Find a trashed boat motor and just keep the housing and stick a pred on that, it hauls @$$ for a 6.5 direct drive, plus you can shift the trans from neutral to reverse to foward
👍
Harbor freight is only a few miles from me...I love their stuff! At least I can afford it!
Now you're talking! You are the farm version of Cars and Cameras 😂
LOL, thanks
Cool project 👍 Thanks for posting!
Thanks Mike, I actually just finished watching part 3 of the mini Pinz. 👍
Wonder what they would sound like if the exhaust was ran underneath the water like most boat motors are
I would say you need a smaller sprocket on the bottom turn that prop faster it is hardly even loading the engine now as it is. You would get alot more speed
I think it is loading the engine more than the video sound shows, but your right, I really want to experiment with different ratios and props
@@ChrisfromKeyfarm ya you probably right I can't judge it properly through video sound. Thanks for posting it was awesome!
Chris, the sound of your friends giggling made my day.
I'm blessed to have some really great people around me!!!
That is an absolute fantastic experiment. I enjoy all of your Predator experiments
Thanks, they are fun to build.
Use less steel and a lot more prop 2 blade twice the size I reckon
I want to do something similar but it's such a drought here in California I caught a catfish the other day that had a tick on it 😂
😂
Probably a 10 tooth sprocket. Could use lighter #420 chain for less parasitic drag?
I've thought about picking up an outboard from an antique shop and putting a motor on top of it? Could disable the water cooling I guess, cheap mud motor?
I have seen that done, they work pretty well.
I’ve been wanting to do one of these super cool
Do it, you to busy ripping around those mini bikes?😅
You should of used a used broke 20hp lower gear box jut couple the drive shaft to the motor you would have f n r gears as well just make sure no water gets is
Using an existing lower unit wouldn't be built from scratch, I've seen that done, I wanted to do something I haven't seen done.
A lot of noise and inefficiency to get less performance than a trolling motor cool though
Wow what a Debbie Downer ,supposed to be interesting not efficient.
Looks like it screams to not go very fast but very bad ass because he built it
No reverse also so that kind of sucks
I'm drunk and found myself in the correct youtube recommend
I'm not sure how to take that but thanks for watching.
great video, as always, and you will not have to worry about getting a speeding ticket Hehe keep up the weird projects.. love them.
No wake zone, no problem, hahaha thanks for watching, they are kinda wierd 😁
I built a "sorta" longtail mud motor using a 6.5 and your just about set to turn that into a short tail mud motor. Your current setup seems to block a lot of the water flow to your prop, maybe make the prop shaft a few inches longer and let some water get to the center of the prop, if you dont convert it to a short tail. My 6.5 using a 7 inch prop pushes my 1636 Jon boat up around 18 mph with my gear and carpeted floor in her. Nice job, about to start a short tail project myself
How long is your boat. I have a 12ft and am wondering about how fast i can get it to go.
I think it's 12 ft
Thanks for watching
Nice 👍 ! If you want more speed mount a cavitation plate above the prop and better handling along with protecting the prop make a skag and some sort of trim and tilt ! It’s very similar to a surface drive motor ! Your just going to town on those 6.5hp harbor freight motors ! Lol
Thanks for watching and commenting, I appreciate it , and I'll do some research to make it a little faster
@@ChrisfromKeyfarm I’m sure you will ! What next an airplane with a 6 1/2hp motor ? Lol. Maybe a hovercraft or a chainsaw, I’m sure you’ll come up with something cool 😎!
My Dad was talking about an airplane yesterday while testing the boat, hahaha.
Awesome!
@Maddog worker just means we have good taste ! Hahaha
Awesome Chris, great project and would love to see it in person. Keep on brainstorming!
Make it belt driven maybe way bigger prop still really cool can’t wait to see what you do and build one myself
If it were belt driven would the belt need to be in a waterproof housing, could the belt just be exposed (run in) the water?
Awesome idea. Gives me some food for thought.
Cool
Love it, good to see you having fun. Thanks for the educational entertainment means a lot to folks that can't get out and play anymore.
Central California Watching
Thanks, I appreciate the encouragement from central California 👍
Get yourself a bigger prop maybe. Good video I think I’ll stick to the Long Tails for now
Thanks for watching, when I revisit this project it'll have a larger prop.
Love your channel ,try running you exhaust down into the water,it will make it a lot quieter ,kinda like the old gamefisher boat motors,awesome job
Bigger prop I'd bet that thing would rip!
You do really interesting stuff with those Predator 212 engines. That is pretty awesome, when you consider how expensive a six horsepower outboard engine cost, and that 6 hp Predator only runs around a hundred dollars. That whole design can probably be built for $250 to $300.
Exactly Jack, the last time I looked at new outboards, I bout fell out😳
Yeah for a brand new Mercury 6hp your looking right around 1000 dollars and now. I've noticed they've also switched from carburated to fuel injected from the 9.9hp outboards and up. I'm sure its just a matter of time before they do it all the way across the board and of course their excuse will be the EPA regs are getting too restrictive. So we really don't have a choice. Nevermind the fact that it jacks the price of the oitboard up another 1500 to 2 grand. Ohh thats O.K. people can afford it. Its all just a money racket. I mean how much pollution is a little 6horse aircooled low compression small engine going to produce anyway. Its just another government extorsion sceme.
It didn't sound like the engine was struggling. Did you use some kind of prop calculator? How about a bigger diameter and different pitch prop? Try one you think is way too big, and then split the difference with a third.
I think I'm going to experiment with different ratios and propellers
If you have any interest in doing this again attach it to a lower unit of an old boat motor. (See chud327) they will cut through the water better with less drag from the chain, and possibly have reverse
I have seen those but I wanted to build one that doesn't require you already having a lower unit.
This deserves a big ROLL TIDE!
Looks like great fun, but I'm tryin' to decide if Ole Evinrude is smilin' down, or turnin' in his grave?
Yea, I suppose that could go either way.🤔
Another great presentation
question: can you make it Remote Controlled like you did with the - Homemade Radio Control Predator 212 Boat Parts Video - ??
I think you may need a strong linear servo unless you separate the rudder like in the previous video
It's possible
Awesome job!
Thank you, glad you like it!
Fix a few welds and your good to go! If I made one of these I think I might try and change a few things, but overall I think you got a good design!
Thanks
Now you need to make lower end aluminum
Pretty cool. You need to put the prop closer to the boat bottom. And your gear ratio is backwards. But thats awesome idea.
I'm going to try a smaller sprocket on the bottom shaft, but even with the larger one it works the engine pretty hard.
It maybe helpful if you make your prop where you can steer it all the way around on your boat that will give you reverse.
Anything is possible
Think I would try a way bigger prop
I went with this one for a couple reason,#1 props that fit a 5/8 smooth shaft are not readily available and#2 most outboards of similar HP have about this size prop
The transit is too wide at the bottom not allowing it to grab any water. Sounds like it has the horsepower to run a larger prop.......
👍 I'll get back to this project one day and improve on it
Yeah, that's a good start!
My 12' sea king will smoke that thing with a 35lb trolling motor
This was the first test, wanna bet?😅
@@ChrisfromKeyfarm 500 dollhairs🤣
@@slowstang88 how soon can you be to Flint creek in Hartselle Al., I have a feeling your going to sponsor the next project!👍😂
@@ChrisfromKeyfarm Not too far from me, I'm 20min south of Chattanooga TN. Also not sure what 500 doll hairs would buy you🤣🤣🤣
LOL
ide like to know what you used/bought for the motor mount system
I built a transom mount, I tell a little bit about it in the first video.
ua-cam.com/video/Eg2x2B1SHag/v-deo.html
Bro you should use 2 x 90 degrees gear box or a round pipe instead of rectangular bar it will reduce water resistant and go faster
I'm afraid 2, 90 degree boxes would rob a lot of power
dude if you have 12 hours to go half a mile that jack legged thing might work.
You watched the video, so it did work!
38 or 60 tooth sprocket remove the governor put on billet wheel better cam rods and get the engine into stage 5 sheez
Im not really a fan of wound out predators, I mean they are fun for a while but not much longevity in my opinion. Thanks for watching
This is awsome! Predator swap the world!
These are fun little engines, and if I sink one, well it's not the end of the world .😜
Do away with the clutch and you’ll get more power from the 212
Probably so.
So what I'm thinking is you probably get a lot more speed if you do a one-to-one gear ratio because at wot that motors probably around 3500. I don't think you're spinnin the prop near fast enough. Just my two cents but really cool project I'm looking into doing something like that myself
You could be right, I have a larger prop and different size sprockets, I'll definitely be revisiting this project in the future.
@@ChrisfromKeyfarm I'll be excited to see them!
Any updates did you try any other gear ratios or any other size props
@brandonlaragirl I still have this down in the shop but I moved on to building vehicles I'll get back to it one day.
That prop is definitely backwards on the shaft
Lol if the prop were backwards it would go backwards
That's pretty cool
Thanks
Awesome job man. Do you plan to use an idle pulley or does the chain not slap around much?
So far the chain isn't slapping, I can pretty much shim the motor to get the right amount of tension, but I do have a #40 chain idle sprocket if I need it. Great question, thanks for watching.
@@ChrisfromKeyfarm you’re welcome. I look forward to the next video.
Id buy a 212 outboard kit. Super coul
This one requires a lot of improvement but at the end of the day it did work.
Excellent project
It's the cheapest outboard I know of, thanks for watching.
a briggs and stratton motor can do alot! :)
👍
I would think the shaft version would be much more efficient than the outboard...keep up the great work
Thanks for watching
How do you keep the lower unit cool
It's just a sprocket on bearings it really doesn't create much heat and inadvertently the tube is filling with water and that would cool it if it needed cooled.
Cool projeck, try extending your shaft about 6 inches, and flip that prop the other way
Extension of the shaft may do some good so it can grab more water, but why flip the prop?
@@ChrisfromKeyfarm it looks like he has the prop on backwards
I believe the prop is symmetrical, it will function the same no matter how it is installed.
Prop looks to be backwards if you look at how the blades are cupped.
@@danpichee7034 I said the same thing lol
Prop is backwards, look at the cup on the blades.
If the prop was backwards, it would go backwards, it doesn't.🤔
Turn it around and try it.
Very cool
Thanks, this was the first time out, planning some improvements now, thanks for watching
Your propeller is on bassackwards lol 😂
Then why is it going forward?
@@ChrisfromKeyfarm it doesn’t matter which way the prop is turned because it won’t change the direction of thrust, the prop is cupped a certain way that grabs the water and directs the thrust into a tight spiral giving you more thrust = more power..
Looks to me like the cupped face of the prop is facing the front of the boat leaving the under cupped side trying to do the work that the cupped side is made for.. Just something to help get you up on step🚤
212+bicycle= new motorcycle ?
How about a 212 in an old motorcycle?, I still have a Suzuki I've had since I was 14, needs a new power plant.
@@ChrisfromKeyfarm after the bicycle you can do that unless you don't have an old bike then yeah do it to it !
I've put on a few pounds, I probably need to keep pedaling my bicycle,😅
@@ChrisfromKeyfarm your not alone from Halloween till now I have added 10lbs , I have a sweet tooth
👍 right there with you!
I see it . its cool project if your into gadgetry . but for most its better to just buy a outboard. Can get great used ones for cheap . but agin its 😎 cool.
I like building things that are interesting, and to see if it can be done, of course something that I build out in my shop for a couple hundred dollars isn't going to function as well as something factory built, but it's fun and we are all learning from it.
That loud motors gonna scare the fish away
Fish fear me anyway without the motor
@@ChrisfromKeyfarm hahaha 😆 😂 🤣
I always wondered why they don't put good mufflers on small engines
I'm sure bttr mufflers would make a big difference
Thanks for watching
Nice
Needs some refining, but it works
Awesome
I would really like to get back to that project and make some improvements
👍👍
Thanks
Coolness
LOL, thanks
What length square tube did you use a for the chain guard
I'll go out and measure.
The" down tube "as I call it is 23 in long
Thank you I was thinking about doing something like this since boat motors are so expensive right now, so I decided to google it.
@@ChrisfromKeyfarm what was the purpose of the angle iron in front of the down tube
At the top? Support, and it is hinged to the base.
