Honestly at this point I wouldn't be surprised if the Solar Wings will double as partial ground effect surfaces.

Your evolution as an engineer, video editor, and project story teller, from early days of flying planes around your parents yard to electric boat admiral, never fail to amaze me.

The boat looks fantastic, I wonder if there’s interactions with water turbulence or if the pitch is too high for the current speed of the boat causing a little bit of vibrations. Maybe try adding those small outboard hydrofoil/anti cavitation plates?

Your youtube journey has been phenomenal, Daniel. That's a lot of hard work, but great to see you enjoying the fruits of your labour's. I can only imagine what the typical, "how much range does it have?" Bystander would say about a 3d printed drive train with autopilot. You crack me up. I love your boat too.

Nice project. Maybe if you are worried about vibrations damaging servo, you could think of some tpu damper between servo horn and linkages, so it isnt stiffly coupled. Looks like it wouldnt affect precision of steering in any measurable way, but could dampen those vibrations.

Them rubber rings are usually impact protection. It's also there for harmonic Ballance on the motor shaft.

Loved that ending! “All in the same boat” is some of the best work featured by Pat Riley on this channel.

I've been following you since you were flying crappy foam planes out of your parents upstairs window. Your journey continues to amaze me and I can't wait to see how this project evolves. Amazing work sir 🤘

That rubber piece in the prop is called a hub. Should you kit a rock, it breaks from the splined shaft to save the lower unit (gear case) Also, you should crimp the battery cables lug.

Love your nautical adventures, Daniel! I absolutely love that you get in over your head on projects but always power through -- that boat project looked like a nightmare and you made it happen. I bet it feels good to be in it!

The rubber in the prop is a safety point that can flex if you have a prop strike. Pretty standard on boat props.

I'm absolutely in envy of the gorgeous area of Washington you're in and the time/ability to work on so many projects. Thanks for sharing your work with us. I'll live vicariously through these until I can finally move out west

I am in awe of your motivation. Thanks also for showing the fails along with the wins. I’ve got six months of a few hours a week working on a large 3D Printed Project. I’ve hit the Meh stage. Your videos are helping to restore my motivation.

Love how you have original music in your videos. Its always one of my favorite parts.

Just a tip on set screws on shafts is putting a dimple on the shaft with a drill bit , tighten the set screw and then run another set screw on top of the first ! It’s done in the heavy equipment industry all the time and never fails !!!

Dude, I’m so impressed with the quality of work and engineering you used to build your boat. It’s unparalleled on RU-vid thus far. I will say, you might want to consider simplifying the mechanisms and linkages to make it easily repairable on the go. I’d also recommend a PWM between your battery and motors as it will reduce the amp draw on your battery over time, since motors generally use higher amps than they convert to power at lower speeds, and the remainder of the energy is converted into thermal energy. A PWM will mitigate that issue considerably, increasing effective range by about 20%. The other thing I’d recommend is having a couple small Amazon kayak sails for $20 (the kind that looks like a circle). They only work downwind, but in the event of a motor failure, you’ll have a way to get back to the boat ramp without breaking too much of a sweat. You could also install some dual purpose oar-locks for rowing the boat, or use them to hold fishing poles or GoPro mounts. You did great in designing redundancy into the systems! Definitely get a waterproof laptop for the next voyages! I was terrified for your Dell watching this video. Especially if you have any important data and calibration software for the boat that might make it unusable without it. You have to name it! Name idea: Arr Sea 🌊

I love your 3D engineering. It all looks a bit over built but it works. Happy sailing.

So glad to see you went this direction. The magic of RU-vid for me is watching someone else work through very similar ideas to what I am working on. I can attest to the resilience of PETG (mine connects the motors to the boat’s helm). It is not underwater, but has been in all the elements over the past three seasons.

Awesome project. Get some lifejackets dude.

Your videos have totally inspired me to do the same thing. I bought a big ass LiFePO battery and a trolling motor and built a frame to mount it on my inflatable canoe. Spent the summer cruising the waterways in my country every few weekends. My build was much less DIY, I just shilled out the money for ready made parts, since I don't need autopilot or stuff like that. Cruising around the waterways is the most calming, satisfying thing ever, highly recommend. Thanks for putting out these videos, they're always a joy to watch!

What an awesome project dude! I can’t believe how fast you model and produce parts for that thing. You say it’s the 3D printing that is the magic behind the rapid prototyping, but I think the magic is how insanely skilled you are at coming up with a design in your head, adapting it to use the parts you have on hand, and then putting it all together into a creative solution. Well done sir! 👏

You need the rubber grommets on the servo, not the props. This is awesome. Next, a full on EV speedboat.

After watching both of these videos about your boat... It makes me think your favorite hobby is sanding... You did a lot of sanding bro. Good job! Looks dope

I work a lot with pixhawk flight controllers, it's best to do your gyro/compass calibrations away from large concrete and metal structures, and it might also help to place the here2 gps puck on a small mast somewhere away from other electronics/ sources of EMI. Awesome project, waiting for the next video in the series!

That looked like a lot fun in the sun 😎 All the days and days of hard work finally paying off. Congrats 👍

I’m so hyped for more of this, I love seeing all the tidbits of how it performs and the problem solving! You pack into a video in such a nice way too!

I grew up in Seattle on lake Washington, swinging on that exact rope all summer long. I always dreamed of building a powered boat to launch around Fremont, never really happened. But i can live vicariously through you, watching these videos makes me very happy. Thanks man!

And now the song is stuck in my head. Glad we are all in the same boat. Thanks for the great content!

Hey there! I see you have two of the same props on there. Turning the same way. This might increase the propeller walk (also known as propeller effect, wheeling effect, paddle wheel effect, asymmetric thrust, asymmetric blade effect, transverse thrust, prop walk). You won’t notice this much when going forward. But when going backwards this might become an issue. If you have 2 props. You need them both turning different ways to counter this effect. I love the project so far! :) it’s amazing what you do. Keep it up!

next project: Autonomous Airsoft Close In Weapon System or A.A.C.I.W.S. with Airsoft minigun

This boat and your overall effort are impressive in so many ways. Old mariners like myself believe there is only one right way to build and repair boats. And that is usually true. Things like galvonic corrosion and wind can easily be overlooked by newbies. That being said you did a good job applying new tech to old school boat. I really hope you give those motors a chance at recommended voltage and 2X the recommended amperage available. I know...expensive controllers and batteries! I actually love the batteries you have, you just need more of them. Once you have all that power you truly appreciate the motors you have. Tiny props spinning like mad, low amps at any speed, and a displacement hull flying on the props. Sounds like fun to me. I have faith in you. I'll check back later.

This is my favorite channel. All these brilliant R&D creations near my old home

I don't have a ton of powerboat experience but I would attribute the vibration you observed to cavitation. Cavitation is inherently chaotic and will cause differential thrusts and vibration. It's hard to see if that is actually the issue, but I know it's an issue on every RIB I have driven

I expected your channel to have a bit of a lull over the winter, esp. the Boston whaler series. Here you are again fueling my procrastination and keeping me up late. I just cant help but watch every time, its so damn interesting. Cheers from the olympic peninsula, keep crushing it Daniel. Oh look! Stuff Made Here has a new vid too...

Finally a good song! Awesome project!

Nice job! This is what it’s all about, taking a project boat, your imagination, tools and skill set, and challenging yourself to make something that can be used and enjoyed for exploring. Once you go with differential thrust steering it’s hard to go back to babysitting a tiller or wheel. Really enjoyed the scenery as you cruised about in these videos. Looking forward to solar integration and bigger motor controllers to see what those E-foil motors can do pushing that hull.

Need counter rotation props.

Thoroughly enjoying your 3D printing here of big bulky parts, it's a world away from my tiny designs which work with the 'grain' of printing for strength, efficiency & printing speed. My "Hoopin TPU Cable Tie" is perhaps the strongest cable tie design on Thingiverse, which was created by accident, I photo'd my Prusa hanging from a normal size print to show its strength.

This project is the thing that got my attention to your channel, but your engineering is what made me subscribe. Tying the motors together with tie rods and ball joints is the answer I was looking for for a minicat project that I am planning. I have been considering different ways to have a dual motor setup, using the motors for steering. Great work on this project, can't wait to see the next part.

I would love if you started doing more with bigger boats, this project was incredible to watch start to finish, that boat looks fantastic! I'd love to see you make something this size with some power in it.

I would see if you can find some counter rotation props for it. Also an adjustable jackplate could help tune the height of the props in the water. Awesome project!

Don't eat bat soup guys

We live in the UK but have relatives in Shoreline, the slipway you launched from was the one the Duck Tours used to get into the lake. Happy memories of Seattle watching your RC escapades!

Can't wait for the homebuilt props video!

Hey man, just as a friendly chunk of life changing advice… get an impact driver, absolute game changer

I love your boat, too. And your videos. Thank you for a very enjoyable half hour!!!

For props try using 8" (or so) RC Airplane "APC" brand pusher propellers. They work extremely well and are much more efficient than a typical boat prop at these speeds due to their long aspect ratio.

Dude, the smile on your face as you pulled away from the dock, lol. So much work went into this. What a journey.

Congratulations - brilliant project and video as always. 'Wobbly path' on auto missions is going to be a big hurdle, so I'm really keen to see how you tackle that issue. Well done again.

Great video, as always. Maybe try a little K.I.S.S. Rigidly mount the motors to the boat (and use differential steering if required). Add a tradition rudder/tiller (with a linear actuator for automated control) for manual/backup steering. You could make a linear actuator using 3D printing, threaded rod and a nut - or CNC it all in aluminium for strength/precision. Stay safe out there.

I've been watching your videos for years. And it's interesting to watch how you projects, engineering skills and your knowledge has expanded. Going frm small projects to bigger projects. Wel done and keep up the good work.

I'm surprised that servo didn't come with a keyed shaft, would've held up far far better than a grub screw! Great video as usual!

Adding a Cooling Fan to your Electrical Box wouldn't be a bad idea to keep everything cool. Along with a Rubber Seal to minimize moisture build up within... SWEET WHALER! Can't wait to see what you do for an Operator Station on this with a Windscreen, Steering Wheel and an Emergency Radio for that "Pooh-Pooh Happens" moment...

Make sure you have your 1 pfd per person on board + fire extinguisher, coast guard don't play... I'd have a throwable too, but

Love it! I decided on differential thrust so no extra moving parts are required, but a 1 motor out situation is pretty likely, so ya got me thinkin I should be able to manually offset the angle of either to get close to straight thrust, and steer with an emergency paddle

That was fun, thanks for giving me a ride in the same boat. You've inspired me to continue converting my gas powered boat to electric.

I could listen to Daniel commenting on random boat all day

After watching your videos, I feel like anything is possible. I started the day feeling lousy, and now it’s all good! Bless you.

Man, Daniel… you killed it with this project. So much hard work and ingenuity went into this and it shows. I hope your parents are proud of you, because if I was your dad I would be bragging the shit out of you to all and sundry. Well done.

Am heavily into rc aeromodeling to the point of flying my first turbine for a little over a year now having been in the hobby for a bit over 42 years. LOVE the way you did this latest project and you most certainly have a lot more knowledge on how to do things than me!! (Although google and you tube are pretty good friends!!) Look forward to the next video from you.

Most underrated YT channel! Amazing work.

That's awesome. I used to live in that marina right next to where you launched. It was great to see the old home waters, thanks a bunch.

I say ‘bravo’ for a job well done. You really saw this project through to fruition!

This is amazing! You could static balance the prop just like an airplane prop. Would make a cool 1 minute segment. Also skim coat all the wood with resin, it’ll keep in in great shape for a longgggg time. Or soak in wood sealer for a few days. Always looking forward to your videos!!

Really top quality fabrication in this project! Very well thought through and designed.

It's great watching Daniel enjoy the rest of the Summer now that it's December.

man I love watching your videos...its always a new adventure. I know I'm on the other side of the world but it feels like we're all in a cool trip with how good you produce these videos like a cool little story

What a lovely person you are and how lovely are your songs! Thank you! ❤

The rubber part in the props is the hub. It’s made to absorb pressure, light impacts and dampens harmonics. The gap between the prop and motor is what is causing your vibrations.

The level of knowledge you possess literally blows my mind. Keep it up. Love the content

This is so cool to see because I have the exact same boat, but with a 8 HP Yamaha two-stroke engine, and it's cool to see the potential of "my boat"

Just an FYI, you can find those chunky servos in overstock at princess auto if you are lucky. Built many RC projects by harvesting motors and gearboxes from the overstock parts bin for like $7 a pop.

It is a great looking boat I'd give you a high five. You did a fantastic job on fixing that boat up and making it fully functional.

"Contemporary Grunge" I love it!

This has been really cool to watch! I would definitely appreciate some kind of Q&A about the project. You sound like you've accumulated a lot of knowledge about it!

Really nice closing segment. All in the same boat.

Welcome to boating on hard mode. My grandfather was building rc sailboats back in the 60s, using tiny canvas sails and strings wrapped around servos. I, notably, have not taken up the same challenge lol. You do need to know the local wind direction and speed, which can be accomplished low tech with a nylon string (something heavy that won't kink) attached to the top of the mast. Like a wind sock it tells you direction and speed.

Love this project. I'd recommend staying away from structurally loaded PLA parts. Stick with PETG or other higher temperature plastics. I've had PLA parts warp when left in direct sunlight outside. PETG gives you around 20C higher temperature tolerance from softening than PLA

This video is fantastic you've taken an idea I've been casually thinking about for a while and made it real! Your work is great, videos are fun and always love the music you add / create. Keep it up!

just pointing this out, for printing solid parts, its usually better for you to have a few walls and solid infill rather than all walls, it will print faster, be just as strong, and wont have any gaps where there isnt enough space for a wall(wont make a difference for really big parts but its waaayyyy better for smaller parts).

This is just an awesome project - and I love that you shared the enjoyment of the end result :)

The rubber bushing is not a self centering feature - it's to protect your lower unit gear/engine from breaking when you hit a rock. Idea being that the prop starts freewheeling on the bushing. Before the rubber bushing, you would have shear pins.

As much as I love you're projects I think I love that you make you're own music for them even more. Please don't ever stop doing that . I literally watch all the way through hoping for a song lol !

A primitive water cooling system might be good to have for the electronics (tiny water pump, copper tubing in contact with electronic's heat sink surfaces)

Thank you! I am trying to make my 24 ft. pontoon boat all solar / electric. You have given me a lot of great suggestions.

Yay, I was waiting for part 2 ! Thank you. Happy Holidays Daniel.

Fantastic project and man your dedication in part one to solve all those glass issues you are one persistent ***** LOVED IT THANKS

This is a great mixture of ingenuity and music. Big grin inducing Thank you for your efforts / Ed

It would be really cool to see you try to recreate something like the yamaha joystick docking system but that would mean adding independent steering on the motors.

Just a tip the best way to epoxy something like that is to use a spreader, wet through the back of your cloth then use the spreader to apply it to a wetted surface. Another tip, you can use nail polish on your electronics for protection then pot then in epoxy with the wires connected. That rubber piece is designed to shear after it gets a high speed jam, like a line around the propeller. It breaks instead of the crankshaft

As always Daniel your videos are really inspiring me to make new projects. Awesome video, once again. Thank you for sharing this adventure!

Really inspiering video! Love it. :) My first reaction to the propellers was "those are huge!" I think to get more power out of your motors you need to use smaller propellers and higher RPMs. When you make your own propelles you should allso have them working in opposit direction, to counter out the yaw from the propellers.

Too much fun to watch your process. You are a gift.

I love this!!! I have been dreaming of doing the same thing to a kayak with 1 motor. Might have inspired me to start

Since you have 2 motors you could do azipod steering that big ships use. You can go sideways, turn inside your length, etc.

Very cool! Reminds me of my own hydrofoil project with the same motors. Back then I wished I had just used a bigger diameter motor out of the water for more torque.

man you do a good job of showing just how much work it takes to build these things. keep up the good work!!!

14:00 sick battle wound bro 😎

for the interested: the rubber in the prop hubs' main job is to reduce wear in the gearbox on regular outboards. when you shift, you are smashing two flat pieces of steel together in the gearbox (driveshaft and propshaft get connected through the clutch dog), where the driveshaft is at 7-800rpm (or more), and the propshaft is standing still. getting the propeller up to that speed in an instant is not so great for the clutch dog, so the prop hub is isolated from the prop with rubber to dampen the blow. it also takes out some vibrations at low rpm, and help a little bit if you hit something, though they are not meant as shear pins. your prop will still break off all the blades and bend your propshaft if you hit something big. you don't really need those rubber inserts here, as the power delivery from an electric motor is smooth, unlike in gas powered outboards, and you don't have a shifting gearcase.
