We really like your electric outboard conversion videos. Helsinki looks very beautiful on the water. Not many people can do what you're doing. I am trying my first conversion myself now because of you. I got an old Chrysler outboard for free and took the engine out. I saved the spline to go over the existing shaft. Just need to get an electric motor. 100 hp minimum. We hope you do more videos for larger 100 or 200 hp conversion. Thank you for the videos and the inspiration. It is really cool what you are doing and fascinating to watch. New electric outboards are so expensive. Scott from Vancouver BC.
Nice project of electric motor outboard...10k to 100k Rpm...a quite engine that can not use gas and diesel engine... Very high speed electric motor outboard...
I really like watching your process. I am interested in knowing how this turns out! I run a small fishing boat out of Southwest Florida. Thanks for sharing this with us!
Sir, it definitely looks good. I didn’t watch the entire video, I stopped when you drilled your coupling. It may not seem to be off center much, but it is badly off center. With it welded on, its not going to spin true, at higher rpm. Aren’t you going to tare out bearings? It seems to me your going to tare it up. If you need a new coupling, perhaps use a mill and a surface grinder. And balance it out, I want to do the same to a 9.9 Merc. So I’m learning from you.
I've been looking at conversion videos and what I have seen is pretty useless, not enough detail ... I'm only 00:27 in and already you are giving more info than the three I have already watched. I'll watch both and SUb. Thanks !
Hi. I think the controller need an 0-5V potentiometer/throttle. I think you are using an 1-4V standard ebike/scooter throttle. So when you start it gets 1V and the controller thinks you give it like 20% throttle. Cool projects you are doing. Im in to a cuple of electric projects my selves and learning as I go :) Greetings from Norway :)
Hello +Jarle høgenes ! Greetings neighbor! Yes you were right. Thanks for the info! I already made a new handle that uses the pot that the controller shipped with. It's working good now.
Ooohhhhhmmmmm ;) Great project! I figure with magnets it's a hall effect sensor? They are more precise and long lasting than mechanical potentiometers. Poti's tend to jerk their reading when they get old. With a potentiometer you normally have 3 connections with a slider in between max resistance strop so electronics can figure out at what percentage you are. My guess is you have to configure the controller correctly to stop either at 0 or at full resistance. BTW you could probably 3D print a mold and cast the rubber connector with silicon or polyurethane.
Hopefully you can help me? I'm trying to find the right size motor to convert my outboard to. It's 45hp atm the boat weighs about 850lbs and I want it to go pretty reach around the 30mph mark. Can you help? Love the vid!
Hey your rubber cush drive looks good now, the only thing I have observed is that you drive dog coupling on your motor hasn't been cut off square.... giving it more mass on one side, this will cause vibration and shorten the life of the shaft bearing.....it's just an observation. !!!! Keep up the good work 👍🏻👍🏻
Hey Pauli, great job on this! I'm working on a similar project with a 5kW motor. I'm currently trying to rework the propulsion shaft to extend it so I can put a bigger propeller with higher torque. Have you ever done or seen anything similar? Do you think it would have too many problems? Greetings from Brazil
+Igor Sampaio Thanks! I haven't done that, but extending the shaft where the prop is connected might put too much stress to the shaft and make it unstable.. You could try to cut the cavitation plate off to make room for bigger prop. Bigger prop is bettter with electric motors cos you can't get the same rpm but you have the torque to use it.
gears Pauli. lol. electric motors has loads of usable torque and you are throwing it away by using direct drive 1:1. think about it. a with a tiny starting motor connected to a massive flywheel gear can crank over a huge v8 engine. don't be afraid to put some load on your motor and get the prop spinning a little faster.
+HillbillyMatt ExtremeDIY I think you're trying to say that I'm throwing the torque away by not using a 1:1 ratio. Gasoline outboards have usually close to 2:1 ratio which makes the prop spin slower than the motor. You're right. But I'm not gonna try to modify the gearbox. The controller on this doesn't allow that much torque (amps) so it might be just enough for this outboard..
It don't need to be very flexible for outboard applications. You can print it slightly smaller and dip it in rubber coating like the stuff you dip tool handles in. plastidip.com/ It's only to dampen out vibrations. The actual gas motor has no such coupling and works fine , directly splined. the coupling you have is only to allow for minor alignment issues
FROM china MINE DID THE SAME THING!! OPEN IT UP RELEASE THE SPRING RETURN AND THEN IT WILL GO OFF! OFF NOT CYCLE LIKE THE E BIKE IT IS MEANT FOR. YES YOUR MOTOR IS FOR E BIKES SCOOTERS ETC... JUST SAYING OLD ONE LEGGED JOSEPH T.
pauli. you could cast the rubber star. just put the original in clay or something. after it is dry take it out and cast it in silicone or some ather sort of rubbery stuff.
You’re very talented & you do really great work. Amazing how your work was enough to help launch & new movement that became electric motor boating.

+Captain House You're welcome Cap! I was sailing around there 2 years ago. Very nice place to sail!
Hello. Nice project. Could you please put the items in the description?
Thumbs up from me - Excellent project.... I'm looking forward to seeing this working..... Cheers to you :)
+john wheatley Thanks man!

My greeting from Egypt Sir Pauli.that is a great job
Wicked build so far
👍👍👍😜🏴🦕🦄😁🤞✌️
Dang those couplings are industrial Legos. You could have got them with proper hole diameters for the shaft with set screws already in them for cheap.

Your outboard probably needs about 5,000 RPM for maximum efficiency.
Are those couplings easy to get im looking at a qs180 8kw motor to go on 30hp outboard motor
Hopefully you can help me? I'm trying to find the right size motor to convert my outboard to. It's 45hp atm the boat weighs about 850lbs and I want it to go pretty reach around the 30mph mark. Can you help? Love the vid!
Would a 12v 150w 15000 rpm motor work?

Glenn Fryer I was quickly going through the comments just to see if anybody else caught that. I agree
Yeah saw that too haha. He could probably file it off and balance it by using the motor itself as a "lathe".
on all your outboard elec conv motors
is there any that will change your batteries under sails?
nice idea

am thinking of
electric outboard
that will charge under sail
Larger or neodymium magnet
you've got some great funding. are you sponsored?
+coolo No funding or sponsors. Just me using my money from the work I do. Which is not at the moment :/

you need like 90v up for power my man
3D print a coupling bush .
+Mazda rx7 I've done it already if I've had a flexible filament :) But what I've read they are kinda tricky to print.

15708 bertram drive hudson fl. Airbnb. Stay for week free and help me with my sailboat.
tempting but now I have to work and get my boat ready for the summer..
All that for nothing.
be careful with China batterys lots of fire with them worth spending money on a high price battery if you like you house not on fire that is
Your wasting your time with this electric BS
pauli. you could cast the rubber star. just put the original in clay or something. after it is dry take it out and cast it in silicone or some ather sort of rubbery stuff.
+dextersxxxxlab Good point! I'll look into that if this one fails.
