you got a sub for the effort you take to get squeezed in those small places!!

[@carloscorona6649]

This is so awesome man keep going!

[@fredgonsalves7407]

Very talented young man. Awesome build.

[@seansysig]

The engine mounts will need vibration isolator bushings. Also the shaft will vibrate do to lack of balancing. I can't wait to see it in the water. Ir might sit liw in the water and might ve difficult to get up on plane. Life jacket & fire extinguisher for sure.

[@homemade_madness]

Yep it will sit low, but i dont think it will have trouble getting on plane, i guess we will see😁

[@2pi628]

@@homemade_madness Yes --- It will have NO problem what so ever getting on plane. I wouldn't doubt that the boat weighs less than the motor. It will be a rocket. Now All you need to do is add some foils and make it really fast.

[@JaccoProductions]

The drivetrain is really a masterpiece👌🏽👌🏽

[@bennybossboom]

Love the videos mate

[@lithiumike]

Nice! Lathe 2.0 and drill press 1.0! Looking forward to them and how this boat turns out!

[@democratsaretheDEVIL]

Great skills, ready to see if it can hold the weight. Definitely need to balance that shaft.

[@deborahworks6616]

Democrats are devils you are so right and may God bless you. I am Danny from Alabama this man is good.

[@Greg-io1ip]

I would have adapted the original frame, since you're cutting it apart anyway. But I also see how fitting your engine bay was necessary. Probably going to have too much vibration. I believe the frame has dampers built in. By starting with blocks in fiberglass at motorcycle frame mounting points, you could build the cover around that. Also: bidlge pumps mandatory. You're going to need 2. I'd not put a bidlge motor inside the engine bay, but I'd put a sump from each bildge inside the engine bay for redundancy, and ventilation for engine beyond the radiators outside the engine box and air intake. To evacuate moisture. But it's easy to sit on the internet picking plans apart while I'm eating donuts and drinking coffee.

[@Sawer]

Definitly gonna try that nifty hammer trick from 9:55!!

[@mxrider2strokebraaap54]

Ziet er heel erg goed uit👌😁

[@Youtubeforcedmetochangemyname]

This is a good idea I bet the flat four from the goldwing I have would make a good boat motor

[@lucasvanhamburg4937]

isnt that a flat 6?

[@Youtubeforcedmetochangemyname]

@@lucasvanhamburg4937 in the new ones yes it is but the one I have is from 84 so it's a 1200cc flat four

First thing you learn as an apprentice machinist is never leave the chuck key in the chuck so practice safe operations for your own protection

[@luanvdmerwe8257]

Strange how there is a "Yamaha parking only " sign against the wall but there is a Honda boat and super bike engine in there 😂

[@Mad.Man.Marine]

The spline on that drive can be found on any Chevy to borg Warner flywheel to transmission adapter for a marine velvet drive transmission. eBay has tons of them. It’s the part that makes connection from the engines flywheel to the velvet drive transmissions input shaft.

[@eddiebowens1919]

I love your lathe.

[@ABCustoms]

Lekker gewerkt weer! Ben wel heel bang dat de las op je tandwiel snel zal breken. Dat tandwiel is heel hard dus als je dat gaat lassen krimpt hij vaak kapot bij het afkoelen. Dus scherm de as goed af als je gaat testen zodat je hem niet voor je hoofd krijgt!

[@homemade_madness]

Hmm ja goed dat je het zegt!

[@Mad.Man.Marine]

Also. The way to do this with a street bike is to build a tiny Areneson type surface drive. It would be ten times lighter and faster.

[@homemade_madness]

Well go ahead🤷🏼‍♂️

[@Supercarlsunday]

Nice twin pipes..

[@mikehoefer1827]

What kind of eye protection do you wear when you are grinding?

[@tonya9614]

That driveshaft is beefy!

[@watahyahknow]

drillpress can be found on marktplaats for about 20 euro so just buy one as for fitting the driveshaft (length) i wouldve slid the engine back untill the ends fitted , eazier to get replacements that way

[@musicalcem]

jetski turbine instead of the driveshaft would have been lighter, easier and more powerful no? Awesome project by the way, how are you gonna deal with air cooling instead of water cooling? thanks man for posting keep it up👍👍

[@homemade_madness]

Yea i know, but couldnt get my hands on a jet drive. Just gonna keep it air cooled with the radiators

[@santicarracedo2831]

Nice job dude! 💪 Greetings from Argentina! 🇦🇷

[@eieio6641]

Is it possible to off set the motor or mount it at an angle to lessen driveshaft angle??

[@MakarovFox]

that a big joint pice

[@klutchkitty2114]

What Honda model did you get the motor from

[@fredio54]

So you DO speak English decently well, a lot like all of my other Dutch friends from IRL, same accent, too :-) Any vibration from the unbalanced shaft spinning flat out? You could have got lucky but I'd imagine some subtle rumble would be coming from it, or worse :-D

[@timhurkmans3788]

[@barrymayson2492]

Hi hate to negative but the vibrations from that shaft and fixed engine mounts may be a bit fierce!

[@Globalnomadsj]

What kind of welding are you doing for the frame? Arc?

[@homemade_madness]

Mig/mag

[@nidzdotnet76]

That CV shaft joint won't last very long on that angle... Ideally you want a cog and make the drive shaft straight.. Less resistance.

[@TheBossKelso]

[@alexanderbisson1819]

Dont grind with your arm over the grinder shield or in front of it on this video. Thats how i cut ky wrist by accident when it jumped to my hand

I think it would be a good video, if he would have talked instead the distracting noise, called music. All these people get into making a video are getting their music way to loud .

[@mayamaya2068]

Yoga Lathe lovely

[@baenkt]

Cool project, but that stern drive sits way to low. I mean way, way to low. But you are very talented, so I wouldn't be surprised if you build your own Arneson drive instead... And please don't listen to the water jet suggestions ;-)
