Here in California it’s basically all e15 fuels.. even at the fuel docks mostly.. if i let my boat sit for a month I typically get about a gallon or 2 of water in my tank.. my water filters manage to grab most of it and the fuel treatment does the rest.. i have 3 large water separators in line on my boat with large plastic see through caps on the bottom of each filter. I believe they are diesel filters but they work. They each have little drain valves so i can hold a bottle under them and drain the water out easily

Great video. No surprise, they're all really good. The experiment with the fan blowing over the jars of fuel is fantastic. All sorts of science happening there. The reason there was more condensation on the fuel with the ethanol is because ethanol is more volatile. It "wants" to evaporate more than the gasoline does. In fact, the ethanol "pushes" on the air with a pressure of 1.2 psi whereas the gasoline pushes with only 0.3 psi (a.k.a. saturation pressure, for a 77 F day in Florida). When liquids evaporate, they tend to cool down. Pour some rubbing alcohol on your hand, it feels cold. Since the ethanol in the fuel has a higher vapor pressure, it evaporates faster, and cools more, resulting in more condensation. You could repeat the experiment with thermometers in each jar and see the cooling effect. Every little bit helps keeping my old Mercruiser 470 limping along. Thanks for keeping us all informed.

That's the idea behind it, but some parts are missing. gasoline is NOT a single standard molecule like ethanol. The composition of gasoline depends on where you live, the climate and temperature, and the refinery that produces it.

Startron!! The absolute best additive to use for fuel containing ethanol! Of course that’s just my opinion from using it!

I have run ethanol fuel in my boats for years and really never have issues, but I'm only running a 20 gallon system and like you said, tank size makes a big difference. I also run my boat practically year round. If I know I'm putting the boat away for a few months, I run my last tank or two as ethanol free. In my experience, the biggest problem is the fuel sitting, whether its a 20 gallon tank in a car or a 200 gallon tank in a boat. If you use your boat often and have a decent fuel water separator in your fuel system and actually perform regular maintenance, you'll likely never have a problem. If you're one of those people that's lucky to get out 4 or 5 times a year, you're best off sticking to ethanol free. Just my $0.02. I'm an auto/diesel tech and I'm currently working on a truck that's been sitting for a few years, ethanol gas has wreaked its havoc on the entire fuel system. every line leaks and i'm pretty sure the tank is about rusted through from the inside.

Dealing with water in the fuel in a 120 gallon tank. Just the prefect time for this video. Thanks a bunch..

A very smart, greyhaired engineer helped this issue on a friends boat by putting a lighter to a 'fuelsoaked' piece of rag. No fire, no flames but the smell of fuel was still in that just wet rag. Since that day i leave my fuel tanks dry and my fuel stored in canisters. And they lived happily ever after...

Thank you. This explains why I haven’t had any problem using ethanol fuels... (which is all I can get at the local pumps)- I usually only add/use 5-10gals at a time(lake boat).. and use stabil marine 360

Great explanation. It was a night in day difference in how my yamaha behaved after I pulled and dumped the tank and went to no ethanol and a spin on fuel filter. I haven't had to mess with my carbs since then when before it was almost an every year battle.

Thanks for the video, well done. Pulled the fuel sending unit, put a 1/4 in line to the lowest point in the tank and syphoned the water out. Put a 3 foot by 2 inch towel on the end of a rod and tried to mop up all that was left. Put in a fuel filter with a water separator and drain cup. Rock solid.

I've always known this, however, I've never seen it demonstrated this way. This was super awesome to see! Thanks for posting.

Great video, thank you 👍 Fuel evaporation rate is incredible, thank you for showing this test. I'm using 95 octane fuel for my Mercruiser 3.0 inboard engine, it burns cleaner and less carbon deposits.

When ethanol was first introduced here (Gloucester, Ma) I was about 10 miles offshore in my Sea Pro 21' W/A with an 81 gallon tank powered by a 2 stroke 200hp Suzuki. The engine died but was able to get it running barely. With a couple of starts & stops only managing about 4 knots I made it in. It tuned out the ethanol was loosening all the junk in the tank and clogging the fuel pickup. I replaced the pick up and all the fuel lines and filters and never had a problem again.

Another interesting and well documented vid. Thanks. Here in South Africa, we are supposed to have ethanol in our fuel, but it seems that the legislation requiring it somehow stalled. After a bit of research, I'm really not sure if we have any ethanol in our petrol now. Nevertheless, we also on occasions fill up with absolute crud at the fuel station. Add to that, crossing the border into Mozambique (many of us take our boats offshore there) for example, the fuel becomes quite interesting and often doesn't even smell like petrol. For these reasons, any boat I've owned that had a built in fuel tank, has had the tank stripped out and replaced with smaller portable fuel tanks. This way, the fuel quality can be monitored better and there's much less opportunity for water ingress. Add to this, a well maintained water trap/filter and you feel a lot safer out on the water. It's a hassle, but well worth it IMO.

THANK YOU! This was the most informative fuel education I ever received.

Diesel fuel is hydroscopic also so you may need to use an additive. The best thing is to use it up when it is "fresh". Good article!! Thanks.

I've been fortunate to have ethanol free gas available on the Texas and Louisiana coast where I fish. Also use Yamaha Ring Free and fuel stabilizer with every fill up. My tank has a 72 gallon capacity, but most trips I only put 45 gallons in and try to burn most of it up. I also run my engine monthly in the off season to keep the fluids moving. Never had fuel related problems. Knock on wood.

I fuel up about once a week using whoever is cheaper. Never had any motor issue at all in almost 30 years. My boat is out a couple times a week year round. Current motor is a 2001 25hp Yamaha.

I can only get 10% ethanol fuel at gas stations here in NJ. They do not sell ethanol free fuel anywhere around here. My only other choice would be to buy fuel on the water. Unfortunately, I’m not ready to give up a kidney to afford an on water fill up!

I drain the VST and injector rail any time the boat is going to sit for any period of time. This draining seems to prevent the injector clogging and fuel pump issues I was having before.

Of course your are right. As you know not everybody can boat comfortably year around. One long term storage option would be to empty the fuel tank & cap off the vent(s). I think somebody even makes desiccants designed for this purpose. Having a good filter/water separator is important. Avoiding the problem is the best strategy; buy clean fuel and consistent use you your boat burning through all the fuel supply regularly.

The yellow cake powder left after ethanol fuel evaporates is also a major reason why carbs jets and fuel filters get clogged up.

Last winter I attended a boat show seminar put on by an instructor at a local Marine Maintenance Technology program. His assertion was that the main issue with ethanol is that it's a solvent (being made of alcohol). He said that if you always run ethanol in your boat since new, you won't have any problems. However, if your boat is older and has never run ethanol before and then you introduce it, it can loosen up lots of sediment which then gets into the engine.

Ahhh...A lesson from the ethanoligist....great lesson. Fortunately, the marina only uses the good stuff.

That truly explains a lot. My father in law always had water in the fuel. Who knew 🤦‍♂️

6 months ago and Rec 90 was under $3,00 and now it’s $450… thanks Brandon

Even though I've been using ethonol free gas, I have been battling a water problem in my fuel, emptying the water from my water separator and even getting my tank pumped. Very humid here in Florida. Once I started using a fuel treatment additive, problem was solved. Now I know why and understand how the condensation gets into the tank. Thanks for the video.

For pre-mix two stroke add marvel as recommended but then add pre-mix oil to the next thinner/lighter recipe (if you require 40-1 , mix it 50-1, etc..)

I have a 2017 Suntracker 22ft with Mercury 150. When I bought the boat its has about 40 hours. The prior owner only used standard pump gas boat had about 10 gallons in it when I bought it. I ran that gas out and now I travel 75 miles one way to the only NON ETHONAL fuel station Ill fill up 7 5 gal cans 6 for the boat and 1 for my mower and my little Honda Monkey I also fill my car and it runs 100% better with way better mpg. My boat also seems to start and run better with less RPM. Im hooked on NE fuel for my boat

Ty.Ive been trying too tell a lot of people this and no one believes me lol. Here in Canada there is only premium fuel at boat pumps only for this reason but premium fuel is ridiculously expensive here lol.

Actually a Cars fuel system IS vented to the atmosphere. The difference is that there is a charcoal cannister that is inline of the vent to absorb the Hydrocarbons in the fuel vapors. This is why you never (if the vehicle is not broken) smell fuel when standing near a modern day vehicle. on a boat, well you already know and probably know better than me.

props for showing lake sakakawea

#510591 Ethanol is hydroscopic, meaning it attracts and absorbs water. Running that fan over the jars causes a pressure drop which increases evaporation. The evaporation reduces the temperature. The moisture was forming on the jar because the temperature of the jar dropped below the dewpoint and the moisture in the air condensed on the jar. It doesn't take much temperature drop when in high humidity areas to reach the dewpoint.

I’ve heard you can put metho in your tank to mix with the water for it to evaporate. Works in a car.

Most of us don’t really have a choice of Gasoline or Ethanolized fuel. E10 (10% ethanol) is the most common and is what most late model marine engine manufacturers say is the maximum. As to E15 (15% ethanol) it’s actually a federal violation to use it in your boat. What’s that tell ya? Ethanolized fuel absolutely swells many elastomers (rubber), polyesters (in fiberglass) low density polyethylene, but not high density polyethylene (portable fuel tanks) PTFE (Teflon) and a few others. Which brings me to fuel lines. Only the flexible MARINE fuel lines of the last four or five years has any good chance with ethanolized fuel. It should be printed on the side “USCG approved type A-1 low permeation and a date of manufacture”. (USCG require the flexible fuel lines replaced every 10 years). My favorite fuel line brand is Trident. Older fuel lines inner layer tend to crumble and literally make a solid plug at the first point of constriction as well as the hose falling apart. The new replacement hoses need more hose clamp pressure and also need retightening in 24 hours and at 6 months as the new material flows slowly under pressure. (Always use stainless and double hose clamp) Now the ugly. Besides ethanolized fuel absorbing moisture (hygroscopic ) it can do something really bad, it’s called “phasing” . This is when the fuel separates out to distinct different layers. Gasoline on top, ethanol, water and a thin layer of sulfuric acid at the bottom. This is what eats the crap out of the bottom of the the fuel tanks, float bowls, fuel pumps, coolers, vapor separators and more. Phasing usually needs several conditions for it to happen. A vented to atmosphere tank, below or close to freezing and enough time for moisture to have been absorbed into the fuel (+3 months). Once phasing has happened there is no additive on the planet that will reconstitute the mix. Replace the fuel or carefully drain the stuff below the gasoline out are your choices. If you do manage to get past the water and get it to run on the ethanol, it will run extremely lean because the engine isn’t jetted to run on it. You may find some guys fighting with a motor, finding and the only way to keep it running is the feather the choke. Then one Einstein says “let’s take it out and blow her out”. Bad idea-LEAN! Yeah blow her out alright, the last time. If you want to know if your fuel has water in it (ethanol absorption or rain) or even if it phased, there is a product called “Kolor Kut” and you want the (modified formula) for all types of gasoline. This is a paste that you coat thin layer on a stick(weighted rope?) and stick the tank. Hold it down for about 5 seconds and pull it out. You can tell by different colors on the stick if there’s water and/or ethanol below the gasoline. If you want to help keep your fuel fresh, use Startron additive but it is no miracle worker, additives have limitations. Bottom line, best to keep the fuel fresh. Consider rotating the fuel out to another vehicle if you can’t run it. Be aware it may cause other problems to completely empty your fuel system because some components may dry out, harden or crack.

Just bought a boat that has sat on a trailer for 3-4 years (never ran). Had no idea how much fuel was in it, but was told it was "empty". Put 10 gal of non-ethanol fuel in it, then drove it around the block to stir it up. Drained it. What did I get? 11 gallons of water and 15 gallons of fuel. And when I say "water", I mean . . . crystal clear H20. Like you got it from a faucet. Almost no smell to it, either.

We have taken our portable tank out and got inside with a microfiber cloth and cleaned all the water from the tank.

Just dealt with white powder through out my entire fuel system from ethenol what a nighmare. That fan experiment blew my mind ! The problem with using heet or some type of water remover additive it will separate in the fuel/water separator and vst tank since the main ingredient iso-propyl alcohol is heavier the gasoline. They are useless. Also have fun switching from rec90 to ethenol. The ethenol will clean your tank out and all the varnish will break down. I like your idea of switching back and forth.

Why don't they make 1. A fuel tank with a drain on the bottom so you could let the water out until you get to fuel? or 2 Don't they make water separators for fuels systems like a filter that can also catch water? 3. Could you fill a tank with half E and half non? That would cut it down to 5% and still save money at the pump? BTW love your channel you are very knowledgeable and always have great content TY

When he said to not have much fuel in the tank is better. I have a power sports business and have been in the same location since 1979 and we store about 250 boats every winter from about September to the following spring may ish along with winterize close to 1400 boat's a year and we have done research on water getting in the fuel tank during storage for over 15 years and is still something we pay attention to still to this day.. we have found boats with built in fuel tanks 20+gallons of fuel left half full for the winter 9 times out of 10 that boat will have water in the bottom of the tank in the spring. We have seen as much as 4 gallons of water accumulate over the winter... We have done this with the same boat the next year and had the customer fill the tank before he brought it in for winterize and storage.. the customers didn't really think it was going to make a difference.. but it did not have a drop of water that spring. And he didn't have to spend any money having us get the water out and running correctly.. but of course the next year he wanted to help us in a way but he was hoping to prove that's not what was happening.lol... so I was all for it so it was stored in the exact same place as it had been the last 2 years.. so spring show's up and time to get his boat out for the season.. I had the customer come over and actually help get it prepared for the water. So I asked him do you just want to start it up or if he wants to pump the bottom of the fuel tank? If there's water in the bottom and we start it the water is going to end up in the carburator and it will have to be taken apart and cleaned if that happens.. so he said let's pump the tank first like I wanted to do from the start... So anyways almost 2 gallons of water wass pumped out!!! So with all that said, I would like to add that this has been done with well over 50 boat and other vehicles of some sort for over 15 years on everything from boats,built in tanks and portable tanks, jet skis , snowmobiles, and many other things with a engine.. so now if a boat is stored at our shop and the tank isn't full we pump the tank before we start it up in the spring. And let's not forget that I make money by cleaning water out of the fuel system and cleaning the carburator's . So in the long run we lose money but we have very happy storage customers and are very loyal to are shop. Not just from this experiment but many other reasons.. it's not all about the money at are shop it's about doing the right thing every time you deal with someone!!!! Anyways this is just what we have found out over the years. And the new fuels I still like better than the fuel 10-12 years ago since It doesn't varnish up as bad.... and stink up the hole shop lol... Hopefully this information will help so other people and families save time and money by trying this especially if you have ever had water in your tank come spring time... Have a great day...

ethanol when mixed with water becomes acidic causing corrision to most metals

A few years ago, i went to the auto parts store to buy a couple of feet of fuel hose. They wanted to know if I would be using ethanol gas as the fuel hose is different. There was not a significant price difference so I bought the ethanol fuel line thinking it would hold up better when using ethanol fuel. What are your thoughts on that?

I am curious about the effect of plastic fuel tanks vs steel or aluminum tanks. It seems condensation is less likely to form on a plastic tank, so if there is less air flowing and and around it, you would have less moisture forming with temperature changes. I rarely have water in the tank with plastic tanks. Also, how difficult would it be to retofit older boat/s tanks to be a closed system, so there is much less exposure to outside air, and moisture?

And I thought someone siphoned gas out of my tank during the winter storage. Problem solved!! Thanks.

The difference lies in the boiling points. Ethanol evaporates at approx. 78 ° C, while the boiling point of motor gasoline is between 30 - 200 ° C, depending on the type. Car gasoline belongs to the middle class and has a boiling point of approx. 85 ° C. Water evaporates at approx. 100 ° C. That is why the ethanol evaporates first, then the gasoline, and what remains is water and residues. When ethanol evaporates, it cools. That is why water vapor condenses on the cool glass.

Always used regular gas back in the day with no real impact gas was cheap and burned thru it weekly. No I only use rec fuel still no impact don't burn too much but I feel like I'm going something good for my brand new tohotsu... South Florida has a lot of different views on this matter and in the end it's personal choice -

investigate phase seperation. ehtanol will not mix with gasoline so a catalyst is added so it will. over time this catalyst gets used up and converted. then the ethanol being higher specific gravity will drop out and fall to the bottom of the container. sometimes it is very clear there will be a water line on the bottom then you will see another line higher up. that is where the ethanol is lower and the gasoline is higher. ethanol also has a lower octane rating so when you get seperation or dropout you are also picking up lower octane fuel and burning it. if you cant use up the ethanol in two weeks dont use it. if you have portable tanks or cans for your mower etc keep them full as shown here . its better to have 5 one gallon cans full than one 5 gallon tank part full

Nice vid

I run e10 in my 40 gallon tank. Luckily I’ve never had a problem. I treat with stabil and burn 2 tanks a season.

In my case, Ethanol free is available. However, I have never run it. I get stuff local to the house and have been doing that for decades. Carbs, efi and direct injection all burned the ethanol fuels. I have never had less than 40 gallons on the boat and I store my current boat full of blended fuel for the winter. 218 gallons and never a sign of water. The key is to key is to keep the tank full and treated. The more air space in a tank, the more it breathes. And the example of off-gassing and moisture retention is valid. However, our boat systems are not fully open to airflow or the resulting moisture dropout from airflow across the surface. The vent is small, 5/8" diameter typically. So, all that breathing action has to happen at a distance away from the fuel tank. The information of the video is valid. But in running ethanol from the beginning, I have never had a fuel related issue. And that is everything from my commuter, to my muscle cars, bikes and to my boats. Is non-ethanol better? I am sure it is. However, I can't justify the cost or having to go search for it. Especially, when I have literally never had any measurable water in my system.

To start, I'm an auto and diesel tech that moonlights doing boat work, so I like to *think* I know what i'm talking about.....though I have been plenty wrong before so feel free to correct me haha! I'm on the same page you are, I run ethanol with no problems. In my experience the biggest thing is the fuel sitting long term. if you use your boat a few times a month and treat it in the winter you likely wont have any issues. Most of what I see is people with big $$$ that have boats as play toys that use them maybe 3x a year, that's when I really see ethanol issues from the fuel sitting in the tank and lack of fuel water separator maintenance.

Had lots of bad exp with eth gas....Not in autos but in things that had seasonal use..Weed eaters/lawn mowers/chain saw/tiller/boat motors...My answer was run all fuel out at end of season...That reduced problems almost to nill...Now that were able to find Non eth gas at a few stations and use it 100% of time and alls OK...But dang the price dff is WOW...Bought some last night Regular unlead $2.65........No ETH $3.99

I run normal 87 as my gas to mix into my bass boat but we run it so much it’s not sitting, my gpa on the other hand runs in once a month give or take and runs non ethanol gas. I switched to normal gas when sleepy joe got us up to 3.40 a gallon for non ethanol

I run some old two strokes that require pouring oil directly into the fuel tank. Never had issues with carbs or fuel system. Does the two stroke oil help protect from ethanol? Would love to see mixed gas added to your experiment.
