Default How far would you drive for ethanol free gas

My F250 has never tasted ethanol since I bought it new 3 years ago. Now I have moved my boat and ethanol free gas is an extra 12 miles each way by car or 5 miles each way by boat. I am now thinking of going to the easier, cheaper standard gas with 10% ethanol. Is the ethanol issue big enough for this extra effort?

I don't think it would be worth it, at least not in season when you are burning it up fast. My boat rarely goes a week without being run year around and I've had no problems with the 10%.

This. If you run your boat often and change filters frequently the 10% has little to no ill effects. Just be sure your getting gas from a busy source, not some Mom & Pop gas station with no activity.

I have never ran ethanol free in the Tahoe. The boat about 90% of the time is ethanol free when I can find it close. I wont go far to get it and will never run 15%.

If your using your boat regularly, I would not drive a mile or pay .10 extra per gallon for ethanol free fuel. On the other hand, if the boat gets used infrequently and the fuel sits in the tank and in the engine for months on end, IMO going the few extra miles for ethanol free fuel is worth it.

IMO, burning fresh ethanol fuel in a modern outboard is no problem at all, however letting untreated ethanol fuel sit in the tank and engine for months is a valid reason for concern.

walmart or local autoparts store sell a great additive that cures all ethanol problems for less than $10, treats 100 gallons or more ,
i use it when the season is ending and i know the boat will sit for a few months,
also that STA-BIL fuel treatment is pretty good for gas engines that will sit for a long time ..

Most of the ethanol issues happened when ethanol first became mandated.

Most fiberglass tanks in use at the time had gelcoat (or equivalent) that dissolved after prolonged exposure to alcohol.

Metal tanks (and carburetors, injectors etc...) had 'gum' buildups that were also susceptible to alcohol exposure.

As long as the motor was running, this gunk would remain in solution with the gasoline and would run through the combustion process. When the engine was switched off the material would redeposit and clog the system.

With metal tanks, it was advised to run as continuously as possible for several hours or until your tank was as empty as practical, whichever came last and refill. Running 1/2, sitting then 1/2 again etc, could prolong the agony and may result in permanent deposits.

With fiber-glass tanks you were likely to be screwed no matter what.

Since your boat is new you are likely to be okay if you follow the regimen above for metal tanks I think you will be fine. The current f/g tanks should be using materials that are alcohol resistant.

Good luck!

Your biggest risk is the fact you have only been using non-ethanol gas. The result is you have deposits in your tank and lines the alcohol in the ethanol will clean out and send through your engine. Depending on how old your boat is then the ethanol may or may not have a negative effect on your tank, lines, etc. If you decide to use ethanol I suggest you change your gas/water filter before you start, then consider changing all of the easily accessible filters soon thereafter, because there will be deposit accumulation which will be turning loose. I have used both ethanol and non-ethanol over the 8 years life of my engine without a problem, but I have primarily used ethanol for the last 6 years. Any time I felt like my rig had sat too long, and especially when my Kolor Kut test showed my fuel was saturated with water I just pumped it out and put it in my truck. However I rarely keep more than 20-25 gallons in my 60 gallon tank. Good luck with your fuel management.

Straight from YAMAHA:
"All current models as well as most engines built since the late 1980’s have been designed with fuel system components that are tolerant to fresh fuel containing ethanol up to 10% (E10). Outboard fuel systems can still be affected by: water, dissolved gum, varnish, corrosion particles, and dissolved resins that E10 fuel has cleaned from the distribution system and your boat’s fuel tanks."
How old is the tank?

Like others have said, Ethanol, besides being hygroscopic, will cause sediment in your tank to become dislodged, not the end of the world, as a 10 micron Racor and the 2 Micron under the cowl should keep it out of the VST and injectors. Keep close eye on your filters and monitor the performance of your engine, any degradation in acceleration will be indicative of a clogged filter.

One more point to consider, your fuel lines (and ball) from the tank and to the motor, are they ethanol rated? Ive experienced some failures with Quicksilver components manufactured within the last decade that have been exposed to E10. Knowing here we are talking about a YAMAHA, my point is that even modern marine quality components may be susceptible to the effects of ethanol if not explicitly touting their resistance.

If your lines are old perhaps it is time to consider replacing if they are not too difficult to reach. Fuel lines, from my experience, that are not ethanol rated will degrade from the liner inside the line and clog filters downstream, it will be noticeable. The lines then swell and can be susceptible to chafing, leakage, and permeation. All bad things on an enclosed space.

I personally don't run ethanol fuel in my boat, actually when I used to trailer before moving to living on the water I would go out of my way to get Rec90, simply for piece of mind. If it were unavailable, I would do as I described and upgrade my fuel system, add some stabilizer if the boat were to be sitting for a while, and be done with it.

Don't understand the thinking behind " water in the gas is no good for the boat but OK for the truck" Hate your truck much ?

I run my truck in the water a lot less than I do my boat. I also don't let the gas sit in the tank as much, I usually fill my truck up at least once a month (I work from home and we drive my wife's civic everywhere without the boat, so my truck is only used to tow the boat or an occasional errand to pickup something large)

E10 attracts water due to the ethanol in it, and most places cite a shelf life of 90 days. My boat gets 4-6mpg depending on speed and a 61 gallon tank. If I fill it up for a trip that's canceled due to weather, that's 250-365 miles I have to drive to burn all the gas. If all we have planned is going on dinner cruises, island hopping, or fishing within 10 miles of the dock, it takes forever to burn all the gas, certainly not something we can do within 90 days.

After shelling out over $60k for my new boat, I don't mind the extra expense of ethanol free fuel. You never know when something might happen where you might not be able to use the boat for an extended period of time. In the event something prevents me from using my boat, I will have peace of mind knowing I have ethanol free fuel in my boat.

Our new boat has run nothing but ethanol gas. We burn it pretty quickly.

I see no problems with doing so, especially without the varnish build up from running non ethanol. I would be more concerned had only non ethanol been run in it for long periods.

Bayfly quote...The quote was that it was determined that there was water in the boat fuel, so pumping it out of the boat and putting it in the truck just sounds like a jack ass move

Since your Yam F250 is a late model engine... IMHO its not worth the drive to find non-ethanol in season. You are likely burning through too fast for a water problem and the extra savings in cost will provide that much more incentive to use your boat more.

However, during the winter or if it has not been used for awhile, sure go ahead and fill with rec-90. As always, be sure to change your water/fuel separator filter regularly and inspect...

A little perspective, approximately 6000 miles of tidal coast line in New England. Thousands and thousands of powerboats can be seen operating on the ocean, bays, coves, rivers, lakes and ponds that cover and surround the region. Aside from specialty gasoline, only sold in small quantities, at $10 or more per gallon, there is no ethanol free gasoline to be purchased at the pump across the region.

My current engine, a 2004 Yamaha F225 with 1201 hours, has burned approximately 9000 gallons of E-10. Each year, my boat sits on the hard from November-April with 150 gallons of E-10 on board, in temperatures that can range from the 70sF down to -10F with nothing but a healthy dose of ordinary Stabil (RED) added to the E-10.

Not claiming that ethanol issues do not occur but I do know for a fact there are thousands of boaters in the Northeast who aside for treating fuel when going into storage, don't sweat E-10 other then anual changing of fuel filters & water seperators that should occur anually regardless of E-10 or no E-10......

According to www.pure-gas.org there are about 80 ethanol free stations in New England...

I only buy ethanol gas. It gives me an excuse to use my boat more

"honey we have to go, my gas is getting old" and off we go

Why can't we get an ethanol free gas station south of Pompano in Broward!?

The secret sauce recipe to using E10 is use Startron and Ring Free Plus.

Startron fixed the water issues and prevents corrosion among other things like helps with carbon issues. Ring Free Plus also helps with cleaner combustion and corrosive affects of ethanol which will keep your VST filter from clogging due to corrosion.

Lots of folks using this combination and not having any fuel issues.

Like other say, first time use can clean up the fuel gum residue in tank and lines, so use a good new filter and recommend a 2 micron Racor inline to catch anything before it gets into the engine and change first time after 50 hours, then 75 hours after.
