Mercury Marine Fighting E15
 

Marine industry leader taking action, http://speedonthewater.com/in-the-ne...e-fighting-e15

I'm going to have to sue that Paul Bekemeyer guy that commented.... He said menthol was the way to go for performance so I tossed a bag of Hall's cough drops and a pack of Newports in my gas tank and now the boat won't run....
:lolhit:

No I did not say Methanol was the way to go . I'm talking about Ethanol E85 fuel. I'm running 15 gallon of 93 octane to 5 gallon of E85. I am having good result with that. I will be converting my 850 cfm to run on straight E85 very near future, I would not let my boat sit very long doing that. I in fact use my boat every week. Most boaters use pump gas which has E10 or 10% Ethanol. A few die hards will pay that extra $1.00 plus a gallon for non Ethanol fuel . I have been running E10 pump gas for past 10 years with no problem. E 85 has octane rating of 103 to 105 at $1.00 cheaper per gallon than 93 octane. There is a lot to think about before using E85 . Do some checking E85 fuel or Flex has it pro's and con's most boater cons' but I do see difference the way my boat sound and preforms. https://www.youtube.com/watch?v=5TpSAtqZbLE

Correct, you did not say methanol was the way to go, you said MENTHOL was the way to go.... 3 separate occasions in the original unedited post. Alas, one mention of MENTHOL remains, as noted in the attached screenshot (the edited comment), regarding the race truck. Hair splitting? Maybe.. Autocorrect? Who knows.... But with regard to the E-15 debate, I'll side with Fred K. and Mercury Marine, mostly because they are experts and industry leaders who've more knowledge than I, and back the warranties for the motors I use.

E15 still not going be that much different than E10 . Beside here is Florida nothing but E10. If E15 become a standard Mercury Racing will have to do what other manufacture's do adjust and keep going. They can not say you don't have a warranty be cause you use pump gas. That my friend would bring a big law suit against Mercury. I have used pump gas for over 10 year in my boat with no problem. I will keep using it and have found that it does work good in my case. I will know more when I get carb complete converter. I am not saying everyone should convert and not the fuel for everyone. Ethanol is not the same as Methanol two different fuels, two different calibrations.

I live in FL and right next to a public boat ramp the station sells non E10.

Crystal River there is a couple right on 19, same for down by saint Pete.

Not that hard to find.

Up here in CT, I don't know of anywhere that offers ethanol-free fuel. Luckily I have not seen E15 yet, but I'm sure it's only a mater of time...

The problem with ethanol fuels is they attract and hold water and can cause corrosion and they are jus plain and simple hard on fuel systems. Just like whipple and kiekhaefer stated unless you are completely converted or for special events you are asking for trouble. I personally will never use E85 and try to avoid ANY ethanol fuels in anything I own. Yes E85 has its place in the performance world but mainly in high HP street cars and race cars NOT in a marine environment. Most average boaters don't know and don't care about the difference they just put gas in and go and that is what causes the problems and damage. As for voiding the warranty and lawsuits etc. I agree with MERC in that you put the wrong fuel in your boat and you're a grown adult and don't read the pump etc its your baby. When we used to do a lot of endurance testing for Merc and they were in Stilly here in OK we went to the plant a few times and I got to see how and where these things were thrashed on and see the multi engine dyno cells where they would flog multiple engines for hours or days on end. I've watched them tear down engines in tear down rooms and go through looking for any sign of any little thing to show a problem. Ive seen what Merc does to sort an engine/drive package and there are certain things you can and can not do plain and simple so put on your big boy pants and accept your adult responsibilities for your adult decision to put the wrong fuel in your boat and void your warranty. Or you can make the decision to learn and be an adult and put the right stuff in your boat.

ethanol blends gather water and the unbelievable wreck they make of carbs with jets, fuel bowls, fuel filters and engines is terrible. "Stabil" stuff might help some but doesn't solve it.
Plain gasoline without ethanol stores and runs better in boats that aren't always seeing use and see long storage intervals.
Plain gasoline has more energy per gallon and gets better MPG.
Plain gasoline doesn't run up the cost of FOOD on our tables from corn to beef.
Plain gasoline doesn't need Government subsidies and MANDATES to SURVIVE in the marketplace, because it is GOOD ALL BY ITSELF and everybody knows it.

I LIKE E85 for race engines...I am converting to Flex Fuel gasoline-E85 on my street/race turbocharged car because it IS race gas...but has the above limitations, that I can DEAL with on my car with small 22 gallon tank, NOT on my BOAT with 340 gallons that could go sour and wreck 2 engines/injectors out on the water!
Gasoline for boats should be PLAIN GASOLINE, it is best and safest and stores best BY FAR, and Mercury Says So Too.

^^^ agreed sir

High octane numbers don't do a lick of good if a winter's worth of condensation is mixed in with the fuel.... Real gas for my boat, please.
Additionally, running your motor on LOWEST octane that doesn't cause spark knock is generally recommended- higher octane allows more performance in motors that are built for it, but no added benefit for a stock motor designed for 87.... My lawn mower really doesn't need 105 octane corn blend in the tank.

How can we join Mercury Marine's effort in fighting E15?


I'd like to Support Mercury Marine in this effort.

Granted I don't have a 300 gallon fuel tank in my boat but you let any fuel gas or ethanol set it will all go bad. I have used 93 octane which has ethanol in my boat for over 10 year with out any fuel related problems. Of course I do use my boat every weekend or more. There is a lot of pro's and Con's and most boaters do use the ethanol blend fuels ect for a few. And for the few that don't like ethanol in their fuel Mercury has a cure in a bottle, You family friendly Walmart has it in the oil isle so check it out or pay more money per gallon for ethanol free fuel ether way ethanol is not going away but at sometime in the future the ethanol free fuel will be.

Like SS930, I cannot find ethanol free gas near Houston. All marinas and car gas stations I have seen are E10. So far no problems in my boats or cars but I use blue Sta-Bil on every boat fill up. Anybody know anything about "GULF MARINE 100 with ISO BUTANOL " on one of the comments? Is this a viable alternative to booze gas?

I think I would disagree with you here. The stoichiometric value for each fuel is as follows:
Gasoline :14.7:1
E10: 14.08:1
E15: 13.79:1

Max power air fuel ratio:
Gasoline 12.5:1
E10: 12.0:1
E15: 11.75:1

Almost any marine motor that was originally setup for standard gasoline will have drastic issues with E15. Even with a typical margin of 5% which would be high, your still leaner than peak power of E15 and just under E10. If the calibration, or carbs are not adjusted, you can see at least a 50deg EGT increase during peak RPM levels, further taxing the engine components. You then have to factor in the detonation level, as you've increased temps, leaned the motor out, the detonation level gets closer and closer. The results are lower power, increased fuel consumption and higher level of emissions as the volume over comes the benefit of the ethanol.

We had to significantly richen our calibrations up for E10 to make the motors live, E15 would do the same. But when we do this, we lose HP. OEM auto makers state that this could hurt 2 out of every 8 vehicles on the road today. The fuel systems simply were not built for ethanol in most applications. Only the later engines have proper injectors, orings, seals, gaskets, pumps..... And then only some boats have tanks that can actually withstand the massive corrosion issues associated with the ethanol fuel. E10 has been bad, E15 will be worse.

WG,
Is correct, in fact I've found a gas station over in Satellite Beach, (15 miles away) that has 93 Octane PURE Gas! And man does my new 572 love it! Go to:

and enter your state and it will tell you where the non E10 stations are. It seems very accurate.
