump. Jet boats are definitely not slow because they take the power conversion loss into account.
You mentioned drinking beer in your garage all day.... Meanwhile I'm watching this while sitting at my workbench in my garage and drinking a cold one while watching this. Cheers from Texas!🍻
For 1 jets have about 30 percent less power. You also mounted the motor wrong. The bottom of the motor should be level with the bottom of the boat. BTW I live in alaska and we do a lot with jets.
Voltage is speed with Emotors, checking what voltage is getting to the motor and how much it drops when operating (current usage) will let you know what needs to change for better performance...fun project I bet, even with chinglish information. Outboard configuration is really bad efficiency for the jet drive also, direct in line motor-drive would impress you better lol 😆
I DON'T KNOW IF THIS WILL WORK BUT DECADES AGO WE HAD AN ABOVE-GROUND POOL IN OUR YARD AND THE PUMP/FILTER HAD A PVC HOSE OF ABOUT 1-1/2 INCHES IN DIAM. I USED A VACUUM ACCESSORY THE LONG THIN ONE AND CONNECTED IT TO THE OUTPUT PVC HOSE. THIS INCREASED THE OUTPUT PRESSURE GREATLY AND WE MADE A POWERFUL WHIRLPOOL AND HAD A BLAST. PERHAPS ATTACHING A PVC WITH THE SAME DIAM AS THE OUTPUT ON THAT MOTOR BUT MUCH SMALLER AT THE OTHER END. IT MAY INCREASE YOUR SPEED GREATLY?? I HAVE HAD IDEAS ALL OF MY LIFE AND THIS IS ONE I HAVE BEEN WORKING ON.
I never understood why these Chinese companies don't just hire one person that has one simple job... To translate into actual English for their products.
Can you raise the (assembly) in the mount enough for the nozzle to be above water when using it? A jet drive will produce more torque when the pressurized water is released into atmosphere instead of underwater.
🤣🤣🤣 yeah why didnt the manufacturers route the jet above waterline? Torque and thrust are not the same. If it was like that, all outboards would be pushing out in air instead of water. It needs the backpressure of the water to move the boat forward. Its not an airplane
I ran that electric for over a year on 48v non jet model, it survived several swampings in saltwater!! the readout died, switches died, replaced the twist grip with ebay ebike sw. but if you clean off the contacts for the battery it still goes
Next time you take that puppy out, I'd suggest feeling the wires to see how hot they're getting. 4 HP is about 3000 watts. With a 48V battery, that's over 60 amps. That wire and the tiny connector are rated somewhere near 10-15 amps. That style of battery is only rated to put out a very limited amperage before overheating and reducing life. I suspect the speed is so low because of all the losses across the wire, battery and connector(s) Incidentally, 48V is enough to kill someone if you mix it with water and take current across your heart. Like positive on one arm and negative on the other. From an engineering and safety standpoint, that setup is a disaster.
I put a minnkota electric trolling motor on my canoe with a motor rig and it would go around 8 to 10 mph... Super quiet and got me around a lake that would not allow gas motors...
My brother use to have a 21 ft john boat with a 60 hp and a jet drive. He could easily take that thing 40 MPH down a river, and could skim across areas that were only inches deep. I went out with him a few times, and that thing would really get your blood pumping.
you should find a cooler to pit the battery in to keep it dry. just drill a hole in it and use some foam or epoxy to fill the hole and its water tight.
48V. They were running the motor on undersized batteries. There batteries equaled 48v total but there Amp Hours were well below the minimum requirements for that motor.
You can get a quick release thread for the transom tilt. If your battery is not optimal output you will not utilize the full potential of the motor. All jet drives reduce the power output even in gas jet drives. You lose 28 to 32 HP depending on your setup.
Place fish in the water, gently supporting the mid-section and tail until it swims away. Resuscitate an exhausted fish by moving it or facing it into the current, gently forcing water into the mouth and over the gills. Watch the fish when released. If it doesn't swim away, recover it and try again.
If it were me I would buy a Minnkota trolling motor that operates on 12 V. You can get one for $120 that has 30 pound thrust. I’m pretty sure it would go faster than 3 mph.
u need lift it up enough it sitting too deep jet motor same as jet ski but need more rpm in order move faster one u got jet blade is too small so aint going any faster than 3 mhp
Definition of engine a machine for converting any of various forms of energy into mechanical force and motion also : a mechanism or object that serves as an energy source black holes may be the engines for quasars.
So just tell you our boats are usually slower than jet boats jet boats are usually faster if you have the right stuff but if you could put the same motor in the jet boat and a normal boat or capella boat the jet boat would be slightly Faster by one mile per hour
But that's also thinking of a actual jet mode like an actual actual jet boat motor compartment instead of a Troll Motor chat so now I'm also thinking of like a yeah 8 cylinder they should all be somewhere in there
Awesome awesome something you could do just to look at it and take a like really powerful RC motor on it and shove it inside a Bare Bones outboard motor and just see what it does
Lol maybe I should have grabbed a paddle..and a couple life jackets might have been a decent idea 😬 Weird thought about not having “reverse” on old 2 cycle outboards the power head swivels 360 so you can point it to drive in “reverse “. Just something to try.
Don't feel bad I Bought the gas version you might go 3 mph lol it's sitting in my closet until I can find a small one person boat my 1957 duracraft had a 1975 Chrysler seeking 15 hp you could go maybe 20 and drinks fuel replaced that with a Yamaha 15 hp 4 stroke almost 30 mph and sir you are not Lying boat motors are not cheap 3000 for that 15 hp could just imagine some of them nicer bass boats with them 150 hp motors on them cost stay safe like the video
So virtually worthless lol. That thing is 2hp at best. Not a chance it's 5hp. For the same price you can get a 12 volt 65lb thrust trolling motor that can 1. Go in reverse. 2. Doesn't need 200lbs of batteries in series. 3. Weighs 1/10 what that motor weighs. 4. Is most likely faster. 5. Is quiet.
Certified POS. But I will have to say it is amazing how you can buy this for less than a gallon of gas in the US right now. Build back better in every other country but ours!
Motor=generates force, thus motivating a movement. Engine=two or more simple machines combined to work together to transfer force and movement to accomplish work. A pair of pliers are two levers combined to transfer force are an engine. An internal combustion engine is an Internal Combustion Engine Motor.
The 10hp electric HANGKAI model is listed as 60V 38A(rated current) = 2280w (rated as 2.2KW) Whilst the 8hp electric HANGKAI model is listed as 48V 50A(rated current) = 2400W (again rated as 2.2KW) What is the reason for the discrepancy? Is the 10hp model more powerful?
If you’ll raise the motor to where the bottom of of jet port is only about 5 inches below the water you’ll get more speed. If a jet propulsion nozzle is too deep in the water you get very limited propulsion.
A short 10ft boat isn't going to be very fast unless he gets it up on plane, for that he will need more than 5hp. His longer boat probably was faster even though it was heavier. My 23 ft sailboats hull speed is around 6mph, pretty much no matter how much power. So yeah, that little 10ft isn't going much faster until he starts putting way more power than its rated for. Btw I have the same boat, kinda wish I had gotten a 14ft instead.
Yo what is with youtubers installing boat motors ON THE WATER!?!?! Also.........not 4hp!. 4hp is slow but not that slow! To answer ur question........are jetskis slow? And yes......English actually is hard if its not ur mother tongue.
That motor can propel you WAYYY faster than your experiment proved. You’re putting 4, 11 amp hour batteries in series to create the 48 volts the motor wants. So you’re using 48v DC at 11 amps (tops). That motor probably draws 30-35 amps at full power (conservatively). The more weight on the boat, the harder the motor works and the more amperage it needs. If you have a LifePo4 battery rated at 100 amp hours, you could go at least 3x’s faster. But those are expensive and I’m not sure if they even make one in a 48 V option. But if you got yourself four car batteries and put them in series you could easily get the amperage necessary to push that thing to its limits. Batteries in series: voltage doubles (or triples/quadruples depending on how many batteries you use) and amperage stays the same. Batteries in parallel: Voltage stays the same, amperage doubles, triples, or quadruples). You need more amperage!
100% know why it was slower. WRONG BATTERY AND CABLES. EV anything require amperage over voltage. You have the voltage. You even have the amp/hours available. The problem is the wires are too small. Those batteries, nor the wires you are using, are NOT rated for the high amp discharge required for that motor. Image this. you have a car battery that needs jumped. You can't use 22 gauge wires to jump a battery even if the other battery is fully charged and brand new. Why? Because it can't pull enough amps to turn the starter. That's why jumper cables are thicker than the normal battery cables. It accounts for the net loss of energy in heat through the transfer from one battery to another through the cables. In short, you need the correct battery and cables to make it work.
Ok.....but I'd rather go with a budget Chinese 6HP two-stroke....I have seen cheap mods on both the props and a homemade planing fin that improves overall performance.....easily moves one passenger on a small jon or inflatable at 12-15 mph with ALL DAY range. Both are toys but the 2-stroke seems more dependable overall
A jet drive on a small crappie electric or gas motor will never work good... I had a new 5hp 4 stroke jet drive and it was so loud because the motor is near your head... I Had a 10ft Jon boat with nothing in it... It was a joke... The jet drive design is plastic crap... I've only seen real jet drives on big horsepower motors cause you need the horsepower and rpms and a metal impeller n metal housing... Do not waste your money on that crap... I bought a new 2.5 Suzuki 4stroke...29lbs...$700 to my door and it's perfect for a kicker or small craft...
Your not getting 5 hp out of that. I had a 1-1/4 hp gas job and got more speed then you are. The math is 750 watts per 1 horse power. 750x5=3750 watts. Look at the specs on that motor and I doubt it is pulling half that. Find out the voltage rating on that, it might be 24 volts, if not look into battery AH output. Maybe a lithium battery with a high "C" rating will help but try and borrow one for they are super expensive.
Lead batteries with 100 ah are priced at 150.00 and weigh 70 lbs. LiFePO4 batteries at same level are 500.00, but weigh only 25 lbs. All Li batteries are made in china and some fail and there's little support past 30 days. With battery need a Battery box 100.00, and charger 30.00. Small Honda outboard with 5 year warranty is 1000.00. I chose the Honda engine
Electric transportation anything is just a waste of money unless you have an electric golf cart to go 5 blocks to Circle K or 7-11. The ideas are good but the technologies just won't be here for another 100 years. Societies will be fossil fuel celebrated until then, fill it up with +104 octane please!!
Please buy a 5kwh 48v lifepo4 server rack battery. $1.5k and it's 10 year 80% discharge rating eliminate all benefits of lead acid. Just caulk it heavily. If water gets in it becomes a giant fireball unlike lead acid
Not boaters apparently... You don't crack aluminum .. So seems few follow boating rules.. no wake zone automatic if boaters swimmers fishing in area at normally 50 to 500 feet ...
O.k. yes sounds terrific. I read a lott of comments and views and yes these plumbing pipes in the water really slow🤩you down. Lol. Cut a hole in the bottom on the boat and then put the jet part going out of the back of the boat now you can be a maniac and run over things. I would really ❤ to see you do that. As to the three bladed one replace the three bladed one with a two bladed one you can try different sizes and it will be more efficient so you will go a lot farther. That means battwry will last longer at the same speed. Rachel I think you need some new outfits.! If you are going to be on any more videos. Some people are just watching because of you. Get her sonething nice!!!! And she will jump up and down when you catch a fish. Lol
I apologize sir, I just got wound up and really worried when you electrocuted yourself live, and when you almost sunk the boat, or your questions about the effeceniancy of jet boats to props?? I don't know more importantly 'who cares'. Have a good day bro I sory
Jet boat motors are way less efficient, so they take much more power to get the same output. This is just by design - they have other advantages, but by far the disadvantage is their poor efficiency. My jet boat burns through ~$150 in gas every time I take it out. Fun as hell, but efficient it is not.
Well you said 4 or 5hp I just went with 5 so that's like 3750 watts so 78 amps at 48v and that was like 12awg I think I have seen those small batteries say they can do 100amps but probably not for long and ya like 12awg maybe 10
Mercury Thruster offers over 55 pounds of thrust, this motor is junk, 3 miles per hour sucks. My thruster runs 5 miles per hour and even it's to slow for main power. Good luck if any wind blows, you'll never make it back to the ramp. LOL
I looked for a but I can't find it. How does it take an Australian to tell you that a "jet boat" literally means impeller not a propeller. Imagine a hose shooting out water (high pressure,low volume) VS a bath with a fan ( high volume low pressure)
I would like to know the longevity of them. If they only work for a short time then they are not worth the cost, I have two trolling motors with about 500 hours on them and they are still working well but I'm looking for more power for the cost. You said that those are 4hp and a trolling motor with 55lbs of thrust is a little under a 1hp motor.
Sorry to say but your boating safety leaves something to be desired. Starts out with no paddle. Than no lifejackets (1 per person) . No throwable cushion. Batteries not secured in a proper container. No marine-rated fire extinguisher and no emergency signaling devices.
On a outboard motor, whatever the hp is? 30% is loss using a jet compared to having a prop! That's why river rats always have 60-90 hp on 16' - 20' Jon boats!
Next time, spend your dough on a dyi handbook for the "tool and physics challenged", aka: millennial, aka: I speak in errors b/ I literally don't know **it about life.
This makes no sense. If it had an intake poet like a jet ski you would lose a large amount of drag. I had a 5 hp Tohatso motor as a back up on my small 13 foot Boston Whaler and it moved that much heavier fiberglass boat right along pretty easily and much quicker then this. Jet drives are for very shallow water river creeks where hitting rocks or stumps are the reason a prop is too risky.
This is good for a back up motor you do need life vests and Paddles and safety orange flags and a fire extinguisher and a wisseal or horn boat tags an anchor anyway best of luck. GOD-BLESS.
I don't think that motor is a 5 horsepower motor. My horsepower would be more like 3.7 kilowatts. That would draw over 300 amps off your 12 volt battery when you turn it on top speed. That much current through those little wires would make something very hot. I think you should compare your motor to a 50 lb thrust trolling motor which is about the same as a one horsepower motor.
you sure are special.....lol I bought a 79.00 electric trolling motor from a big box store and a lawn mower battery for 69.00 that is probably 10x faster!
Nice videos btw But your baterries only drains 12a you need at least 23amps yo get 1000w of your motor. Thats why you are half speed. Sorry my bad english
From my own experience of trying to learn and design impellers and props for electric motors, your impeller just might be poorly designed. More power may help, but you'll heat up the motor and it will degrade really fast down the road. I have a pile of them, because I am so hard headed. :)
I don’t know if anyone said this but 12v batteries on a 48v motor. I’m sure if you invested in a 48v e bike battery or electric lawnmower battery it would go much faster!
Comparing apples to oranges with both motors and batteries. A 40hp gas motor with a prop will get about the same as a 60hp jetdrive. as for small electric boats just go with a trolling motor an lithum iron battery . pro fishermen have bee using then for years, chances are they know
Grab a little RPM counter and see if impeller is hitting its rated RPM. could prob take off that silly "jet boat" housing and have a bare impeller that would work better.
jet boats also can suck stuff in and just get equally stuck on stuff personally I prefer propeller because jet puts out so much more sound and scaries fish more then say a prop but can you catch fish maybe but you also might scare more fish the only thing worse is a airboat terms of noise. I use a kayak 99% time i go places most people can't go doing alot marsh fishing.
I probably would have just disassembled that little electric drive motor, figured it out some kind of way the rig it up on a two stroke gas engine, give it a little bit more ponies, like 20-plus.
DROP ME A COMMENT 👊🏻
Yes I know, it’s a motor not engine 😂
Ps, batteries were $169.99 Vs. $400 from the last setup
The tip was the order to put the terminals on so you don't cause a voltage spike. Which was probably the kick you got 😂
Another thing is making sure the depth of the jet below the bottom of the boat.
First this.
Engine and Motor are the same despite all the goofy arguements.

Secondly where can you get the 48V pack for that price?
My old Minn Kota 12V trolling motor (40 pounds thrust) does 4mph.
I really doubt that motor is 4hp. I have seen 400watts (1/2 hp) advertized as 4 hp. Use a power conversion calculator or do the math 1,000 whatts = 1.3 hp
Two years later this motor is going strong ruclips.net/user/postUgkxBZWgzfpS2Jj7JqIHyaSZjyVHNUgCKCBf Just uploaded a video of it after 2 years. We use it probably a dozen days each year on our small raft.-original review- We got this motor the other day and tested it out. I don't have anything to compare it to, but it seems good to me.

A typical loss in jet outboards is 1/3 the motors rated horse power.
I run a 60/90. 60 hp power at the jet with a 90 hp power head.
Jet outboards in a river is all about "how shallow you can go" because there is no gearbox or prop below the bottom of the boat.
With a 60hp at the jet my LOWES 1760 w/ a tunnel hull runs between 30 and 35 mph upstream in a 6 mph current.
But remember avoiding obstacles in a river at speed is a challenge, but it is the speed that keeps you on top of the water running with minimal draft.
It's like a game of "chicken" It is not "if you hit something" it's more of a matter of when. Yes my boat has some dents and has been welded.
For your lake fishing....ditch the "jet" idea and run a prop.
It's has a much better efficiency ratio letting you cover more area fishing. 😎
Thank you for the information I was thinking about switching over to jet but mostly fish lakes.
Again thank you for sharing this
I originally bought it for rivers here, but I took it on a lake assuming poor performance 😅 hahah
@@elbertmoore7876 k
Had a 35HP jet drive which had a 50HP power head. Loved it. Didn't have to worry about stumps or rocks but did have to watch out for lily pads. Full throttle through the pads was ok but just don't stop. LOL. Used it on the Mississippi River backwaters.
The only jet drives I've seen are on a jet ski. I totally understand why and how jet drive boats can go in shallow water. How badly does sand or does sand wear away at the impeller? How durable are they? Just curious.
Thanks for reviewing the electric jet boat motor, so I won't waist my money on one. I still love my, 10 year old, Minn Kota 55lb Endura Max, with a new $120 EverStart Maxx Marine Battery, Size 29DC, from WalMart. That set up works great all day, even going 12 miles up river to a Lake where most boats can't go & running the nav lights, so I can be there at first light. I have a 14' flatback canoe & a Bass Raider 10E. I get 7mph with my canoe & 5mph with my Bass Raider, going up wind & up river, loaded with 2 heavy people. (about 10-12mph down wind & down river).
FYI: I always go up river first incase I breakdown, which happened once when the fuse blew & I didn't pack a spare, paddling down river is much easier.
I’d like to see the comparison with the the 2 electric out board motors and the troller motor with those power wheel batteries you got. Leave a link also.
Tip # 1001....keep Rachel in the videos. Hotness at level 💯 or 🔥!!! 👍😂
I'm from Wisconsin & I have a friend that owns a 16 acre pond..Only can use trolling motors..I have a little 10' Allunimum V-bottom with a Minn Kota Endura Max 55 lb thrust & a 12 volt Optima Battery..It goes about 5-6 MPH.Catch 3-6 lb Bass all day long 👍
That’s what I was thinking too. Might not make as unique a subject for a video but a MinnKota would make a simpler, more practical and less costly option.
Do you think it would keep up with a faster flowing river? I have a 10 ft west marine plastic dinghy and I want to take It up some smaller rivers
Seems like a trolling motor with a ducted fan, I don't know if it would be any better than a regular trolling motor, but its kinda cool. I'd like to see how well it handles weeds.
my 70lbs trolling motor doesnt care about weeds at all.. its just the cheap ol 30lbs motors that struggle a bit.
@@larsvegas1505 AWESOME... one comment two years later! That is amazing.
It's not a 5HP motor. It’s rated at 1000 Watts that's 1.34HP. The Amp draw is about 21 Amps. The Battery is 14Ah so max time is about 40 minutes of total time while on. The battery is way undersized but probably didn’t effect top speed much just run time. Manufacturer recommends 30-100Ah while you had 14Ah. You know the motor is junk and overrated when they hide the thrust. You could have figured out the pounds of thrust with a digital Luggage scale hooked to a rope held back by the dock. The jet is a gimmick and you would have way more thrust with a prop drawing the same Watts. You didn’t even have life jackets on or even in the boat!
Some have said it already but I'll say it and explain it. The jet output needs to be above the water. Do that and you'll go faster. The reason is that when you shoot the jet out under the water, the water itself is resistance. It's as if you were blocking the jet with your hand. Look at any video of a boat with a jet drive and you'll see they all have the jet spraying out above the surface of the water.
Please try this again with the motor mounted higher so the jet shoots out into the air. It looks like the mounting bracket allows for easy height adjustment, and it's probably for the very reason I explained. It might be a bit of a balancing act to get the intake deep enough to not suck in air and the output high enough to spray into the air, but I guarantee it will go faster!
I subbed and I'm hoping you do a follow-up video!
Still waiting on the follow-up to this ;)
Yeah me too
jets lose about 30% in HP reduction due to inefficiency in propulsion. 60hp jet drive is really a 90hp motor or vice versa. 5hp probably runs at 3 HP. Other factors like the impeller and how close it is to the sleeve (wall) can greatly effect performance. Jet impellers need to be adjusted for very tight tolerance to get maximum thrust. There are other factors as well. I am sure if you put more juice to that thing you could get a little more out of it but if you're looking for performance you go with a prop.
That is correct. A 150hp jet outboard only produces 105hp of the jet pump.
@@t-bone43 That is not inherant to all jets. Just the ones that were designed in the 1950s to0 be bolt ons to a number of outboards lower units. They are basically the only outboard jets that you will see todayl. But while most single propellors ope4rating within their designed limits are at most 65% efficient at turning motor power into boat movement, many modern jets reach 90% efficiency at their design speeds.This lil jet motors biggest problem was that it was discharging underwater instead of into the air. That wastes 30% of the the horsepower that it used
Water jets have the best tow capacity. That's why Towing boat's are all jet powered today.
The motor of this video dont have a Resonable rpm to achive speed results. Good water jet need to reach 8k-9k RPM. In term of electric water jets, they can reach 10k-35k RPM...
just a casual hint that generally when you're full dumping batteries they need room to swell with temperature. the ratchet strap is strong enough to turn this into a volcano science experiment
Say as I do, don’t do as I say 😅 or what ever the saying is 🤷🏻♂️
And some batteries require compression in that same situation.
He should have linked two up
@zombuwulf lifepo4 batteries need to be compressed in high amperage applications.
@@TightlineTVEnglish is hard 😉
Man, These batteries cannot deliver more than 14 Amps of power, 48Vx14Amp = 670 watt or 0,5 hp. To get full power out of the motor, you MUST connect it to a battery which can deliver the rated power. Even if you want the cheapest possible version, you should use a proper complete system. Kids toys batteries probably do not even deliver these 14A. If you wanna know, what the motor can do, connect it to a lithium battery 48V with at least 3kW of power. You do not fill tomato juice into a gas tank and expect engine running well. Don’t do exactly the same with electric motor….🙈
Moving from prop to jet pump there is typically a 30% loss of realized power. Them just slapping a jet on a prop motor won't compare to the prop version. Real jet boat motors are made to run at optimum levels to support the jet pump. Jet boats are definitely not slow because they take the power conversion loss into account.
20% loss that’s why they call a 60hp a 60-40
@@aaronhill7197 You don't really think dropping from 60 to 40 is 20% do you? 20 is 33.3% of 60
It’s an electric version of an Australian 2 stroke outbound motor from the 70s called the Victa Jet. It’s a pity it doesn’t have a front facing intake
You mentioned drinking beer in your garage all day.... Meanwhile I'm watching this while sitting at my workbench in my garage and drinking a cold one while watching this. Cheers from Texas!🍻
IN FNQ AUSTRALIA WE TOO ARE KNOWEN TO HAVE A COOL BEER ,OR 2 ON A HOT AFTERNOON cheers from the Hull river FNQ
That's very impressive!
For 1 jets have about 30 percent less power. You also mounted the motor wrong. The bottom of the motor should be level with the bottom of the boat. BTW I live in alaska and we do a lot with jets.
Voltage is speed with Emotors, checking what voltage is getting to the motor and how much it drops when operating (current usage) will let you know what needs to change for better performance...fun project I bet, even with chinglish information.
Outboard configuration is really bad efficiency for the jet drive also, direct in line motor-drive would impress you better lol 😆
Voltage is speed ? Really ? Please don’t post if you have no idea what you are talking about 🤦♂️
These motors are now selling on Amazon for around $220. I guess they lowered the price because they're not good.
That battery probably can't handle the amperage the motor really needs
Yup, at 4 HP and 48 VDC your talking 62 Amps full song and should be like 6 AWG jumper cable wire to connect it up…
I DON'T KNOW IF THIS WILL WORK BUT DECADES AGO WE HAD AN ABOVE-GROUND POOL IN OUR YARD AND THE PUMP/FILTER HAD A PVC HOSE OF ABOUT 1-1/2 INCHES IN DIAM. I USED A VACUUM ACCESSORY THE LONG THIN ONE AND CONNECTED IT TO THE OUTPUT PVC HOSE. THIS INCREASED THE OUTPUT PRESSURE GREATLY AND WE MADE A POWERFUL WHIRLPOOL AND HAD A BLAST. PERHAPS ATTACHING A PVC WITH THE SAME DIAM AS THE OUTPUT ON THAT MOTOR BUT MUCH SMALLER AT THE OTHER END. IT MAY INCREASE YOUR SPEED GREATLY?? I HAVE HAD IDEAS ALL OF MY LIFE AND THIS IS ONE I HAVE BEEN WORKING ON.
I never understood why these Chinese companies don't just hire one person that has one simple job... To translate into actual English for their products.

I love the part where Rachel divides you and you became Rachely divided
Jet motors are about 30% less powerful so you were probably only running at about 2.8hp. I would like to see how the trolling motor compares.
Math is wrong but yes that's the reason. Jets are about 1/3 less power when compared to the same power prop engine.
@@lowvpro9651 What do you mean math is "wrong"?
@@MrWhiltetail I get 3.5hp subtracting 30% from 5hp.. thought he said 5hp, but maybe that's were the math difference is..
@@djmjr77 @13:34 he states he thinks the prop version & this one are both 4Hp because they are the same wattage. So I went based off that.
@@MrWhiltetail yea that'll do it, I thought I heard 5.. didnt go back to check..
Can you raise the (assembly) in the mount enough for the nozzle to be above water when using it? A jet drive will produce more torque when the pressurized water is released into atmosphere instead of underwater.
why?
Yeah why? And how? By torque do you mean thrust?
I'm not an expert but in theory it makes sense. Water will move thru air faster than thru more water
That is not true, 😂.
🤣🤣🤣 yeah why didnt the manufacturers route the jet above waterline? Torque and thrust are not the same. If it was like that, all outboards would be pushing out in air instead of water. It needs the backpressure of the water to move the boat forward. Its not an airplane
You need at least 48v battery 100amp not 14. This motor use 25amps at full speed. With a good 48v battery this boat should go at 6-7mph
I ran that electric for over a year on 48v non jet model, it survived several swampings in saltwater!! the readout died, switches died, replaced the twist grip with ebay ebike sw. but if you clean off the contacts for the battery it still goes
why not get a electric prop motor🤷🏻♂️. What are the advantages of the jet besides the cool name? Way less friction and parts with a prop. Just saying
Next time you take that puppy out, I'd suggest feeling the wires to see how hot they're getting. 4 HP is about 3000 watts. With a 48V battery, that's over 60 amps. That wire and the tiny connector are rated somewhere near 10-15 amps. That style of battery is only rated to put out a very limited amperage before overheating and reducing life. I suspect the speed is so low because of all the losses across the wire, battery and connector(s)
Incidentally, 48V is enough to kill someone if you mix it with water and take current across your heart. Like positive on one arm and negative on the other. From an engineering and safety standpoint, that setup is a disaster.
I put a minnkota electric trolling motor on my canoe with a motor rig and it would go around 8 to 10 mph... Super quiet and got me around a lake that would not allow gas motors...
Is it a jet drive....?
Looks like a prop inside a drainage elbow to me..!
My brother use to have a 21 ft john boat with a 60 hp and a jet drive. He could easily take that thing 40 MPH down a river, and could skim across areas that were only inches deep. I went out with him a few times, and that thing would really get your blood pumping.
How can it possibly be slower? It has the word "jet" right in its name!!! LOL 😂😂👍👍
Can't you just spin the motor all the way around when its mounted to reverse?
Yes probably 😂 not sure if cable is long enough
a water jet is supposed to sit above the water, if its actually a jet then thatll be why its shit when slow
you should find a cooler to pit the battery in to keep it dry. just drill a hole in it and use some foam or epoxy to fill the hole and its water tight.
I would like to see the prop version on the small boat with the new battery setup. Cheers
Is it a 24v motor or 12v? If it's 24 and you are running on 12v you could be missing the full range of power
48V. They were running the motor on undersized batteries.
There batteries equaled 48v total but there Amp Hours were well below the minimum requirements for that motor.
You can get a quick release thread for the transom tilt. If your battery is not optimal output you will not utilize the full potential of the motor. All jet drives reduce the power output even in gas jet drives. You lose 28 to 32 HP depending on your setup.
Place fish in the water, gently supporting the mid-section and tail until it swims away. Resuscitate an exhausted fish by moving it or facing it into the current, gently forcing water into the mouth and over the gills. Watch the fish when released. If it doesn't swim away, recover it and try again.
If it were me I would buy a Minnkota trolling motor that operates on 12 V. You can get one for $120 that has 30 pound thrust. I’m pretty sure it would go faster than 3 mph.
I have a minnkota 30 Endura that is the same spec as you listed above. I'm about to mount it on my kayak

So just tell you our boats are usually slower than jet boats jet boats are usually faster if you have the right stuff but if you could put the same motor in the jet boat and a normal boat or capella boat the jet boat would be slightly Faster by one mile per hour
But that's also thinking of a actual jet mode like an actual actual jet boat motor compartment instead of a Troll Motor chat so now I'm also thinking of like a yeah 8 cylinder they should all be somewhere in there
Awesome awesome something you could do just to look at it and take a like really powerful RC motor on it and shove it inside a Bare Bones outboard motor and just see what it does
Lol maybe I should have grabbed a paddle..and a couple life jackets might have been a decent idea 😬
Weird thought about not having “reverse” on old 2 cycle outboards the power head swivels 360 so you can point it to drive in “reverse “. Just something to try.
I had life jackets I promise! 😁
Those batteries don't have enough discharge capacity for full power, should have used an ebike battery
Batteries are way too small for a 48 volt motor. Look at the amp hours not just volts.
can you raise the motor so the intake is flush with back of boat
Don't feel bad I Bought the gas version you might go 3 mph lol it's sitting in my closet until I can find a small one person boat my 1957 duracraft had a 1975 Chrysler seeking 15 hp you could go maybe 20 and drinks fuel replaced that with a Yamaha 15 hp 4 stroke almost 30 mph and sir you are not Lying boat motors are not cheap 3000 for that 15 hp could just imagine some of them nicer bass boats with them 150 hp motors on them cost stay safe like the video
So virtually worthless lol. That thing is 2hp at best. Not a chance it's 5hp. For the same price you can get a 12 volt 65lb thrust trolling motor that can
1. Go in reverse.
2. Doesn't need 200lbs of batteries in series.
3. Weighs 1/10 what that motor weighs.
4. Is most likely faster.
5. Is quiet.
Get the out port above the waterline!
Run both at the same time 😉
Certified POS. But I will have to say it is amazing how you can buy this for less than a gallon of gas in the US right now. Build back better in every other country but ours!
Gas in more expensive in most of Europe than it is in the US.
If it runs off of electricity, it's a motor. If it's internal combustion, it's an engine
Motor=generates force, thus motivating a movement. Engine=two or more simple machines combined to work together to transfer force and movement to accomplish work. A pair of pliers are two levers combined to transfer force are an engine. An internal combustion engine is an Internal Combustion Engine Motor.
You can get a Minn Kota that performs better, in the same price range. A Jet boat is less efficient than one with a prop, as far as speed goes.
The 10hp electric HANGKAI model is listed as 60V 38A(rated current) = 2280w (rated as 2.2KW)
Whilst the 8hp electric HANGKAI model is listed as 48V 50A(rated current) = 2400W (again rated as 2.2KW)
What is the reason for the discrepancy? Is the 10hp model more powerful?
If you’ll raise the motor to where the bottom of of jet port is only about 5 inches below the water you’ll get more speed.
If a jet propulsion nozzle is too deep in the water you get very limited propulsion.
A short 10ft boat isn't going to be very fast unless he gets it up on plane, for that he will need more than 5hp. His longer boat probably was faster even though it was heavier. My 23 ft sailboats hull speed is around 6mph, pretty much no matter how much power. So yeah, that little 10ft isn't going much faster until he starts putting way more power than its rated for. Btw I have the same boat, kinda wish I had gotten a 14ft instead.
Yo what is with youtubers installing boat motors ON THE WATER!?!?! Also.........not 4hp!. 4hp is slow but not that slow! To answer ur question........are jetskis slow? And yes......English actually is hard if its not ur mother tongue.
god dude do you
you even breathe between words I don't think so how annoying
I bet your fun at parties!
Bree Anne you a Karen dude ?
That motor can propel you WAYYY faster than your experiment proved. You’re putting 4, 11 amp hour batteries in series to create the 48 volts the motor wants. So you’re using 48v DC at 11 amps (tops). That motor probably draws 30-35 amps at full power (conservatively). The more weight on the boat, the harder the motor works and the more amperage it needs. If you have a LifePo4 battery rated at 100 amp hours, you could go at least 3x’s faster. But those are expensive and I’m not sure if they even make one in a 48 V option. But if you got yourself four car batteries and put them in series you could easily get the amperage necessary to push that thing to its limits.
Batteries in series: voltage doubles (or triples/quadruples depending on how many batteries you use) and amperage stays the same.
Batteries in parallel:
Voltage stays the same, amperage doubles, triples, or quadruples).
You need more amperage!
100% know why it was slower. WRONG BATTERY AND CABLES. EV anything require amperage over voltage. You have the voltage. You even have the amp/hours available. The problem is the wires are too small. Those batteries, nor the wires you are using, are NOT rated for the high amp discharge required for that motor.
Image this. you have a car battery that needs jumped. You can't use 22 gauge wires to jump a battery even if the other battery is fully charged and brand new. Why? Because it can't pull enough amps to turn the starter. That's why jumper cables are thicker than the normal battery cables. It accounts for the net loss of energy in heat through the transfer from one battery to another through the cables.
In short, you need the correct battery and cables to make it work.
Ok.....but I'd rather go with a budget Chinese 6HP two-stroke....I have seen cheap mods on both the props and a homemade planing fin that improves overall performance.....easily moves one passenger on a small jon or inflatable at 12-15 mph with ALL DAY range. Both are toys but the 2-stroke seems more dependable overall
A jet drive on a small crappie electric or gas motor will never work good... I had a new 5hp 4 stroke jet drive and it was so loud because the motor is near your head... I Had a 10ft Jon boat with nothing in it... It was a joke... The jet drive design is plastic crap... I've only seen real jet drives on big horsepower motors cause you need the horsepower and rpms and a metal impeller n metal housing... Do not waste your money on that crap... I bought a new 2.5 Suzuki 4stroke...29lbs...$700 to my door and it's perfect for a kicker or small craft...
Your not getting 5 hp out of that. I had a 1-1/4 hp gas job and got more speed then you are. The math is 750 watts per 1 horse power. 750x5=3750 watts. Look at the specs on that motor and I doubt it is pulling half that. Find out the voltage rating on that, it might be 24 volts, if not look into battery AH output. Maybe a lithium battery with a high "C" rating will help but try and borrow one for they are super expensive.
Lead batteries with 100 ah are priced at 150.00 and weigh 70 lbs. LiFePO4 batteries at same level are 500.00, but weigh only 25 lbs. All Li batteries are made in china and some fail and there's little support past 30 days. With battery need a Battery box 100.00, and charger 30.00. Small Honda outboard with 5 year warranty is 1000.00. I chose the Honda engine
You should try one of those under $400. 12 volt 100 Ah lithium batteries on Amazon.

I have a 1.2 hp Gamefisher gas 2 cycle that would smoke that joke . You can keep your electric cars and boats .
Electric transportation anything is just a waste of money unless you have an electric golf cart to go 5 blocks to Circle K or 7-11.
The ideas are good but the technologies just won't be here for another 100 years. Societies will be fossil fuel celebrated until then, fill it up with +104 octane please!!
Please buy a 5kwh 48v lifepo4 server rack battery. $1.5k and it's 10 year 80% discharge rating eliminate all benefits of lead acid. Just caulk it heavily. If water gets in it becomes a giant fireball unlike lead acid
Not boaters apparently... You don't crack aluminum .. So seems few follow boating rules.. no wake zone automatic if boaters swimmers fishing in area at normally 50 to 500 feet ...
O.k. yes sounds terrific. I read a lott of comments and views and yes these plumbing pipes in the water really slow🤩you down. Lol. Cut a hole in the bottom on the boat and then put the jet part going out of the back of the boat now you can be a maniac and run over things. I would really ❤ to see you do that. As to the three bladed one replace the three bladed one with a two bladed one you can try different sizes and it will be more efficient so you will go a lot farther. That means battwry will last longer at the same speed. Rachel I think you need some new outfits.! If you are going to be on any more videos. Some people are just watching because of you. Get her sonething nice!!!! And she will jump up and down when you catch a fish. Lol
I apologize sir, I just got wound up and really worried when you electrocuted yourself live, and when you almost sunk the boat, or your questions about the effeceniancy of jet boats to props?? I don't know more importantly 'who cares'.
Have a good day bro I sory
Jet boat motors are way less efficient, so they take much more power to get the same output. This is just by design - they have other advantages, but by far the disadvantage is their poor efficiency.
My jet boat burns through ~$150 in gas every time I take it out. Fun as hell, but efficient it is not.
Well you said 4 or 5hp I just went with 5 so that's like 3750 watts so 78 amps at 48v and that was like 12awg I think I have seen those small batteries say they can do 100amps but probably not for long and ya like 12awg maybe 10
Mercury Thruster offers over 55 pounds of thrust, this motor is junk, 3 miles per hour sucks. My thruster runs 5 miles per hour and even it's to slow for main power. Good luck if any wind blows, you'll never make it back to the ramp. LOL
I looked for a but I can't find it. How does it take an Australian to tell you that a "jet boat" literally means impeller not a propeller. Imagine a hose shooting out water (high pressure,low volume) VS a bath with a fan ( high volume low pressure)
While you were using the correct voltage, you were only using 10% of the recommended Amp Hours to run that motor.
The motor was underpowered.
please start making reviews for these shitty china outboards, love to see you test the 4 stroke and 2 stroke ones
I would like to know the longevity of them. If they only work for a short time then they are not worth the cost, I have two trolling motors with about 500 hours on them and they are still working well but I'm looking for more power for the cost. You said that those are 4hp and a trolling motor with 55lbs of thrust is a little under a 1hp motor.
Sorry to say but your boating safety leaves something to be desired. Starts out with no paddle. Than no lifejackets (1 per person) . No throwable cushion. Batteries not secured in a proper container. No marine-rated fire extinguisher and no emergency signaling devices.
On a outboard motor, whatever the hp is? 30% is loss using a jet compared to having a prop! That's why river rats always have 60-90 hp on 16' - 20' Jon boats!
Next time, spend your dough on a dyi handbook for the "tool and physics challenged", aka: millennial, aka: I speak in errors b/ I literally don't know **it about life.
This makes no sense. If it had an intake poet like a jet ski you would lose a large amount of drag. I had a 5 hp Tohatso motor as a back up on my small 13 foot Boston Whaler and it moved that much heavier fiberglass boat right along pretty easily and much quicker then this. Jet drives are for very shallow water river creeks where hitting rocks or stumps are the reason a prop is too risky.
This is good for a back up motor you do need life vests and Paddles and safety orange flags and a fire extinguisher and a wisseal or horn boat tags an anchor anyway best of luck. GOD-BLESS.
$290 now. no reviews Also, I don't see how it's better than a much cheaper trolling motor.
I don't think that motor is a 5 horsepower motor. My horsepower would be more like 3.7 kilowatts. That would draw over 300 amps off your 12 volt battery when you turn it on top speed. That much current through those little wires would make something very hot. I think you should compare your motor to a 50 lb thrust trolling motor which is about the same as a one horsepower motor.
you sure are special.....lol I bought a 79.00 electric trolling motor from a big box store and a lawn mower battery for 69.00 that is probably 10x faster!
Nice videos btw
But your baterries only drains 12a you need at least 23amps yo get 1000w of your motor. Thats why you are half speed. Sorry my bad english
From my own experience of trying to learn and design impellers and props for electric motors, your impeller just might be poorly designed. More power may help, but you'll heat up the motor and it will degrade really fast down the road. I have a pile of them, because I am so hard headed. :)
Well, at least you got up to the speed of... smell.
I don’t know if anyone said this but 12v batteries on a 48v motor. I’m sure if you invested in a 48v e bike battery or electric lawnmower battery it would go much faster!
Comparing apples to oranges with both motors and batteries. A 40hp gas motor with a prop will get about the same as a 60hp jetdrive. as for small electric boats just go with a trolling motor an lithum iron battery . pro fishermen have bee using then for years, chances are they know
Grab a little RPM counter and see if impeller is hitting its rated RPM. could prob take off that silly "jet boat" housing and have a bare impeller that would work better.
jet boats also can suck stuff in and just get equally stuck on stuff personally I prefer propeller because jet puts out so much more sound and scaries fish more then say a prop but can you catch fish maybe but you also might scare more fish the only thing worse is a airboat terms of noise. I use a kayak 99% time i go places most people can't go doing alot marsh fishing.
I probably would have just disassembled that little electric drive motor, figured it out some kind of way the rig it up on a two stroke gas engine, give it a little bit more ponies, like 20-plus.
