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
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
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.
Nice ,But night sailing has been disabled in more ways than one!
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!
Great job Kee up the great work !
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👍
Why not install a removable omnidirectional windmill to generate power at night
Luv the tinkering attitude and bit of Mad Max meets Elon Musk 👌
Haha , I like that👍
Maybe a bigger prop if it can be done
What are you using to be able to use the same battery that you're charging? I've been playing with a similar setup I was under the impression I'm forced to switch between Banks. One charging while the other ones being ran.
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.
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.
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.
The trailer hubs are off a model A ford
O wow really! I didn’t know that
Awesome. What is the make and model of the boat?
Kestrel 18 ft . New Zealand made not sure how old early 80s I think
@@DktheWelder thanks!
is this a former sailing boat?
Used to be a Kestrel trailersailor
It beeps because you have either got too high a starting torque (use a centrifugal clutch) or it has lost a phase.
Oops.
Didn’t expect you to put a battery to big on it.
12s limit.
I know it says 50v but a nominal 50v battery fully charged is higher.
Meant to be 48v but being a novice I didn’t realise it would overcharge like that ! I feel like I have a better understanding of it all now
@@DktheWelder
No problem.
It’s a very very common mistake.
For an example. An 11.1v battery is actually 12.6 when charged and 9-9.9 when flat.
It catches everybody out.
Can I suggest you get your battery builder to remove one set of cells from series and if possible add them to parallel?
The battery will last noticeably longer per charge.
Or, with the motor spinning the prop too fast, you might think about swapping the top 1/3 series cells to parallel cells and gain about double the drive time.
@@brucebaxter6923 it’s I have thought about doing that. Would I be able to do it myself? Do I want 36v instead? Then get a different charger
Neat!
Look out for sharks! Remember, when your electric boat is sinking and the sharks are circling, youl have to choose between being eaten or electrocuted! Not a great set of options!
🤔😊👍
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.
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)
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.
dip it in a thick latex coating. then carefully cut the lid free
there are nowhere near enough vids on small electric trailer boats, so thanks for this.
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!🤔
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.
With this setup you can indefinitely live in a boat.
Until your software wants updating or a sensor fails, or a battery catches fire. 🤣
Or until you run out of food, or your blackwater tank is full
This was such a cool watch. Thank you for sharing!
That beeping from the ESC when you increase the throttle from the servo tester sounds like it's going into a programming mode. There's a series of beeps that correspond to different ESC settings. Usually you just drop the throttle back to nil and it should exit the programming mode and start to drive the motor with the next signal. Also, you should get a smart shunt for the battery to monitor power consumption, voltage sag isn't linear with lithium like it is with lead acid... once the voltage starts to sag its usually close to being fully discharged.
That’s to much for me,when I played around with the beeps it made it worse😂
Change the motor? NO - I think the prop is your main challenge - that is not exactly a modern design - looks like it was designed in the '30s!!!I am sure you could find another burned out motor with a better design in a local boatyard - they'd probably be happy to sell it to you for a little over scrap value! Using the more modern design gets you better hydrodynamics, better bearings and more serviceability. Or maybe you can get a 3D printed prop to go on the Seagull carcass!
Best of luck - I think it's cool boat!
The motor is an RC plane motor, not really the best for this and the lower leg is just what was lying around. Wish I had to design a nicer electric outboard.
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. 😅
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. It's inspiring to see more clean/emission-free creations.
Thanks I like the electric solar setup
Lot of work to do what a cheap trolling motor can do
you'll definitely get some better performance if you move the motor to the centerline of the boat. great project!
Oh NOOOO!
HES USING THOSE CRAPPY COMPUTER CONTROLLED SYNCHRONOUS AC MOTORS! 😬😝
Mate. Getchaself an old Holden commodore radiator fan motor.
Make a long tail setup.
Hell, even a 190buck 55lb trolling motor leg gives my fifty foot 10ton Wharram 3knots.
Or my 13ton 45ft Hartley concrete ketch 2 knots.
NO ELECTRONICS! Just 400W of Solar panels, a few junkyard car batteries, and a voltage meter.
That's ALL you wand or need.
NONE of that complicated bollocks that's designed to fail and cost you lots. Perhaps your life.
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.
Mate, I get 10 tons of fully rigged 50ft Wharram Oro Catamaran 12km from Te Puna to the mount on two medium sized car batteries and a 190 buck 55lb trolling thruster.
650W at max.
You have far too much time, money, and sponsors pushing junk on you.
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 👍
OK, so hear me out ... bigger boat, small tesla drive motor
maybe the coupling gave way when the line wrapped up in the prop. carry extras on board. It may have saved the motor.
use a rubber collar coupling. I will work WAY BETTER!!!!!!!!
The Silicone in home repair caulking contains Sulfuric Acid. Not a good mix for electronics.
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
Why not just used the gas motor . That a bit of wieght. Extra stuff. Gas is way more energy dense.
I have hard 400w solar panels on my house i wanna use 2 of them for a sun cover on my boat.
Thanks man, love a Kiwi way.
Thanks do what you can with what you got,that’s what I did
pretty sure pla will work fine for a coupling...whats the worsts case scenario
Merhaba bu motorun devir sayısı maksimum ne kadar
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👍
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?
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 .
I pull my panels behind the boat on pontoon sleds made from bleach bottles
Wonderful, among the few, someone decides to use the sun to power a boat. Why isn’t this a main consideration instead of just fossil fuels. Electric motors is a real entry now, solar/wind are really ubiquitous now, cabin cruisers offers real roof surface for panels/turbines, why aren’t hybrids offered for distance boating at slower but steady speeds. I guess it’s not boating if you can’t fly at 40nmh.
A hybrid could work because there is not enough energy to move at speed from solar and wind . Nuclear is the way to go haha
Surely you'll want to water cool a motor with that level of power.
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.
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?
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
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.
has to much power... noone ever sad before
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.
loving the boat content lately.
cheers from America
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.
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?
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.
what was the electric motor you used???
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
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
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
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. 👍
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 .
maybe you can, with at least two batteries, while one is charging you use the other.
Mine never discharge enough to switch, the panels I pull behind the boat keep them topped off.
now that is some quality dampening oxide on the trailers leaf springs.
I used copper tubing from a ice maker. Wrap my motor and controller. Pump cold river water through it.
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!
what is the electric motor?
At last someone is using the efficiency of a seagull propeller. Who knew. Sorry for the sarcasm great shop work.
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 👍
Great job, thanks for sharing 👍
A second-hand Hobycat mast & sail will give you an even longer range.
Seagulls run forever mate.
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.
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!
I wouldn't cal it D.I.Y
Neat. Maybe try direct drive from the solar panels?
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.
what's the name of the boat?
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
Sailing most expensive way to get somewhere for free
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
If you mount the motor in the center you'd get a better reaction on your power .
Whats the size motor you are using and what kind of motor?
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!
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
Great content! I enjoy to watch each step.
Thanks ! Hoping to take it out again this summer
I need a diesel asap
Great project!
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 👍
