Tohatstsu 2 stroke= perfection and I’m saying that as an engineer/mechanic that modified everything! But otherwise This isolated cooling system would be great up here on the west coast mud
Man I would love this in the kelp. Put some sharp edges on those cooling fins and you're chopping salad. Too bad you can't move those fins to the bottom of the hull somewhere. Lower units love dolphins, turtles, sun fish, and whales.
Makes more sense on a very large outboard motor as the engine is so valuable so anything to improve the longevity and durability of that would be greatly appreciated I'm sure by boat owners. Like the shark fin on the cowling. Is that more than just a design motif?
Biggest problem I see with salt water is the salt in the air that is taken in the cylinder. I actually prefer the simplicity of the standard cooling and the flush cycle, keeps things simple. If invasive species is the concern, I would have simply made a filter that is simple to clean. Because life doesn't need to run through the pump to be hauled around.
I'd imagine as long as the water you're in isn't 70+ degrees you wouldn't have anything to worry about. Regular motors don't cycle through the head constantly, they have thermostats to control the temperature since the water you run in is generally between 35-70 degrees in most places on average, which would prevent the motor from reaching operating temperature if it wasn't regulated.
Looks like something I would have designed. I had the title “chief engineer”, my guys would say, “don’t let him (me) touch anything (math models, prototypes, test samples, test set ups) “. I did a hell of a job of finding virtual geniuses in the field of very analytical engineering my group did. They were are at least 50% to 100% smarter than me but I still loved to fiddle with the dials once in a while.
@@firstlightflicks yeah if you only run in it a few times a year, no bid deal. But if the boat is in the water every other day or stays in the water for days or longer at a time, then it would be beneficial. It has it's uses, just not for every application
@@jonathantheunacceptable4259 my boat stays docked in saltwater 24-7 and I’ve had zero problems with any corrosion or etc like what was explained prior, it takes just a couple minutes to flush with fresh water all this is is a gimmicky solution to a problem no one had
YALL GOTTA START MARKETING IN MISSISSIPPI NEAR THE FLY WAYS AND DUCK HUNTING AREAS!!! they are banningnmud motors like crazy up here. So these would be a great fit to replace them!!!
I'm old school and have no experience with Tohatsus. They could be amazing or they could be the Kia of boat motors, I have no clue. My question is do you guys have plans to create stand alone kits that can be installed on other brands of outboards? And being a dealer would the factory allow you the freedom to do this type of innovating or would you be violating some type of non compete commitment?
Tohatsu is very good, right up there with Yamaha in terms of build quality. One thing you need to seriously consider for every brand is access to parts and service.
The Tohatsu outboards are great, some of the most reliable on the market. In the Asian market, they are considered the best outboard you can get. They are also all designed for use in salt water, so this system is simply useless for them. You are more likely to have the lower unit stick to the mid section from corrosion than to have corrosion destroy the engine. If you need to operate in shallow or muddy conditions, then a ProDrive would work better than a traditional outboard engine with closed loop cooling. This design is simply useless and will get are just going to try to make money from those who don’t know any better.
It cannot be completely closed up and resistant to water getting into the machine as it still need air intake and exhaust which allows water into the internal workings of the engine. Just saying. It is still nice to prevent any Other openings in the machine such as outside water into the cooling loop. Good ideas but somewhat disingenuous presentation by the ads.
Why not just build a water cooling system with quality parts and materials. Don't need to reinvent the wheel for something that's been proven to work. Inboard use is fine, outboard not so much.
Did you say Tohatsu and Freedom motor in the same sentence? I have a freedom motor too, stroked 460 bb Ford in my 76 Sleekcraft Kauai. ALL AMERICAN. Now i remember Evinrude, Johnson, Mercury, Mariner having much more "freedom" heritage than Tohatsu. Not knocking their motor or your innovation, just not anywhere close to a freedom motor. Like calling a Nissan Skyline a freedom car because it has a set of Hoosiers on it.🤨 I dont think so Tim. Am very intrested to see where this goes, would be hard to compete against other cheaper solutions I'd think, especially when you tell the customer it takes some "special" $100 a gallon coolant which seems to be the trend now days with anything. Id be intrested to know your selling strategy against these other tried and true simplistic methods.
Mud motors are superior to that setup all day long because they are air cooled.Never had a problem with outboards and salt water,just flush them on the hose afterwards. This looks like a government operation.🧙♂️
Good Lord guys. I just finished a head gasket replacement in a 1978 70hp Johnson that has lived an abused life as a commercial halibut skiff motor in salt water. They used good alloys and engineering. There was almost no corrosion in the aluminum. The bolts were not spalled in like on newer motors. Getting in and done was a breeze. Don't spend hundreds of dollars per motor to overengineer your cooling system. Spend a few dollars per motor and use better stainless and better aluminum. The alloys you guys are using today is pure crap. It is what they used to use as sacrificial anodes in those old Johnsons. I don't understand why you bubbleheaded engineers don't listen to us mechanics other than the obvious: an overinflated opinion of your classroom education combined with abject stupidity that education cannot fix.
I love the ideal. It's pretty cool definitely with the heat exchangers.
Wow man, more power to you.
Interesting stuff, Crystal River is definitely as shallow as it gets, especially in the winter!

I'll take my 15 dollar ear muffs and 5 minutes to flush any day.
How does it handle cooling the exhaust output the way a normal outboard does the prevent overheating the enclosure of the engine?
Very interesting 👌.

God job,lots of luck.
That would be badass for back in the marsh…
Nowhere near as good as a ProDrive. And it’s way more expensive than a ProDrive.
We run both gator tails and outboards in the marsh - this motor would do great!

nice tohatsu
Interesting concept, I wonder how long you can run this without over heating?

@@jonathantheunacceptable4259..... This was developed in Florida and is being displayed in Gulf waters. In summer our water exceeds 80 degrees.
@@Mike-gw9yt gross, the 80 degree part lol would barely cool you off on a hot day

all it takes is a stump or something to rip one of those fins off and lose all your coolant just to be stranded.
It's for salt water so you don't have to flush the motor all the time, not many stumps to hit in the ocean lol
Not many John boats in the ocean either 🤣😂@@jonathantheunacceptable4259
@@jonathantheunacceptable4259 flushing the motor takes like 2-3minutes tops? I guess it would benefit if your storing the boat in the saltwater

At one time, and they might still. Tohatsu made all of the 40hp, and smaller for Mercury, and a few other brands. All they changed was the decals.

It's for running in shallow muddy tidal waters. They aren't reinventing the wheel, they're just putting some mud boggers on them.

It takes regular old ‘whatever you pay for normal coolant’ 50/50 coolant
It's a myth. Been hearing about these for 10 years
Must be banking on enough stupid people that would buy a stupider idea. How does the aluminum exhaust tube get cooled?
As long as the antifreeze don't leak at some point into and polute the water ecosystem it would be something I might buy
That comment just makes me cringe that you have the ability to vote, think before you comment
Valid point
Everything breaks down and leaks at some point 🤦♂️
