DIY UNDERWATER KAYAK THRUSTER - Part 2
HTML-код
- Опубликовано: 3 ноя 2024
- Part 2 of my electric propelled kayak home project and test. Results were just short of what I was hoping for but at 6km/h I'm still pretty stoked with the results.
If you keen to see how I built it leave a comment below and I'll put something together for you.
Thanks for watching.

Thinking of doing something similar. What motor, ESC and batteries are you using. Thanks.
Cool and useful -- thanks for these posts. Thinking about doing this for when I am mostly sailing the kayak and harder to paddle with gear. Personally speed won't be my goal but range -- 3 - 4 knots would be fine. Have you paddled your kayak at the speed you want? If not, then likely a limitation of the hull speed of the boat. Takes exponentially more power to climb that bow wave.
That is pretty cool, man!!
Cheers Des!
First thing I think is that maybe the motor need to be further apart so there not pulling turbulent air filled water threw them. Maybe a arm with 1 thruster on both sides. I also agree that 2 motors doesn't mean more speed just faster upto same speed as 1 and able to move more weight at the same time if 1 didn't have enough power to get u to top speed the 2nd will help I will be watching keep going
I get 6.2km/h on 20lb watersnake with hobie outback, drawing 18amp. Mate of mine mounted it on Ocean kayak and was getting about the same speed. Not sure how much power your motor is drawing but 6km on those tiny motor is not bad at all. Maybe you should try to mount one in each side of the kayak?
Cheers bud. I considered it but next time I'll be using 9kg ROV thrusters....6km/h is good....but I want more! 😝
@@MadSaffer Subscribed! Please let me know how you go with 9kg ROV. I don't use motor much these days as pedaling on mirage drive is as fast as motor and less things to carry. I'll be more than happy if it can do 8km/h
please give a link to the part that controls the power to the thruster i.e. speed. Is it 12V? I wouldn't know the correct specs for such a part. thanks
Amico ...anche io sto lavorando sul mio kayak con i propulsori...la potenza stai usando 12v oppure 24v ?
Hey, great project, have you any parts list from making this project too ? Thanks a lot
Hi Anthony. Sorry no. All parts were sourced from AliXpress.
The speed issue might have more to do with your kayak hull design more than the thrusters
I would strongly recommend that you create another motor mount on the opposite side with two more this should give you the thrust you're looking for and fight any of the wakes that happened
Hey there. Many thanks for the suggestion, I'll keep that in mind for my next test. Thanks for watching :-)
The motor runs at the same RPM the speed doesn't increase its just the torque that increases, so I think you should get a motor with more kv for a upgrade, but this video was rly good 👍👍👍
Thanks for the tip Neo, I'll look into that.
how long could you ride with those batteries?
It's a challenge to find an economical solution to creating a jet propulsion system that's cost effective. Including the drain on power issue. Putting it on the rudder is a great spot . Those parts are expensive. $1500 in parts is not a solution but still a great test. Until then the Minnesota kota is still the best way to achieve great thrust for a great price excluding the weight issue. Lithium batteries save weight.
Hi Kim. Agree, problem is, lithium batteries here in NZ are super expensive and I'm struggling to get them delivered from China. The motor was a long shot. I was hoping the 3 - 5kg thrust would be enough but after using them I wonder if the thrust rating was accurate. There's better motors available but for a steeper price tag. I considered trying those but compared to the price of a Watersnake trolling motor it didn't make any sense to try. May as well just mount a Watersnake then.
Really interested in the project would love some tutorial
Hi Mohamed. For sure. Once I find the optimal solution I'll record a tutorial. Thanks for watching :-).
This thing should have 100k views haha
Haha, it should be deleted bud... 😂
@@MadSaffer lol you don’t like it?
Was you using 2s or 3s lipo batterys?
Hey bud, I was using sealed lead acid batteries for the test.
Can you post a link to the motors you used?
Hi Josh, sure thing. www.aliexpress.com/item/33044732572.html?spm=a2g0s.9042311.0.0.27424c4dZcRhkW
Increase voltage it will spin faster.= more mph. 20 volt dewalt battery or 60 volt maybe overkill.
Heya Phil. That could work. My only concern though is battery weight. The cheaper batteries tend to weigh a lot but...I have been looking into lithium ion batteries which are relatively cheap if you bring them in straight from China....I'll make a note and look into that. Cheers bud!
@@MadSafferdewalt batteries are lithium batteries.
This motor not enough thrust and rpm.
Mmmmm....not convincing me at all - I prefer the Merc115hp on my Stabicraft, particularly getting back easygoing after a hard day’s fishing out wide in the Gulf 😎🚤🎣🐟🐟🐟
Haha, no argument there. Wonder how my yak would perform with an outboard... 😁
@UCcych2AokPN77kfa5NLr2tw if you had the 2 thrusters on opposite sides you could turn in place by reversing one motor while the other goes forward, which would be very handy
Good call, cheers mate.
Exactly my thoughts before seeing this video. 2 thrusters and 2 foot controls. Left and right of each. Then I could control the yak hands free while fishing.
