Bad Gas?

[Baldo]

I'm looking for ideas on solving a sputtering problem
On my 2011 22ve 70 hrs. I put gas from a few canisters
In this weekend. Everything seemed ok for about 1/2 hour.
Then when I went to throttle up it began to sputter almost like
It was miss firing. I dumped a can of sea foam in and it seemed to
run ok for a bit again. Then the sputter came back

I had a situation similar to this pop up on me on my first trip to Powell this year. Throttle up, then splutter, almost die, accelerate again... the cycle would just repeat itself. I was able to get a Gatorade bottle and sump the fuel out of the fuel filter canister, and I was surprised by the amount of water that was found. After I did that, it ran just fine with no problems. It's pretty easy to tell if water is in the fuel, it will be sitting on the bottom of the bottle (or whatever you use to sump it with) and is a slightly different color.

I pulled the canister right off and removed the gas. Never really payed attention to color
When I put it back together it ran ok for a bit.

What was the reasoning behind using gas from canisters? Ethanol which is in almost all gas now sucks, as you're finding out, because it absorbs water and lowers the octane BEFORE it separates from the surrounding fuel. And it will only separate AFTER the rest of the fuel is saturated with moisture (10% ethanol = 10% water absorption by volume... 10 gallons of fuel, 1 gallon of water BEFORE it shows up visually...). To help with your potential water in fuel situation, run some 2 cycle synthetic engine oil mixed into your fuel tank at 1oz per gallon to help lubricate the injector tips and fuel pumps. Run the tank dry or just suck out the fuel in the tank now and start over.

Wow... I will be on the look out for these symptom when I'm out... does it simply collect in the fuel filter??? I change mine annually so maybe that helps.. which I'm sure most people do too, right?... Also,Would it be better to run the highest octane gas to keep this from happening or is it simply becuase all fuel has 10 % ethanol now?

Our boat has had this same problem all year and have not been able to use the boat because of it..It has done this the last few years and the dealer has fixed multiple things attempting to fix it and the last fix seemed to have worked last year, but they have finally narrowed it down to the computer and they are going to see if they can reflash it otherwise its $1600 for a new computer.... it's an 05 22ve and its getting sold as soon as this problem is fixed done wasting money on Tige... Hopefully yours is just water

I just bought a 2006 22VE (90 hours) in June. The tank was empty when I bought it and I filled it with regular 87 octane with 10% ethanol. I had random missing issues all summer. I changed the fuel filter, ran injector cleaner and sea foam thru the system with no improvement. Finally I started using 92 octane non-oxygenated (no ethanol) fuel and the problem has gone away. Is the solution that simple?

Could you have accumulated water in your fuel tank? If the tank isn't kept full, repeated warm (day) and cool (night) cycles will accumulate condensation in the tank over time which will settle to the bottom - where the fuel pickup is. As BoatWakes mentioned, it might be a good idea to drain that tank completely, all the way to the bottom, and use a Seafoam-rich mixture of NON-ETHANOL gasoline to fill it back up. The Seafoam will help draw out any remaining water, and the lack of ethanol will help prevent moisture from creeping back into your fuel system.

You'll end up buying a tank full of gasoline eventually anyway... so this is no "extra" money spent and might reveal the problem. Just an idea....

No, its not that simple. Your engine and fuel system is designed to run on the ethanol blended fuel. The mere presents of ethanol in the fuel is not an issue and doesnt create any driveability issues. The problem is from lack of preventative maintenance that comes with toys that sit, and ethanol fuel. it will also create issues in older boats with fuel components not designed with ethanol in mind. The symptoms you experience are a result of a break down in the fuel system, but the root cause of the degrading fuel system, is the long term use of ethanol.

Lots of myths regarding ethanol fuel.

1- Ethanol actually increases octane
2-Ethanol blended fuels is designed to last 16 weeks if you need it to last longer just add seafoam
3- Ethanol does not absorb water, ehtanol is miscible in both gas and water. In presence of water ethanol can leave the gasoline and dissolve into the water, again seafoam will fix this
4-Ethanol does not hurt modern engines or components there designed for it.
5- 10% ethanol fuel is max rating and most time is no where near that composition. Also Ethanol evaporates very quickly (think hand sanitizers). So how much is really in your tank?
6-Water and gas dont mix. whether or not you have blended gas in your tank or not, these are boats in a wet environment, we surf and the vent is on the regular side and takes on water. Very easy to get water in your fuel while surfing. Also many of us have aluminum tanks which act just like a big soda can with a nice cool beverage stored inside on a hot humid day. Humidity just loves to precipitate in our tanks.

Moral is... Just use seafoam and you will never have a problem (or Yamaha ring free as it is similar and more concentrated so it goes further).

Seafoam is different from Stabil?

Seafoam is different from Stabil?

Yes. StaBil is a fuel stabilizer. Seafoam is an engine and fuel system cleaner. It also claims to be a fuel stabilizer, but I don't rely on it for that function.

I use Seafoam in every gallon of fuel that goes into my Tige, jetskis, ATV's, chainsaw, generator, weedwhacker... basically everything except our car and minivan. And since I've done so I've found my engine problems have gone way, way down. I don't need to clean/rebuild carbs nearly as often, plugs are cleaner and don't foul, cylinders and pistons don't carbon up, etc. The difference is most pronounced in two stroke engines but I've run Seafoam in my PCM EX343 since the day I got it.

I also use Seafoam in an extra-rich mixture to decarbon two-stroke engines. The smoke is incredible and the results are too.

I am usually very skeptical of "magic potions" and snake oil and such. But Seafoam is the real deal. I strongly recommend Seafoam and buy it in the gallon cans at NAPA. I use about 0.5 ounce per gallon in four stroke engines and double that in two strokes. (As a side note: I measure Seafoam into my gas cans using an old 32 ounce StaBil bottle because StaBil has that handy measuring/dispensing system integrated right into the container. You can't get them mixed up because StaBil is red and Seafoam is clear.)

I also use StaBil, but only for overwinter storage. In that case both Seafoam and StaBil are in the tank.

Sta-Bil offers more.then 1 formula

Seafoam stabilizes fuel for 2 years. I have tried it. It works well for stabilization. I put it in my snowmobile every year and no issues with the fuel the next winter. If I do not use it, well I have to drain tank and all that fun stuff as the machine will not run on it.

Are these the myths or the fact? And I completely disagree with the closing moral, thats why I am asking.
