Seagull motors are immortal - I was given one that had spend 25 years in an old leaky shed and it started first time - it even started after I dropped it over the side (after a few too many beers). It spend the night in 10 feet of water until I dived down and retrieved it in the morning - emptied the seawater out, put some fuel in it and it started first time. It's a cruel world.
Seagulls fly out to sea to die lol
One thing to bare in mind with those seagulls, those props are designed for slow revs compared to most outboards, if you spin them up too fast, they will just cavitate. Displacement speed is best. Mate fitted a 3hp diesel to a Seagull leg, mega fuel efficient but noisy as feck.
That plastic case for electrical.. remember to put some UV coating on it or it will be brittle in a matter of few months. Might have been better to use old ammo box that you can get from army/navy supplies or maybe a freight type store that has new.
You should change that to a trigger because if you accidentally fall out of the boat no one's going to be there to turn down the dial and the boat will keep on going without you. At least if it's a trigger it'll stop once your fingers off the trigger
Kill cord would do this.
"Dead Man's Lanyard" would be a great idea, For all boats with an outboard motor, it should be an enforced law. Just have alook at all the YT clips of boats going around in circles with no skipper (I use the term loosley)
With this setup you can indefinitely live in a boat.
Until your software wants updating or a sensor fails, or a battery catches fire. 🤣
That converted sailboat should be a lot of fun. They make nice campers and take very little power to move through the water.
I know $500 on a trailer a bit of work but moves well, it also feels good in choppy waters like it won’t sink👍
And way cheap if the sails are ripped and neglected. Cheaper to convert than restoring it as a sailing boat (by a large measure). And better than the planing hull, fuel thirsty redneck boats. More room to camp in the converted sailing boats. The McGregor 26 is a convertible sailing boat. About the only one (and it has heaps of camping space inside). Decked out. 😅
I reckon old small sailing boats make great displacement cruisers! Cheap to buy and convert, if all the sails are ripped and has been neglected. Way less cost and labour than restoring it as a sailing boat (by a large measure). 😅
Wouldn't you want the sails just in case something were to happen to the motor!🤔
This was such a cool watch. Thank you for sharing!
plenty of power from the sun for a slow boat. Great fun! nice project. I built a solar powered kayak with outrigger, two person. works amazing!
Yes, I made rafts from Clorox bottles to tow my panels behind my kayak, with a Minn -Kota trolling motor mounted to a milk crate on the rear with two 50 Ah Lifepo4 batteries that stay topped off. Too good to be true, but it works.
loving the boat content lately.
cheers from America
Great job, thanks for sharing 👍
Formula for a displacement hull is the square root of your hull length (in feet) x 1.3. Assuming your boat is about 16 feet that makes your maximum speed 5knots.
Semi displacement (which it looks like yours is) is slightly higher so multiply by 1.6.
1point 333333333 recurring : but who's counting .
Nice work. It's inspiring to see more clean/emission-free creations.
Thanks I like the electric solar setup
Good work dk nice setup
Cool man.
Glad to see them being used!
Keep it up.
Now that I have seen the power I have started work on the next idea for one or them👍
you'll definitely get some better performance if you move the motor to the centerline of the boat. great project!
What an awesome video. So precise and on point in audio and visual. And I have no clue but it seems you are really creative in how you use your tools. Great watch!
So good seeing something cool done with the old seagull! I had plan’s of hotting mine up and potentially adding a brushless motor for a hybrid but It was reduced to a blob in a bushfire,the only thing I’ve got left is the prop which wasn’t on the motor at the time.
You can find those motors pretty cheap in New Zealand like $100 there are heaps of them here
@@DktheWelder lol that’s how much I paid for mine here! It’s not something I’d seek, another one will find me probably!
Nice work.building out of the box is very creative. Problem is knowning when your completed.😅 I cant stop upgrading my solar pontoon boat. Every year there's another biild. Sail on sailor.
Nice job
Wow! A lot of work went into your ultimate product, great job! I'd suggest to place a cloth bag around that plastic box as the sun's going to beat the shiznit out of the plastic and then you'll have to build another custom box for your controller. Keep up the innovation!
Very nice. Have a great summer.
Will do!
Solar enthusiast here! Yes you can charge the battery while powering the motor in order to do so you’d need to be generating more power than you’re using. That’ll depend on the KW on motor and what “throttle” your running it at that time. Also what wattage the panels are. You could definitely design and build a full fledged system for a cheap price. I’d be happy to help if you have any questions about that.
Oh man it loos nice with summer! -18C here now, can't wait to get my bout out on the water next summer. Cheers from Norway!
I could not handle -18c ! Mid winter here is my -2c hopefully the weather stays nice all summer
We used to call these for Strawlers, somewhere between a sailboat and a trawler, the motor looks very efficient, would like to see more numbers on different speeds.
Doooood, you're a mechanical wizard! Cool show!
What a freakin cool self-made water block! Nice work man :)
It is easy with a milling machine but could probably do it with an angle grinder 👍
That's super cool!!
Thanks Joel 👍
Two videos in a week
I just love it
I wish I could put more videos out. This one was about 8months in the making haha
absolutely works....charging while motoring.....just make sure you have a good BMS
Thanks that battery charger also over charges the battery to about 52 v and the esc cuts out at 50v so I have to pay attention to it
@@DktheWelder get a solar charge controller (victron or something cheaper) that allows you to change its set-points ....charge to 50v. if your battery is 12S (12 cells in series) then you don't want to charge above 51V.
All of the flywheels on the seagulls have abit of play in them! That's totally normal my 102 is the same a d it runs like a dream
What a great build. I loved seeing the process, it reminded me of my pedal powered catamaran project 25 years ago. So many unseen design challenges, and I'm sure some you didn't show, but a functional prototype is the result. I miss machine work, thanks for sharing the project.
Thanks ! This was more of a test of concept for me the motor and esc wasn’t very well suited but worked out ok
Sick bro
Liked the boat mad skills goodonya
Absolutely awesome video mate, I love what you’ve done with that boat. What a great escape vessel 👌 that electric motor looks like it’s got some grunt.
Keep up the good work.
Cheers 🍻
Aussie Boat Guy 😎
Thanks , it’s a pretty comfortable cruiser and I am impressed with the electric outboard 👍
Really cool project! It's inspiring me to make something for the river here in Portland, Oregon.
That would be cool cruising a river , as long as you get enough power from the solar 👍
I used copper tubing from a ice maker. Wrap my motor and controller. Pump cold river water through it.
Lovely
you need to cap the shaft with a bearing that can take the vertical loading (i forget what they're called exactly, that are slightly conical and can take a load on the shaft axis) and this way there is no pressure on the coupling apart form the rotation.
Fascinating...
I wonder if you could use a rag joint coupler commonly used between the steering wheel shaft and the steering box on an auto . I think it’s called a rag joint coupler because it a round hard rubber disk reinforced with cord . There are 4 holes in the disk , 2 bolts for the flange on the box and the same for the steering shaft . Hope this helps .
Nice ,But night sailing has been disabled in more ways than one!
Good on ya. :-) technically that screen IS flickering, it's just that your eyes aren't fast enough to see it. ;-) better to say it looks smooth in real life or something like that.
I would use a stiffer flexible shaft coupling for the drive, less chance of shearing it under instant torque.
Yes I need something like that. What are they called?
Love that Kiwi ingenuity, don't give it up! I don't fish that end of the harbour but maybe we will see you out there some day, kind regards!
thiss is so coool
Yes. Charge while use is not going to hurt the motor setup but not sure if the charger can cope.
Ok, will the charger start draw more power if it’s running?
@@DktheWelder
I don’t know.
In theory it’s safe but I won’t say that because I don’t know the details of the charger.
Awesome.
Thanks!
Lot of work to do what a cheap trolling motor can do
best channel on youtube mate
Haha thanks I think so too but I am biased!
I know they can be a pain to get reliable but I'm beginning to like electric motors, enjoyed watching your vids with them.
They are finicky definitely need a backup gas motor out there , but impressive power!
nice
My dream is a large cat cruiser 100% Electric. There are a few big brands doing it now and amazing go anywhere cruising at no cost and little maintenance. With solar efficiency near doubling and battery break throughs the future looks obviously electric.
It would be great but you still can’t beat a sail ! A big solar sail would be awesome if it existed
I sail currently and love it but can only do it 10÷20% of the time. Too much or too little or wrong direction. Solar would be like a power yacht just point and shoot. But a solar sail now that's a fresh idea. Nothings off the table in the future
@@lifeliver9000 I totally get what you mean setting up the sail can be a hassle and it has to be the right conditions
Neat!
now that is some quality dampening oxide on the trailers leaf springs.
Seagulls run forever mate.
Neat. Maybe try direct drive from the solar panels?
Man you are good with tools
Haha thanks, I always end up doing tricky projects so have to learn alot
Sweet as bro.
That’s the style of cooling I tried to suggest.
Yeah thanks , it needed it for this setup. The controller still got hot but I could still touch it . How hot do they get before melting?
@@DktheWelder rule of thumb, touch it while counting to three.
Did you use heat sink compound?
Or 3D print a rubber gasket to allow the water onto the speed controller back plate without leaking.
If you're still looking for a new multimeter, _don't_ get one of those cheap-ish HT208 clamp meters. While it looks kinda cool and has a bunch of useful features, it is very power hungry and will go through a set of batteries in a month just on standby/occasional use. But more than that, it uses two tiny LEDs for backlight and they will burn out very quickly, rendering the meter unusable. It is also extremely slow, taking several seconds to give a reading.
My personal choice at this point is a Klein CL1000. It's an older model, but had pretty much the same features with better build quality.
I really need to get on with my electric boat motor. got the panels, hull, battery and donor outboard, but procrastinating on the motor choice. very similar use case, a little moulded plastic catamaran that I want running off solar so I can just trawl all afternoon without running petrol. The ski boat uses more fuel trawling than cruising at 30 knots, and the dinghy isnt very relaxing with the janky old outboard coughing away. target species is only Australian herring, the little cousin of kahawai. whilst they will happily take bait, I find trawling catches bigger and meatier specimens, the fittest of the pack. and cruising along the beach on a summer afternoon does offer some lovely scenery ;-)
The motor choice is a bit of a hard one , the motor I used wasn’t very well suited and in runner would be better and a water cooled esc it can get expensive pretty quickly! If you want to go fast look at the qs138 motor would get you moving!
At last someone is using the efficiency of a seagull propeller. Who knew. Sorry for the sarcasm great shop work.
A second-hand Hobycat mast & sail will give you an even longer range.
What flavor motor did you use?
If you mount the motor in the center you'd get a better reaction on your power .
All you need now is a solar water distilation system, maybe a fishing net and your set!🤔
You can buy little floating solar stills . And a fishing net would be good
Whats the size motor you are using and what kind of motor?
Luv the tinkering attitude and bit of Mad Max meets Elon Musk 👌
Haha , I like that👍
That looks like a 'barge pusher' prop., or at least a later replica. You'll only ever go so fast with that but it should be the most energy efficient with that hull.
I threw out the diesel in my keeler and put on a new transom hung Yamaha 15. When I changed the prop over to a 'barge pusher', I halved the revs and fuel consumption with no sacrifice of speed. 13 to 15 kph should be the limit or thereabouts for that hull, but that's fast enough.
Yes someone told me it was a barge prop I have other props but thought this would work best. Why go for an outboard over using the diesel engine in your boat?
Because it was unreliable, noisy, heavy smelly, old Bukh and took up a lot of space. It also had a fixed blade prop that slowed the boat down.
The new Yamaha 15 was quiet, reliable and outside. Combined with the prop it was extremely economical and a lot cheaper than replacing the diesel.
It changed the boat dramatically for the better.
Great work mate. Keep it up.@@DktheWelder
Very nice project 👌 👍
Do you have any plans on posting the schematics and parts list of the conversion?
Not really this motor and controller setup isn’t really that suitable for this setup it works but a larger in runner motor would work a lot better 👍
Never throw away a seagull the propeller is very high efficiency at low speed. Basically it's the same as the axiom propeller. Seagull had it nailed years ago.
Maybe you could 3d print a mould and cast your own lovejoy insert out of a higher hardnes silicon or polyurethane? Food for thought, could be fun 😊👍 keep up the awesome work
I am making a solid coupling at the moment so hopefully that works 👍
Have you anything on the conversion of the sailboat What did you do with the keel?
It is just a swing keel it is still there, i didn’t convert anything really it is essentially just a trailer sailer with an electric outboard
More grunt than the old seagul. You sound like a kiwi, but are you sure you're not a Queenslander? We alway weld in bare feet too. Won't learn. This was a fun watch. 👍
Bloody amazing mate. I'm picking one day my commercial cray boat will be a e boat
Thanks , im not sure commercial boats will be able to go far enough on electric I guess as batteries improve but I think it’s a log way away
@@DktheWelder I guess it probably all depends on how much room you have for solar panels 😂😂
@@peterbaiter6422you pull the panels on floats behind the boat.
@@gsp49 no you don't. Water is something around 800 times more dense than air takes a lot more energy to push/pull something through water than it does air
@@peterbaiter6422 one Clorox jug zip tied on each corner of my 100 watt panels seems negligible, beats paddling.
Great job on that motor build man ! I have been working on a 3d printed outboard myself ! Recently I tested it on my kayak with great results. I have a video uploaded if you want to check it out.
I did very nice👍
what was the electric motor you used???
It's so funny how much effort and time you have put into everything, but then you use a cheap Tupperware for the controller, when you could have also 3d printed a custom housing for it as well?
I have hard 400w solar panels on my house i wanna use 2 of them for a sun cover on my boat.
Surely you'll want to water cool a motor with that level of power.
you can get one off jetski because they more powerful parts than china small one plus they can take beating at 22k rpm still be in place
Interesting project, have you ever considered a toroidal propeller,? expensive but very efficient.
Apparently they aren’t as good as a normal prop check out rc test flight he does some interesting comparisons
I've always wanted to see a solar sale on a sailboat. Solar panels sewed into the sall fabric I have flexible panels on a arched roof for my golf cart as a charger 300 w only producing me about 5 amps 48v not enough to drive my cart but enough to maintain batteries and charged if left over several sunny days
I've always wanted to see a golf car powered by a team of sled dogs.
@@gsp49 I can send you a clip of somebody I know with a stripped-down Volkswagen beetle as a dog sled trains his dogs in the summer down a dirt road with it
Put the motor directly in the propeller, create a shell for it.
Easier to buy a 12 volt trolling motor.
@@gsp49 every time I think in this kind of project, sail with solar panel and a kitesurf kite for more speed.
I need a diesel asap
The Silicone in home repair caulking contains Sulfuric Acid. Not a good mix for electronics.
Imagine if you could invent something that could like use the power of wind and you could attach it to your boat.
I have one of those
Maybe you could make it wind powerd as well. The hull shape looks lime it could suit windpower. Imagine a boat using wind and solar. :) New eco tech is taking us i to the future. ;)
Oh, what are the specs of that motor. What a bloody powerful little unit.
There is a description on the picture of it at the start of the video, I don’t have the sail for it but could put a big wind turbine on it
@@DktheWelder I'm just shit stirring. Keep doing what you do, it's fun to watch and sure gives the kids some adventures too.
Once you get all the bugs worked out of this boat, it'll be awesome for you and your family to use.
Yes and the electric motor is pretty quiet and easy to use, thanks bruce
OK, so hear me out ... bigger boat, small tesla drive motor
what motor are you using? I'd like to try n use it for a diy ebike
I keep forgetting what it is , powerful little thing I put a picture and description at start of video of you pause it
Great video. We need more Croc welding😅
I hadn’t discovered croc welding while filming this haha otherwise I would have 👍
Can you match the amp draw with that number of solar panels? So you can run purely off sunshine?
@@HandymanMark no , the solar panels were making about 200w and I’m guess I was drawing 5000w going top speed. On a calm day I guess you could move really slowly and only use 200w. But sitting in one place for awhile charges pretty quickly
I understand. You probably need double the solar panel wattage. About 10,000 watts of solar panels
@@HandymanMark i think a big windmill on top would make some power too👍
Why not install a removable omnidirectional windmill to generate power at night
pretty sure pla will work fine for a coupling...whats the worsts case scenario
You Should Have Used an Under-Water Mounted Motor,
1) Cooling Taken Care Of ✔
+ No Need for Cooling Pump Etc ✔
2) Alot Quieter ✔
1 seems good 4 would be even better... right?
I keep looking at hoby cat and thinking a solar sun roof with trolling motors.
Dreams are free
I think about that too but they sit pretty low in the water and if there is any wind or choppy water you get wet so that’s why I went with a monohull . A catamaran would be very efficient and fast though
@@DktheWelder
Yes.
I am a warm weather boater.
I tend to only use them to go swimming from.
I have build a hobie cat 16 with sun roof, se it on my page
Make a pair of sweeps using sailboard masts. You can stand and use your body to row in a forward direction. Works great for when the batteries are dead.
I pull my panels behind the boat on pontoon sleds made from bleach bottles
