- the first test drive of my speedboat project! it worked pretty good, altough i do want to make some changes as you can see in the end of the video.
She definitely has enough power though! (120HP) Very fun to drive, with a great sound too.

Check out the second testdrive in top gear, i went all out making the video, it turned out amazing!

A front spoiler or perhaps some sand bags would go a long way towards keeping the front end down.
"Practical is boring". Me and you think alot alike. Love the video
Incredible build I must say thats a work of art. Driving a boat like that shift gears must be fun lol
That outdrive is slowing you down. Straight inboard, shaft prop and rudder. Much Better...
V2.0 v drive
@@prtyof4156 Jet drive would be better for shallow water.
Surface drive....
Leave the link to the one that you built??? 🙄
@@justincasey_grabbederpussy6756 he’s not hating he’s giving advice
It might be to your advantage to buy a used personal watercraft as a jet drive donor, I would keep the motorcycle engine setup, but have it run the jet drive instead of the lower unit. The jet drive will weigh less than the lower unit enabling you to achieve smoother acceleration and higher speeds on the water.
Exactly what i was thinking. I assumed it was a jet boat until I saw the goofy huge outdrive
Cleetus McFarland built a jet boat

You actually lose a lot of power with a jet drive. With outboards a 150hp prop drive will be rated as 115hp jet drive. Same motor.
@@grizoh You're absolutely right. Propellers are substantially more efficient than jet pump impeller drives. They both have their pros and cons though.
Really neat little project. That drive is really deep though. Its slowing you down quite a bit. A jet drive would probably work better since it would push more directly on the back of the boat instead of 20" below.
I concur...it’s also providing some scary handling characteristics and in the right situation could cause the boat to porpoise and capsize.
That looks like too much fun can't watch without smiling
That alignment is mint 👌🏻
That thing looks amazing to drive nice!
I've been waiting for this one!!!
Nice cool having the gears to change through!
gets on plane quick....good job man.
Its an awesome build! Love the idea! And the cv joint takes care of so many engine/sterndrive problems. But I hate to point out your leg is too low, the planing plate of the leg should line up with the bottom of the boat, or even a "c" hair above the bottom on a fast boat
Nice build, But I think U missed something 🤔🤔🤔🤔 First testdrive-homemade-on Water 🤯 Life jacket!!!!!
Awesome build MAKE SURE YOU CHECK THAT STEERING BOLT EVERY TIME mine fell out last summer going 35 and the boat went full left and almost flipped and ejected a few people lol
Or just weld it and cut it off if you ever need service
Love it. The drive is 1/3 of the size of the boat!! Great stuff!!!
This was so cool, it worked soooo well!
Thank you! I love your videos!
That Penta is not really made for RPM but, you can still dial it in using a prop slip calculator. You plug in gear reduction, RPM and Top speed and it will tell you how efficiently your propeller is working.
From Canada here, awesome that you have made all this work! Most North Americans are not willing to do this amount of work, but I am! I do crazy fun projects as well and think this is awesome. Lazy ppl that dont build their own stuff will criticize for not spending a fortune on everything but i love this! Keep up the adventures! New sub from me
Just brilliant.
That’s an awesome project. Be even better if you pretty it up. Thanks for sharing. 👍🇦🇺
Excellent build
Thank goodness that boat dolly didn't break while under such a load!! Nice work young man!!
You’ve build a dune buggy,a boat now a air plane? A mini bike would be cool or even something with tracks!! Love the vids
Im planning on building a new buggy🙈🙈 😁
Have a look at the channel rather b welding he makes cool dune buggies
@@homemade_madness ooooh cant wait to see that video!
I vote for airplane.
Wow answers a lot of questions. Don't stop looks good to me.
Yeahh😁😁
Bloody fantastic
14:35 "Didn´t sink...well...that´s important"
You´re hilarious xD
Nice work, looking forward to the next video mate!
Hahah thanks!
pretty sick build there!
Cool!good job 👍
Very Cool!! Great Work!!
Dude you're so awesome!
Wow! You’re a genius, did you figure this out on your own Einstein? You’re quite the detective. You figured out how to steer a boat. I’m just dumb founded at your brilliance.
This thing is awesome !
Thankyou ,, been waiting for this video ! You made my day :)
What a cool project 👍
I love how you left the transmission.😁
great build, I think when you go to fix the cv joint with the chain idea gear it up so you can get a better top speed
Well done!
very neat great job keep up the good work
good job, the new drive will help a lot, i did not notice a bilge pump? are the waters around you shallow enough for a recovery? if they are deep i would suggest you fit a pump, its to good a project to see it lost.
Bro you should use an aftermarket exhaust it would make it sound really cool hahahaha keep up the good work! I just found ur channel and i just subscribed!!!
🤣🤣🤣Travel Lift for that tiny boat ...awesome
You can also have another gear ratio to play with your plan of straightening the drive shaft. Then you can dial it in for like a 3rd gear take off with the light weight boat. No need to start in first unless ur stern drive gearing is heavy and cant get you on plane quickly. Awesome fun project, i look forward to seeing more. I should share the crazy thing im doing in Ontario Canada.
Awesome. Thanks TH-cam for suggesting. Even the title looked like a good idea.
👍👍 Towards the end of the video when you started shifting gears👍👍... I am a subscriber now. Don't over load that gantry lift 😁. Great work
well done looks great
That’s crazy bro . At first it looked like it was going to do a wheelie on water, then as it picked up speed it corrected itself and became a beast .😎 you are very talented my friend. The test drive Must’ve given you adrenaline rush lol . Keep up the good work 👌
Yes spot on
Wow! This is my dream project
Yo those dual exhaust look bad ass 👀😎
Second thought outdrive might be good seems to ride correct
Great job man!!!
A very nice boat that you have built. A nice little runabout that's good on fuel and it's fast. Music, not so hot.
You are welcome.
You should turn the engine at an angle, not square on, that will give you much less angle in your propshaft to the stern drive.
@Daniel B
Correct and a guard covering the whole incase one end or the other let's go .
Subscribed, very cool man
Looks like fun
Nice project. Trim tabs will allow you to keep the bow down at speed. That is a huge out drive for such a small boat. Is this a case of that is what I had so it is fine? Thanks for sharing
Fantastic series thank you sharing. Having lived in the and on the water a majority of my life.....please consider the addition of three items:
1) Bilge pump.....if you inadvertently take on water the ability to get it out is imperative.
2) Fire suppression.....fire onboard is catastrophic.
3) PDF / life preserver
Again..... thanks for sharing.
This is the first boat I’ve seen with a transmission, sweet from Cali, USA 🇺🇸 👍👍👍
What you think big off shore cats run with chopper engines run 2 speads
Stellar job mates keep it up ❤️👍🙏💕🌈🇲🇾🤗😎
The outdrive is hanging way too low. You have to lift it maybe 10 cm or more to get max speed.
Althoug your completely right, you gotta respect the hustle
Respect, goed bezig
Mooie opmerking ,little play in the steering
Nice build👍
Please put a jet drive in that thing . Looking good 👍 keep it up
Very cool I love boats and to work on them. Have you considered using a CVT transmission like the kind Polaris uses in their quads? I am sure you could fabricate any necessary brackets to get it to work.
Super cool 😎
Good job perfect
This does give me an idea - Take an older Yamaha Waverunner (running project boats are readily available for $1500) - it already has a marinized superbike 160 hp R1 engine, remove the upper hull, remove the front flotation block and move the gas tank to the back. Put a seat in front of the engine. The FX HO hulls are almost 13 feet long - Should easily hit 70 mph stock with the weight removed and a slightly repitched impeller.
Make sure that outdrive isn't too low in the water. The top water intake hole should be inline with the lowest part of the hull. I couldn't tell if you had a whale tail on it, but if you don't you might consider it as it improves turning, efficiency, and time to plane. As far as the jackshaft idea goes, I like it, but personally, I'd move the engine back before doing it. Then again, I don't know much about boat weight balance, or that of this particular build, just that most boats have the majority of weight in the rear half.
I know its too low. I like to keep the engine forward ad much as possible to keep the weight in the middle👊🏻
Great stuff !! IF you straighten that shaft out, much there better.
AND with a new prop and a "trim" to facilitate planing, so much the better.
Speed is not your problem.
Very nice love it

Goed bezig! Hij is wel echt snel😂
Pretty cool kid ! 👍
Hmmm,a superbike is made to switch 7 gears very quickly when accelerating,but a normal outboard has only 2 gears(forward and backward)but if you stick to long in one gear with this superbike engine you might blow up the engine.But this is a very interesting project!
Nice build. Id do away with the sterndrive and go I/O or Jet Propulsion. That would help eliminate drag from the outdrive but either way its pretty cool!
Great idea to have gears. Ever looked at a jack plate on outboard. Idea is to have prop half way below bottom of transom. Move x dimension up and back. Stainless prop will have less deflection more top speed. 4 blade is hole shot 3 blade for speed. Jet drive you will loose speed.
Should of went with jet drive. Les problems and lighter. 👌👌👌👌
Great job :)
Awesome build man !! Die i/o sterndrive die zorgt wel voor een hoop weerstand. Zou mooi zijn als je er een surface-drive (arneson) van kan maken.......dan ga je NOG sneller 😉😄😄
Echt geweldig!😍
For the cooling system, get a water to water heat exchanger. You use coolant in the engine, but it is cooled with a radiator in a tank with water flowing through it. They are used in “closed cooling systems” on many boats.
Great 1st try
Awesome...
Very cool
When doing that chain set up I would increase the ratio and a metal plate on the hill so if chain ever breaks
Nice project
Upshifts on a boat would sound amazing with a H2R motor swap lol
You should put in a massive jet drive!
Sick
Echt super vet gemaakt man 😎👍
Pretty sure a lot of jet skis have more hp than that but still really freakin cool
That really depends. A jet ski can have 50 hp but most jet skis are about 100 hp. Crazy expensive 1s with superchargers have like 250 hp.
Some built skis have around 350 to 500 horse. The thing that they lack is a 6 speed manual transmission gear box that a bike engine has. That changes the drive ratio of the turbine in the jet propulsion system that sucks the water from under the boat forcing it out the rear. That's wear the gain would be with a bike engine the only down fall is bending the drive shaft unit to that propeller in the the turbine resulting in catastrophic failure and possibly sinking the boat. If I remember correctly the best way of getting more speed is changing the pitch of the prop killing lowend but gaining topend if the engine has the torque to compensate with any type of boat engine you dont really need the hp your more after the torque because water is denser then rolling a car down the road.
@@uglyfxxx6981 supercharged are 300 these days.
Eerste zin hoor je de nederlander😜goed gedaan man mensen die zoiets maken kunnen we hier meer gebruiken!!! Hoop de blauwe kakkerlakken je beetje met rust laten
Thank you for this nice video, just keep safe sir...
Very nice 👍👍👍👍
If lighten drive shaft and just run straight prop it be a lot faster and move fluid, great build
Really cool build but the drag must be insane with the drive that deep in in the water
It looks worse than it is😁
Danger! Peligro!
I’d do a overdrive with the chain so you don’t have to shift. Since it’s a jet pump you want it to not be able to rev out all the way and hit limiter you want the pump to load it hard enough where it can’t over rev
