- First, let me give a shoutout to Tahoe YakFisher for sharing his PWM speed controller. I used the links he provided to order my component, which I also show at the end of this video. I built my controller for a WaterSnake 24 lb trolling motor for my 2020 Hobie Outback. I'm a big guy at 6'-2", 240 lbs and this little motor gets me around at 3 to 3.5 MPH. A PWM allows you to conserve your battery power, unlike the three or five speeds you trolling motor may provide. If you found this helpful, please Like and Subscribe.
Nice neat build! Thanks for sharing with us!
*This makes my old motor look like a toy **enjoyable.fishing** recommend it's well built. I haven't had it on the water yet, but I'm very sure it will perform just fine.*
This is the nicest set I’ve seen so far, so well made looks like it’s from a factory …👍🏻
Thank you!
Great workman ship! Finally a super clean build and install ! Thank you for the great video!
Thank you! Was a fun build.
That’s the motor I bought from you! Thanks again!!!
Hey friend, you are most welcome! Hope all is well with you and your motor. It's a great inexpensive set up especially with less expensive lithium ion batteries on the market these days. My replacement Newport Vessels NK-180K motor has worked out well. Tight lines!
I have the same trolling motor, i managed to fit my pwm in the head of my watersnake T24.
Pretty nice setup. Thanks for the mention.
Nice setup. I appreciate your time and effort to make the video. I'm thinking of a very similar setup on a FoldCat 375 (that I can transport easier and likely more stable than a kayak). I found a 40 amp hour (500 watt hour) battery for about 1/2 the cost of the Dakota. I am also contemplating the Sea Eagle bimini top to hold a 100 watt flexible solar panel to provide some shade while maintaining a charge on the battery. I could possibly use a smaller battery with less weight and less cost since most of my boating/fishing will be out in the blazing sun anyway. The down side is learning to cast from under the bimini top.
Thanks! Happy to hear you have a set up plan. Good luck.
Brother, that setup is KILLER! plus your yak is on a swing.. what!!!??? Lol where do you fish out of? You mean "54ah" at 2:34?? Awesome setup, awesome video.
Those 60 amp PWMs will run very hot when using them with a 40 LB. thrust trolling motor. I burned mine up because it could take running wide open for more than a couple minutes. I could smell the plastic burning and the variable speed control switch quit working now. I switching to the 100 amp PWM with the fan built in so hoping that will work for me.
Very nicely done but,,,,,I think a solar panel would be a good idea like a 200 Watt's square panel to charge the battery I making one for my canoe with a 24lb watersnake trolling motor I've got a 75Amp deep cycle battery it should go very nicely 😀 👍
Awesome . Still happy with the setup or have you made changes ?
How did you add the large heat sink onto the pwm controller? Could you show us the inside the box? Great job and thanks for sharing!
Hi how much time do you get out of your 54Amp lithium battery
Oops . . . 54 ah battery! Must have been stage fright! LOL.
very professional-looking setup, thanks for sharing. Do you bring your pedals out with you as a backup?
Thanks Peter, appreciate your comment! Yes, always secured the pedals at the back of the Hobie,.
Do you have any videos on how to wire the speed controller?
No, however, it is pretty much straight forward - power (battery) and motor (troller) with plus and minus connections. Thanks for watching.
Great vid dogg thanks for the info
Thank you and you are most welcome.
Nice idea using the heatsink, however the plastic box actually serves as a thermal insulator. It 'might' draw some heat away/out of the box but I doubt it's enough to be truly effective. Normally heatsinks (made from aluminum or similar) attach directly to the metal that's generating the heat. The CPU of a computer for example (which generates about 70-100 watts), the heat sink is bonded to the CPU with thermal paste to 'soak' and dissipate the heat away from the CPU. The plastic is a poor thermal conductor, that is - it insulates and keeps the heat inside the box. Again though, I suppose if/when the box does get warm it could dissipate some heat out of the box. I am using a PWM to control the speed of my Minn Kota 36 lb. motor (with the head removed), which is sealed in a food container. No vents and everything sealed water tight. The box doesn't even get slightly warm. I doubt you'll have any over heating issues with your 24 lb. motor. It doesn't draw as much current (or generate as much heat) as my 36 lb. motor. Also - nice idea of a voltmeter for the battery. That removes the guess work of guessing the capacity of your battery.
I totally agree with TC - the large heat sink on top should be directly connected to the transistor driver heat sinks for it to properly dissipate heat if the transistors get hot or install a small cooling fan facing the transistors.
Hi TC Bend did you use an in line fuse with your PWM
Great setup.. I am trying to do same, I am converting to a PWM. I have a question on how the heatsink was installed, is it connected to the small heatsink on the board or just basically part of the cover to absorb heat? Thanks again for the video, it helped a lot in my build.
Thank you and glad to learn it was helpful. It is a fun build. So, after cutting the heat sink to size, I cut the hole into the box lid a quarter inch smaller than the heat sink. I used a Dremel bit to grind away heat sink fins at the corners and drilled small holes for screws to attach the heat sink to the lid. Use silicon glue to seal it off. The heat sink just sits above the sinks on the controller board. Good luck and I hope this answer helps.
@@RickBrauer thank you for the reply... I may try to install the heatsink as well, just need to test and see if the temp gets too hot.
@@daverns111 Try to connect the large heatsink with the small transistor heat sinks for proper heat dissipation or install a cooling fan facing the controller board.
Nice clean set up. did you mention your motor size? And is the 54ah sufficient? do you have full day type use...?? Thanks
Hi Mike, thanks for the comment and question. The motor is a 24 lb. thrust Watersnake and does a good job of getting me from place to place over 5 to 6 hours on the water. Five to 6 hours is all I am good for, but the battery always has plenty of power remaining to go longer if needed.
I really liked your video at Lake Isabella. I am on the cusp of buying a new Hobie for Crappie fishing, and some Bass fishing. Mostly Crappie. I am 80% sure I want the Outback, as I was messaging a guy on a forum here in Texas about the Outback vs. PA14. I’m getting older and am only 5’6”, 150lbs. The other guy went from a PA14 to Outback due to the bulkiness of the PA14. Do you miss the PA14? Is there anything you miss about it, or does the Outback get the job done just as well? Thanks for your help.
Thanks John, glad to hear you enjoyed the video. To answer your question, no I do not miss the PA14 and very pleased with the Outback. At 71 years young and a big guy in comparison to you, I find the Outback fills all of my fishing needs. The PA14 provided lots of extra room around your legs, but I have managed quite well in the Outback. The PA unlike the Outback provided 6 rod holders (3 on each side), which was pretty cool. However, now I place up to six rods into vertical rod holders attached to the crate behind the seat. Bottom line, the Outback is perfect for me and I have not regrets selling the PA. Good luck.
I've always wonder if you could explain what percentage of battery you save if you running the trolling motor at 50% power, what are the amps drawn with and without a pwm Both running at 50%? i know at 100% power they both draw the same amount of power but the pwm its supposed to save battery so at 50% power how much power or amps are you saving, hopefully you understand what im trying to say .
Rodrigo - Thank you for your question. However, I am not sure I can adequately answer it. While a number of low end trolling motors use a 1-2-3 or 1-2-3-4-5 step speed controller, I simply wanted a true variable controller to allow 0 - 100% speed control for most water/wind conditions fishing banks. Again, thank you for taking a look at my video. PS - A couple months ago I upgraded a to a new motor, the Newport Vessels NK-180 24V, 60lb thrust trolling motor. A fellow yaker bought the Watersnake setup for his Hobie Pro Angler 14. I hope you will subscribe and hit the bell as I plan to upload a new video on the NK-180 soon. Tight lines.
How do do you keep the water out of the PWM controller with the heatsink on top?
Good question, thanks for asking. The heat sink is slightly larger than the hole cut into the box lid and used silicon glue around the hole opening on the inside of the lid. Hope this helps.
@@RickBrauer does the water get inside the top of the slots when it rains? I just didn't know if it's a one directional airflow from the inside out or of air comes in from the top as well,.and in turn let water in?
Great great video i am thinking of doing the same! One question how ling does the 54amhr battery last you with the watersnake trolling motor on a regular day of fishing?
Hey Mario, thank you for nice comment. I'm hopeful the information will be helpful to you. To answer your question, I fished about 6 hours last week and had plenty of power left. There was some wind but nothing too bad, but I work at conserving the batteries energy. A good practice until you feel comfortable with the set up. Like a bass boat, I keep my speed down for casting along the banks. Once I've reached the furthest point of the lake and wish to turn around, I will set the speed at 100%, reaching 3.8 mph into a good breeze. I have reached 4 mph at times. Overall, I am very happy with the set up.
You forgot to add the links.
Thanks for watching, I hope you found the information useful. As my narrative above says, I used links provided by another UA-camr for components, while I show the Amazon pages the links will take you. Good luck.
no links
Correct, but everything used in the project is shown at the end. . . .
