E15 comment period ends today

Posted on

Today is the last day of the comment period on the petition to the U.S. Environmental Protection Agency requesting a waiver to allow ethanol gasoline blends of up to 15 percent.

The comment period was slated to end May 21, but the additional time allowed boaters, marine industry employees and other concerned parties more time to submit comments to the EPA.

Growth Energy, a pro-ethanol lobby, is the group that requested the waiver.

The National Marine Manufacturers Association, and other industry stakeholders, have called for a science-based review of the request by the EPA in order to ensure that increased levels of ethanol would not harm boats, marine engines and other affected equipment.

The EPA has said it is required to make a decision by Dec. 1.

    Ethanol is also bad for my aircraft engine as I burn autogas I have to buy fuel at gas stations that still have ethanol free fuel.
    Please do not deny the public the opportunity to purchase ethanol free fuel.

    The current level of ethanol has had a costly adverse affect on exisitng gas pwered boats. Increasing the level of ethanol will only make the cost of boating and repairs higher.

    Please do not permit or require E15 for marine and hand tool use. The ethanol in these fuels degrades fuel tanks,and fuel lines, and when the engine is not used for 2-3 weeks, the build up of residue in the carburator, injectors, on spark plugs, and nozzles drives huge maintenance costs. As corn based ethanol is already proven to be a costly alternative, please do not make the problem worse.

    As members of the marine industry, we implore the EPA to heed the warnings and advice of experts in the industry when making your ethanol recommendations.  We are aware of the need for energy inititatives, but NOT at the expenses–literally–of current boat owners.  The problems caused by ethanol in marine engines are real and are costing customers of an already beleaguered industry more money than they have to spend on repairs.  This will only further discourage people from boating at a time when we definitely need them to be enjoying their boats as often as possible. 
    The industry will be proactive in working with you on alternatives–we are fortunate to have a good representation within your realm.  Thank you for your consideration.

    As a naval architect, and the owner of a boat that is twently years old, it is not only imperative for the EPA to reject ethanol gasoline blends up to 15%, but it should be required by the federal government that fuel suppliers continue to provide pure gasoline to marinas and fuel docks.
    I have repeatedly seen and experienced the problems surrounding ethanol blended fuels in marine applications all too often.  The ethanol causes the seals and gaskets of older engines to dissolve, resulting in the leakage of fuel, both into the boat which is not only extremely dangerous, but also into the exhasut system which intern ends up in the atmosphere and waterways.  Furthermore, the leakage requires the fuel to be cleaned up and disposed of properly, which not only doesn’t always happen (usually ending up in the local garbage can and trahs dump).  Ethanol also causes the varnish and residues held internally within engines to release.  These foul the engines further causing them to loose efficiency, causing them to burn and bleed more fuel into the envirionment.
    Fuethermore, the fuel leaks caused are inherently extremely dangerous and can be catastrophic!
    Boats are not like cars which refuel weekly, and many with internal fuel tanks carry large fuel capacities which always stand for long periods of time.  This causes the water in the fuel to separate and to sink to the bottom of the tank where the engine fuel pick-up is.  This results in the water being pulled into the engine, doing damage and resulting in less efficient engine operation, thus causing more unburnt fuel and oil to be emitted in the exhaust.
    Additionally, some boats that have built in fiberglass tanks are having the ethanol attack the resin used in the tank cosntruction compromising the integrity of the tanks.
    More ethanol, much less any ethanol in marine fuel just doesn’t make sense for the sake of the environment or for the food materials (corn) that we use unwisely.

    I run an independant laboratory testing lubricants and fuels. We receive samples from individual boat owners, fleet operators, and marine surveyors. We see the most serious fuel problems from gasoline powered boats that have recently purchased gasoline containing ethanol. A large percentage of recreational boats are used very infrequently and fuel can remain in tanks for over a year. Even several months in humid conditions causes water to be absorbed by blended fuels. Separation of mixture into an alcohol rich heavier layer with high water content and a top layer of primarily petroleum gasoline and lubricant (when it has been premixed) stratifies in the tank. This also occurs rapidly if blended gasoline is added to tank containing unblended gasoline and a layer of separated water at bottom. When engine runs even a short time on the water/alcohol mix containg minimal lubricant, engine damage occurs. Any benefits resulting from running autos on blended fuel must be weighed against problems caused for mariners and other users of 2 cycle power equipment.

    I’d fully expect that the EPA working group recommendations will be followed.
    The E-interests have not solved pollution, performance and economic issues.

     I would like to take the time to go into details but I am too busy explaining to my customers why there outboards do not work as well (or at all) as they did 3 weeks ago.  The ethanol additive has had a detriemtnatl effect on antique boats, (namely gas tanks, fuel systems and engines) as well as the small carburated o/b engines.    If adding ethanol, find a suitable stabilizer to add to offroad fuel as well.
    Gotta go.

    It has been established and proven for many years now that ethanol alchohol is corrosive to many metals and will degrade some soft parts of a fuel system intended for gasoline. What scientific study do we need to prove that a more concentrated level of ethanol will also be detrimental?

    A marina on a local lake got a tank of E-85 mixed into his shore side marine pump. The resalts were about 10 boats quit running in just a few minutes and would not restart had to be towed back to shore. I have had to replace the neddle & seat twice last year in my Johnson carb after only a few hours of running regular pump gas E10. I talked to severial other dealers and service people and they all told me about the current E10  ethanol ploblems it is what is causing the tips of the inlet needle to swell and stick you can remove it for a couple of hours then put them back in and it will work for a short time. Fuel line on outboards are getting hard from the current fuel what will E15 do ?. What about the damage its doing to the outboard motor main bearing seals
    Lets keep the gas clean of ethanol we don’t need the damage it dose to motors,fuel lines, fuel tanks.

    The marine sector and the marine engine is subtantially different from the automotive sector.  There has been a rapid turnover in the fleets of cars and trucks but the marine fleet does not have the rapid turnover that the motor fleets do.  Many marine engines and fuel system components are not compatible with ethanol blends.  The enviromental benefits of the use of ethanol blends in marine engines  the majority of operation of is in a fuel rich condition is limited if any at all.  The use pattern of boats is significantly different that motor vehicles.  Boats may set for months between uses whereas cas and trucks seldom do.  During that time the vessel will continually absorb atmospheric moisture..

    E15 gasoline will be very distructive and damaging to engines and marine businesses.

    Stop the craziness …. ethanol is a misguided, wasteful, failed, feel-good experiment. Face it. 
    Ethanol consumes more energy to produce that it is capable of providing as a finished product. It is a thermal net negative.
    Fuel economy is reduced in engines using it, even in concentrations as low as E-10, often reduced by as much as 20%. This is true for land based engines as well as marine engines. Older marine engines are still being damaged, and sometimes just plain destroyed, by it. Even if not damaged, performance is reduced - across the board.
    It requires dedication of cropland that should be producing food for people and livestock, and it requires massive quantities of irregation in the growing.  
    The direct cost of food, including meats, milk, eggs, grains, veggies, plus their delivey costs are increased by the very exiesence of ethanol.
    E-15 can only make matters worse, not better. This makes no more sense than trying to spend our way out of the recession, drink our way sober, or eat our way thin. Wake up people ! !

    I started working on outboard motors in 1960, when we had good quality gasoline and poor quality of oil.  Situation has changed to the direction of good oil and bad gasoline.  With E10 I have run into a lot of problems with fuel lines and gaskets inside of carburetors.  I’m starting to see problems with crackcase halves on old motors leaking.  I think it is because alcohol is the solvent for the old sealers used  several years ago to seal the crankcase halves.  I’ve always had performance problems with E10 some motors when warm seem to vapor lock and will not run on it.  The last 4 years I have run into a lot of water in gas tanks.  It seems that E10 will grab hold of more moisture then it can absorb.  Who is going to tell us how to over come these problems with E15?  E10 is bad on some aluminum carburetors.  What is E15 going to do to them?
