Explaining Ethanol in Your Boating Fuel | BoatUS

When fueling make double sure you place the fuel nozzle into the gas tank and not the rod holder!

[@boatus]

Most definitely!

He also failed to mention that many older boats have fuel system components and carburetor components that can be broken down by ethanol. an example is the white colored plastic floats in older mercury outboards. They will swell up when exposed to ethanol and will cease to function, possibly leaving you stranded on the water. be sure to update the components in your fuel system especially if you plan to use any ethanol gas.

How does putting gasoline with more than e10 in it break the law?

[@TheAutoChannel]

All ICE boat motors can run on ethanol-gasoline blends. This has been proven by the Mercury Marine ethanol studies and then the decades of ethanol-gasoline blends in all boat motors in Brazil and Europe. For more information read "Using E10 (and E15) in Your Boat - A Lesson Learned" at www.theautochannel.com/news/2018/09/21/629648-using-e10-your-boat-lesson-learned.html.

Mercury Marine thinks E10(after a transition period) may be the superior fuel to E0 because it keeps the fuel "dry". Water in the bottom of fuel tanks is a problem of E0 gasoline which is why alcohol has been sold forever as gas-line antifreeze. HEET and DRY GAS are two companies who make such products. Mercury Marine, which hosted a Webinar on ethanol myths, noted that ethanol does not "grab water molecules out of the air." It is hydrophilic, which means ethanol holds water. With regular gasoline (E0) as well at E10, the primary cause of water collecting in tanks is condensation on tank walls. But unlike E0, which can absorb almost no moisture, E10 can hold up to half of one percent of water by volume, and the water molecules will dissolve in the fuel. The "solubilized" water will bypass the water separator and burn harmlessly through the engine. web.archive.org/web/20140922142320/dcd96xmek71bc.cloudfront.net/archives/email/Trade/BoatingIndustry/MythsofEthanol-August252011.mp4 The common gasoline of Brazil contains a minimum of 27.5% ethanol and they have the >>very

Interesting info, Dana. Although ethanol-based fuels may burn without trouble, the issue is often related to ancillary parts such as hoses, fuel tanks, gaskets, and the like. Ethanol has been proven to eat through fiberglass fuel tanks and non-ethanol-rated hoses.

@@boatus Thanks for the reply. There was a certain resin in older fiberglass that was incompatible with ethanol but it almost certainly is also incompatible with what goes into today's high aromatic E0 gasolines. Today's gasoline contains high amounts of aromatics, premium gasoline has like 40% BTEX(benzene, toluene, ethylbenzene, and xylene). Also note that today's gasoline has a newer addition of natural gas distillates which coincided with our increased use of ethanol. The US government told engine manufacturers to have everything compatible with ethanol in the 1970s by 1983 if they were not already. I would bet that most of the problems some may have are instead with high aromatics and natural gas distillates but all is being blamed upon ethanol. As evidence I give the country of Brazil who as you now know has 27.5% ethanol in their common gasoline being used in identical boat engines but they have no natural gas distillates nor the need for high levels of toxic and corrosive aromatics since E27 is already super high in octane. Ethanol is much >>>easier

PS I can not edit my posts here. Is this new to KZbin or just your BoatUS's channel doing this? Thanks.

[@boatus]

@@danafletcher2341 I'm thinking that's a KZbin thing, but I'll look into it.

@@boatus Where is that proof? Specifically which rubber, plastic, and metal do you think ethanol damages? There was a brief period in the last decade when a couple of boat manufacturers switched to a certain type of fiberglass fuel tanks that they had not tested with ethanol-gasoline blends. The ethanol did cause delamination of the fiberglass. This is why manufacturers should do sufficient testing, especially since they knew that the composition of gasoline was going to change. So the fault is with the manufacturers, not ethanol. Nearly 50 years ago, Ford had trouble with the Maverick and Pinto cars blowing up when they were hit in the rear. The problem was that the fuel tanks weren't properly placed and protected. No one blamed gasoline for the disasters, they blamed Ford for not testing the vehicles sufficiently. This is the same kind of situation. So knock off the anti-ethanol lies. In December 2011, BoatUS published a story about the Mercury Marine ethanol webinar, in which your company acknowledged Mercury's findings (www.boatus.com/magazine/2011/december/ethanol.asp). If, between that time and now you've been talking money from the oil industry to lie about ethanol, STOP IT!
