kudos y'all. Plumbing? Check. Electrical? No problem. Carpentry? Yep. Paint and finish work? No one better. Sailing, photography/videography, graphic design, and problem solving/engineering? Y'all knockin' it out! Keep it up and stay safe out there.

Dear Kiki and Dan, I’ve been watching a variety of your adventures in different order. But now starting from the beginning! This one has me shaking my head in amazement!! Being architects must be a serious advantage. But all the wiring, battery knowledge, electric motor finesse put together is in my view a thing of beauty!! You are already most of the way to being true sailors. Namaste!!

You are making so many thoughtful refits to your boat. It is lucky that you are both so handy! It will serve you well with your boat!

You guys are so cruel! The anticipation is killing me. I wanna see that boat prove everyone in the Marine industry wrong concerning an electric powered boat. This could be REVOLUTIONary in the way props are turned in the future! I applaud you guys and look forward to every episode. Cheers (and and can't wait to say, safe sailing)!

I do admire very much not only ingenuity and craftmanship you show at refitting your boat, but also how you are able to work together. Not every woman wants to share all the hardships of such work. I have been always dreaming of what you are doing now, but due to political and economic reasons never was able to fulfill my dreams ( majority of my life I spent under communist regime). I enjoy very much watching reports of your adventures. I wish you happy sailing through life together.

I knew about your KZfaq channel from the 'Bootsprofis'. They naught an electric motor ready for their vessel. That you are constructing your own is simply great!

I have watched a lot of KZfaq builds and yours are as good as I have seen. Because of the virus I am binge watching

The person who told you that it was a "Sea-Pex" motor didn't know what the heck he was talking about! It is a sepex motor, short for SEParately EXcited! It means that the stator and rotor windings get power independently of each other. This allows a great deal of control over the motor. Basically, the amount of current through the armature (usually the rotor) controls the overall power output. The strength of the field windings (usually the stator) controls the torque and counter emf characteristics. Essentially, the armature current can be thought of as a throttle; the field winding can be thought of as a transmission. To a point, more armature current means more power. A strong field means more torque at low RPMs, but limits the top speed. A relatively weak field means higher RPMs, but less torque. Since both the windings are separated, the currents can be changed on the fly, and a good controller can optimize performance at any speed.

”Life is one big party when you're still young But who's gonna have your back when it's all done” What an great, organic version of “Angel”. Bradley got song! This channel is full of surprises 😊 😊 😊

The electric system looks great! I just read elon musk's book and his vision to take on the auto industry by making electric cars. And he did just that. I hope you guys are starting the same trend towards boats. Boats add solar, wind and hydro energy already, why not have it power the engine. And who knows maybe one day in the not to far future lithium ion batteries will be able to be used on boats. Keep up the good work, it's very inspiring!

great job on the electrical system for the engine. i am an aircraft electrician by trade, and your wiring is done well enough to go on a aircraft. good attention to detail, and high quality work. keep up that kind of maintenance, you wont have any problems with the boat at all. looking forward to all your future videos.

Good singing and guitar playing at the end he was very good at both

There is a product called a commutator stone for seating the brushes and cleaning the commutator bars. This is used without removing the motor. Also you may want to figure on having a source of compressed air to keep the motor blown out as the carbon dust from the brushes can cause shorts in the motor. That is a pretty common set of brushes but you may want to keep a spare set. As soon as the brush wears even with the top of the rigging they need to be replaced. The lower in the rigging the brush gets, the less spring tension there is on them and it accelerates the wear from that point. A good rule of thumb for maintenance is 250 hours or every 90 days. Until next time fair winds.

Your vids are the best on KZfaq .. OMG you guys rock.. hard work and smart work.. realy good edit of video Funny and nice to look at ..

I'm really enjoying your salvage and built ethos, in Hot Rodding it's called "Built, not Bought" , well done!!

Just discovered your project/videos from Sailing La Vagabonde channel and I spent most of my afternoon watching all the vids and reading the articles on the website ! Both your project and realisations are awesome, real dream makers ! Also, for people liking "tech stuff" as board repairing, DIY and optimization, your vids are really interesting ! Carry on !

What a great episode. I’m watching all your videos. Ur so both very talented.

You two are brilliant!

OMG! Halarious that you used that song in this! i can't wait for you guys to get back from Mexico and hey that prop turning!

WOW! Impressive!! You are the only youtuber that seems to be tackling "real projects" and you are really smart about how you do them!!

Your best video so far, in my opinion, of course. Liked the black & white portion and the live guitar at the end.

It is all coming together quiet nicely you guys ! I'm really glad you decided to go with the electric motor because I had talked about doing something similar for a houseboat. I worked as a golf and turf specialist for years, so I was around golf carts a lot and got to go to Club Car factory in Augusta Georgia. Real impressive and the best cart on the market in my opinion. It could go 36 + holes on one charge with 2 fat guys and their clubs ! LOL I was going to use 3 banks of batteries so 2 could be solar charging as 1 was being used. I also was going to modify 2 heavy duty trolling motors as bow and stern thrusters for docking. Its not like I was planning on skiing behind the boat or anything, I just like the idea of clean, quiet reusable power. And the houseboat could just drop anchor if it needed to be charged where a sailboat could just continue on its way ! Great job guys and I can't wait for the sea trials ! Fair wind and sunshine to ya both !

What will you use for cooking? I went to an Origo/Dometic spirit stove as like you I'm brushed DC. Sparks and gas (not American Gas!) don't mix. Also suggest a collar on shaft to stop the collar of the PSS seal being able to slide if the grub screws come loose. I also tapped the end of my motor and prop shaft M8 and used penny washers to stop either sliding out under load, which could happen surfing down waves. Fun watching you doing it all. Takes time eh!

You guys rock! This is the most entertaining and informative KZfaq out there! Are those lead acid batteries? If so, are you providing ventilation for the gasses (hydrogen/oxygen?) that they can produce? Also, they will need distilled water for maintenance. Can't wait for each new video with you!

Another great vid! I love watching you guys as you show some really practical solutions, light heartedness and a bit of Shaggy to wrap things up! :) Can't wait to see you're engine pushing Uma along!

Another great video and great to see the engine move! Well done!

WOW......... LOVED that version of the song! Loved it!!

I’ve seen hand full of your videos randomly for the last few years. But now I’m watching from the start to finish. I’m very curious how some of these things will hold up with heavy use and rough seas.

Looking good! I remember being young and climbing in spaces like that, not any more.

Love your videos & how you are explaining the issues you are faced with & how you resolve them.

OMG I joined you guys through Cecilia's video on Svalbard ... I had no idea you guys did all this work. 100% Wow!!!!! I'm taking your binge watch recommendation 🙈😁

Another great film, thanks for sharing. Looking forward to seeing it all in action.

Can't wait to see the prop turn!

Loved your friend's performance!

I'm very excited re your engine! Can't wait to watch the testing results! Hurry up!! ;)

Love the work you guys are doing! Very inspirational.

I was yelling, turn the bloody things around, ha ha. Fun and games. Lose cables Dan.

congratulations to your brother and new wife. I love the creative bent you have with being more ecological responsible.

Your ability to work for extended periods in tiny holes amazes me. I'm having claustrophobia just watching you.

Bravo, I love your videos. thank you for sharing your adventures. I am looking to do the same and you guys are inspirational to the rest of us. Keep up the good work.

Great episode. I love electric stuff. Thanks!

Love the electric motor such a good idea

the next time you need to re-brush, you can place the sand paper flush on the commutator to get a close curve on the brushes. Also, some compressed air will help get the dust out and don't forget to megger everything afterwards!

Nice work you guy's, cool that your friend helps you out like that and Congratulations on your brother's wedding 👍😆 .

hi guys. rock solid job. love your vids, you hard work which will no doubt reap great rewards. Uma will be the supermodel of the seas. lol be good be kind be careful

Great video--and the dude can sing!

Very cool project! I was just over at Riverside last week looking at a boat and wish I had said hello. I am waiting with "bated breath" for the results of the electric motor project! I may need to invest in an electric motor company soon! Great work!

So glad you are able to go electric propulsion. makes the most sense to to use the sun when the wind is not blowing. No fuel; no noise. Up front expense but little down stream expense.

love it I'm paying attention love you tube. you guys are doing great.

Awesome video. I'm so excited to see Uma moving out under DC power. Can't wait for the next episode.

Only just catching up with you - really enjoying and loved the song with guitar!

That’s ducking impressive dudes

Nice job. I also am going to convert a an old gas/Desiel sailboat to electric. Looking for one in our area with a blown engine that I can get cheap/free. One thing to consider... Some manufacturers used props of different pitches to compensate for the motor being over/under powered. I.e. A 30 ft sailboat with an Atomic 4 30hp gas engine can't transfer that much energy to the water as it only takes about 10hp to get to hull speed. So the pitch of the prop is at a min. You may need to match you prop to the new motor so you get max efficiency out of the system.

Totally on pins and needles for the sea trials and so pleased to see them really doing the wiring super heavy duty. I don't remember what their solar capacity is but expect they'll wind up expanding that to any available space. I don't remember a wind gen but guessing they'll have at least one of those in the end. I think this electric propulsion can work but depending on how good they are at sailing in less then perfect conditions combined with the patience to sit tight and just chill if there is no wind. I don't remember seeing a vent fan for the battery bank....might not be a bad idea though small fans don't take a lot of power. It wouldn't have to run 24/7 but during charging could be a plan unless those are the lithium batteries which I don't think generate hydrogen or explosive gases.

Haaa! I unintentionally smiled when I saw you power that thing up! How cool is that. Good job guys!

Not sure if this has been mentioned, but you will need to "break in" that fresh copper commutator to build up a protective film and properly seat the reconditioned brushes.

Another great video... you will be over 1K on Patreon in no time with this quality. I was actually in suspense waiting to see if the motor would spin! It would be nice if you could somehow manage to charge using the prop while under sail. I know you mentioned that possibility a while back.

Interesting to watch your progress. A couple observations to offer. One is that the discoloration on the commutator of the armature is desirable and should never be "cleaned". You mentioned that it was uneven, so giving it a skin pass in a lathe to true it up is not unreasonable. Regarding the abrasive paper, you mentioned "sand paper" which is light in color and that is the right thing to use. In the video, the paper actually used looked dark which is likely to be something other than sand and is often conductive and therefore should never be used on a commutator. Lastly, the reason that control panels are built on steel backplanes is that they do not burn. Please pay very close attention to the current rating match between your contactors, wiring and fuses. Also, be careful to detect an overload situation such as a fouled prop. This will lug the motor and cause it to draw more current (could be a lot more). As I mentioned the last time, compound motors such as yours require field loss protection to avoid burning up the armature by applying power to it without a field present (the field provides the counter EMF that limits the armature current to a safe value). It would be wise to test that your armature voltage is not applied when you have no field current flowing. If this can occur, I advise that you add a provision such as a current relay in the field circuit to act as a permissive to the control for the armature voltage (example: remove the output from the speed control going to the armature controller). This is all DC Motor 101 so it should not be hard to find information on any of it. (I do industrial electrical maintenance and I design and build electrical control and automation systems).

Bonjour a vous, votre bateau sera parfait bon courage

Looks good, make sure your batteries are well ventilated. You would not believe the size of the explosion, I have seen it happen twice. I wish we would have seen the bearing you used. That first one was an oil bath bearing. It would have been short lived. I sure like the motor conversion.

Excellent! I am learning a ton from you both, and think you two are AWESOME!!!!! Great job on everything. I will be supporting you on Patreon for sure

This makes me excited! It's so quiet too! -Ryan

Really, really nice video you two! Thanks so much.. John H.

you two are nothing short of amazing

i've never had boat experience but had years of experience with motive power in the fork truck application. electric motors give maximum torque at 0 rpms and a clutch is not needed. however a speed increase would be beneficial in the gearing of same.. reduction of voltage will work for reverse. but speed needs a transmission. again no clutch is needed here. if your motor reaches acceptable speed in it's designed range go no further. if you want more the introduction of a gear solution is wanted. what you have already done is very impressive. you are patient, you think things out clearly. then you act. not a lot of people do this. you are absolutely the persons who should circumnavigate the world in a sailboat. the sea will test you but you've built a stout ship and know how to fix her. good on you and nothing but good for your future..........

I like the use of your feet to help this damn thing apart, I can guess you saved money do it this way and some great experience, but did you save enough in personal time if you had bought a predesigned electric motor system? You still need a good generator to run everything. I am an avid sailor and I work in Aero Space Electronics and I will tell what I see, it looks really darn good, great job!

There's also a lot more room where you have the motor placed than when it has a diesel in there. With the electric motor and the battery bank and the wiring setup you still have a lot of room to spare. Great job guys... ;-}

Loved that version of that song. rock on

Awesome! We had a good laugh about the King Kong motor :)

Wait. I started with a boat tour episode 22? and was so intrigued I've gone back to the beginning. I just realized this is not anything like working on a boat as I've come to understand it. There is no cursing!! :)

That engine! Quite the job.

That motor worked flawlessly, WOW!

Another great how to and everything works. Thank you

I'm an old school guy, but I have my fingers crossed for your motor. How cool will that be if it works like you think it will. Looking forward to watching your videos!

good imaginative work with the fresh styled opening of this film segment !! After all those buzzilion clips very similar... this total grabbed by attention .. would of anyway, but more so with this high quality imaginative approach.. another example of how u2 Rip'Genius !

that sounds BEAUTIFUL!!

Awesome guys, keep it up

Just catching up with your journey. Great stuff. Sorry though guys, had to stop mid video as you inspired me to get off my butt and get wrenching on my own projects. I'll be back though. 👏

Beautiful thank you!

Gotta give you guys some props. Nice work.

Lovely vid! You two are amazing! Inspiring!!!

Great job with the electric engine. I'm very optimistic that it will work as you expected. On KZfaq there is a channel (Eco Sailing Project) with a few French boys who succeeded in circumnavigating the world in their sailing yacht by means of an electric engine (and their sails of course). Very smart and environmentally friendly idea, I think. In case you don't speak French, their videos also have English subtitles. Their goal seems to be to inspire as many people as possible to switch from oil to electric engine on their boat. I think that's great. What do you actually think of salt water fuel cell-power on a sailing yacht?

Always interesting! Keep up the good work!

keep up the good work.

Very impressive DIY both of you. Bravo!

Insane guys insane work

Ride that bronco Brad ~ amazing cover of Angel ~ nice scooter too ~ I'm a total scooter mover.. two Vespas' , a 200cc and a 50cc , both modern day... and case your wondering about 'Tug' ...my boat like drivable Ford E350 custom boat like interior.. their fore my own BlackHole' is drivable ! Plus, Tug's been full time home for twelve years solid

Hi guys, I finally decided to watch all your videos from day one! Many questions and wonderings. I am hopefully getting a 36 feet boat (junk rigged schooner), as soon as Covid situation permits. It's an old boat of course. I am very interested in 2 aspects of your boat refit: - the interior (like getting rid of the center foldind table) - the electric motor !!! Question: how far were your electrics knowledge and skills before you started? Did you learn on the way? Thank you for all the videos and great ideas (and much more!) Patrick

Another great video, nice work guys.

You guys are so cool!

super-duper cool!

hi guys new subscriber..really enjoying your videos. .is there anything Dan can't do? He is MacGyver!

Good luck ....never give up

The electric propulsion will work fine-the problem will be battery capacity,range and how quickly you can recharge. Don't forget the propeller,I doubt if it is the most efficient for electric propulsion. Have a look at Lynch type motors.

Well done. Thanks for the video!

hahahah nice king kong shot there ;) PS that guy can sing, first i thought it was some real Jamaican lad orso

So you said temporary. What's the long term plan for control? Also, did I see correctly that the toggle switch is forward and backward? Very nice job. Can't wait to see the sea trial.

Great tip use of coffee filters to clean with

Great video. I will thing of doing the same with my own diesel engine om my boat. Super idea - Your friends guitar is a bit out of tune - but his playing is incredible :-)

Excellent video thank you..
