Wherever and whenever I see a new Paul Elkins upload, my face lights up and my brain gets a hit of feel good hormones. Fantastic material. I did buy the plans for one of your other designs, but I couldn't get the right Correx at my location and she came out weak and floppy! One day soon, I'll set to on a V2.0.
I enjoy watching your videos. You can watch them and see various little things you’ve done. The little plastic clip to hold your phone! Awesome! I never throw anything out either! Inspirational!
The problem is the pitch of these props is designed for about 3mph max speed. You need a higher pitch prop. I’ve seen guys use model airplane props on them to get better speed.
The speed is slower than I would have expected. I get 3mph using an old 12lb Shakespeare motor on an Intex 200 tiny inflatable. I wonder if the prop could be switched to one with a different pitch?
I have a twelve volt, 100ah lithium battery for my trolling motor and it's fantastic, so far. Much lighter, way more usuable capacity, much faster charging, a cool app that allows me to monitor everything from my phone and it requires very little looking after. Damnably expensive though, given I bought a generic, Chinese, no-name, no brand version.
You should take a look at a lithium power bank or cells and making your own power bank. Really fun and easy to do. You can buy cells off ebay that are used for cheap but still in good condition.
I have a bank of fairly spent cells that som electric bicycler gave me. Have any of you tried the dangerous zap method to rejuvenating a lithium battery, yet survived?
@@paulwelkinsdiy I kept a NiCad drill battery going for three extra years doing this. When I let it sit for too long and wouldn't charge I hit it with my 12 volt battery charger, I even got it wrong sometimes ( reverse polarity ) but you can tell quickly by the needles movement ( up or down on my old charger ) I just recently purchased a new battery for it, new/old stock for the 18 volt Black and Decker that's at least thirteen years old. One of the Good ones 👍
Very Cool Paul. but I'm guessing your 12V deep cycle is down around 11V when running, and I'm wondering how much more voltage your controller might be good for? Going to a 5S or 6S (16 to 20V) LIFEp04 (Lithium Iron) battery pack should hold in around 16V to 19V under load and might give you a 15% to 30% increase in thrust and get you up to 4 to 5mph. You could build a 12 amp hour LIFEp04 pack for about $50. and it would only weight about 4lbs.
I've been doing some research on trying to get more speed out of these types of motors and basically have found that even with many tweaks, we're limited because electric trolling motors are designed specifically for that - trolling at low speed. Better prop, batteries and more thrust don't really change things much at all - like maybe 1.5 mph if you do all three. I have a 55 lb thrust trolling motor and it isn't really any faster than my 14 lbs thrust motor on my 12 ft boat. To go faster, we need to step up to a Torqueedo or ePropulsion electric outboard. They produce speed and power similar to a 3-4 hp gas outboard. Unfortunately, that's about a $2,000 investment.
With this more quiet boat you can infiltrate those swanky parties easier. Of course you'll have to wear nicer clothes. You need a boat with a second seat though...
This is a cool effort. I just finished a little tug boat project with my grandson, which I hope to get up here on youtube very soon. We have a 30lb thrust trolling motor on it, and with the kids driving it, I have to work hard in the kayak to keep up with them. Your site title of "temporary obsessions" fits my builds too!
If you find yourself doing more of these types of projects, I really recommend the Anderson series of electrical connectors, like their powerpole products. They snap together but with a very positive lock and are designed for tough use; been quite happy with them on my ebike projects
Hi Paul. Hey if you end up in the water those rubber boots are going to sink you even with a life jacket. Ur Prop pitch is for trolling. Love the video.
Hey Paul just ran the numbers for your hull and you are making hull speed. To get over that you would need enough power to get over the bow wake and into planning mode. With that said I know those trolling motors use a flat pitched prop because they are after the thrust not speed. You could try adding more pitch to the blades. A heatgun and a blade forming block so you keep them the same. It would be interesting to see what the amp draw is of the motor to see if there is room to draw more power out of the motor or if you are at max draw now.
This is interesting to me too, i've got a 62lbs thrust "Bison" motor, I originally got it to push a boat I made up the Middle Severn, the original boat was a plywood flat bottomed 13' x 3 1/2' punt with some curve at the bow and stern to give it some hope of moving, it worked quite well and I used x 2 75ah @12v leisure batteries to drive the motor. Now I've got an old 1980s 14' x 2 1/2' double kayak that I have converted to use the same motor and go up the same river (this time with only one 75ah battery and a 5 metre long lead of 4 core 2.5mm sq cable to connect the motor controller to the motor (see my recent uploads) ) There seems to be little to no difference in performance despite the different hulls. Apparently the motor draws up to 63 amps according to the specs on the bison website. I dont know how I can measure the draw.
@@mikestinyshedofdreams you just need to put an amperage meter in one of your power leads... just make sure it will handle the load. To work out a hull's displacement hull speed is rather simple. You take the square root of the waterline length in feet and multiple it by 1.3 this will give you the hull speed in knots. But long slender hulls will do better than this and short wide hull will not do as well.
With such a small boat the motor is probably not drawing anywhere close to the current it's rated for. So try a slightly bigger propeller with higher pitch to get more speed.
Could you get batteries further forward in the boat to even out the weight distribution? Maybe if you got two smaller narrow lithium-ion batteries instead of one big one, and put them either side of your legs towards the front?
Paulv - Near idea. I've been thinking about getting a little electric troller for my rowboat, too. Just wondering...were you ever able to experiment with placing the battery in the front of the boat? I ask becaise I'm seeing that you're putting all the weight in the back and that may be causing the boat to sit "bow high". A little weight up front might balance the boat better and you might pick up a little more speed. ...just a thought. Sailboat idea sounding interesting.
Try a Torqeedo motor they have better pitch and various HP to choose from. I use a Torqeedo Cruise 2.0 which is a 5HP equivalent but they claim 6HP at the prop. You would fly with that.
Paul have you ever dabbled with diy inflatable boats? i've been tinkering with marine vinyl fabric with nylon covers/sleeves for abrasion and puncture resistance. with a lightweight aluminum frame of sufficient size you can support low-PSI pontoons (sponsons?). a simple hand or intek pump can fill and you can be on water in no time. also super light weight and portable/hike-able. i figured the lightweight nature and simplicity of something like this might catch your interest. i'll send you some photos of my current iteration. you are a big inspiration of mine! cheers
There is an electric motor that is lighter (battery lighter as well) called epropulsion Vaquita. It would likely get you the 4-5 mph. Same with a bixpy. That said, a sailboat is fun!
One more thing I wouldn't be wearing those rubber boots in that little boat if you swamp it those rubber boots might make swimming to shore challenging.
@@paulwelkinsdiy What about something like Venetian Blinds? When they're open the wind blows clean through but closed? Well, they could end up like an umbrella in a strong wind 😬 Best keep it simple probably to avoid getting a Good soaking 🐬
I think you are getting a lot of drag with that plumb stern and that amount of power. You could make a more streamlined stern that bolts on and have a mid engine arrangement.
@@paulwelkinsdiy OMG no!!! For The Win!! I am not a native English speaker but so far I thought this was common knowledge...sorry! One of my temporary obsessions is sailing. Would be beautiful if it matched yours hahaha Do you think it would need a keel?
@@DoNotPushHere Yes. FTW = For The Win I was thinkin' about how a little sail might be helpful, but I know nothing about boats. It's a great build and just a sweet little scooter for the water. Love it!
I'd like to build a small boat like this. The only problem I'd have is the greasy state of Maryland requires you to license any boat with a motor gas or electric. That means you need a title for boat. That would be to much running around. Damn greasy state of Maryland I cuss you
Ugh... I cringe when I see that lead acid battery. You can pump easily 24v into that motor without it frying. Grab a 6s or 7s 50ah lithium ion battery and watch that thing go just as fast as the original gas motor one did. And nowhere near the voltage sag either that you get with that ancient battery tech
It isn't really the size of the motor that is the problem, it is the pitch of the blades and the speed that it turns them, trolling motors are designed to go slow.
Infinitely more agreeable than that grating whine. I'm sure right there you'll gain the mental space to think of a faster alternative. Love it.
It's just nice to see you back in your boats again Sir.

@@paulwelkinsdiy oh brilliant. Thanks, Paul. You're one of the most inspiring creators on RUclips, in my opinion.
Very nice work I really like your builds very inspiring
Love to see you going electric! This video is really inspiring
I guess you can up the voltage on your battery, and you should get more speed
As we get older quieter gets more important.
Yes , peace is good, we definitely drop our nuts more also.
Perfect speed, perfect noise level! 👍

Lithium 24 volt. Lighter weight. Also you know what would be cool. A mini trailer that the boat that could be pulled by the 3 wheeler

very inspiring builds cant wait to build me a workshop. thanks for sharing - much love
I'd really love to learn how to build a boat like this! So cool.
No sail boat, steam boat. Now THAT is a challenge
Some of the bigger Wilesco static models might be powerful enough for a slow ride huh?
@@DoNotPushHere got some of those. They won't. But maybe he has to build one!
Or a sterling engine, quieter, safer and easier to build but not as powerful. Some look like steam engines too 👍
I would definitely want to see a coraplast sail boat.

Yessss-sailboat! Please do!
By the way nice job wearing a life jacket. It sets a good example.
Oh boy... I should bring you up one of my 52v lithium battery packs and see what it'll do with that :)
I got eight mph out of my 36 lbs thrust last week! The lower I dropped the prop the faster she went!
Thanks for sharing! Always enjoy your videos.
Hi Paul. Hey if you end up in the water those rubber boots are going to sink you even with a life jacket. Ur Prop pitch is for trolling. Love the video.
Wrong on the flooded boots, but I think you're right on the prop pitch being set for slow going.
"There's lots of grease..."
::makes a grossed out face::
...yup, that's about right...
Looking forward to the addition of a sail. I'd keep the motor attached though and also use the weight of the battery in the centre for ballast 👍
That's a good idea. I might postpone the sail addition until summer when the waters are a tolerable temperature in case I upset the boat.
@@paulwelkinsdiy A Good wetsuit under your cloths, we'd never know 😂

Electric definitely has heavier components and is much slower, but ya, a lot easier on everyones ears and nerves.
Sailboat?? Oop I used to work in UK sailmakers in city island before, hope it’s strong enough and I wish you the best of luck😊
👍👍👍👍👍💨
Gotta put some better connectors on those wires, man. Amazing boat!
I like the 2 stroke motor better on it. You can always get a better muffler that would be much quieter
Now you just need a mini trailer and you can pull it behind your mini car/bike
With such a small boat the motor is probably not drawing anywhere close to the current it's rated for. So try a slightly bigger propeller with higher pitch to get more speed.
You could get one of those magnetic pans under it to catch those rascally screws
Another neat video! Thanks Paul!
That trawling motor can probably give you more speed if you changed out the prop for something with a steeper pitch.
Could you get batteries further forward in the boat to even out the weight distribution? Maybe if you got two smaller narrow lithium-ion batteries instead of one big one, and put them either side of your legs towards the front?
That looks like fun.
Armchair Quarterback chiming in here: Can the motor controller handle higher input voltages?
The prop pitch in these motor are very low, they are meant for trolling around way heavier boats.

captain elkins
I' enjoy, seeing you, bye bye máster!
I may not be correct but I think trolling motors can also be run at 24 volts. Would that give you more speed?
You can certainly overvolt it but maybe not double. Should be fine at 18v though. Test with power tool battery
@@wodgesad Thanks Wodgesad. Did not know that. Plus my battery is kinda old.
Oops my bad.
Over volting for the win
@@BakedAndAwakePodcast Heat isn't an issue. Water cooled.
Super
I would make a displacement hull for that motor. Or a strong enough motor to make the hull plane.
Hear me out. TWO motors
It might be the prop pitch that is determining your speed. If you have a 3D printer you could make your own.
you ought to drop a turbo charged 4 cylinder engine like those carzy river boats in Vietnam.
Thinking about putting a trolling motor on my float tube. Speed, I'm not worried about.
Try a Torqeedo motor they have better pitch and various HP to choose from. I use a Torqeedo Cruise 2.0 which is a 5HP equivalent but they claim 6HP at the prop. You would fly with that.
