ethanol fuel really can screw up o-rings...fast...

[stackz]

I was out on my neighbor's boat this past weekend and we were actually about a mile or so out fishing and having a good time but then when we went to leave, the engine cranked up for about 40 seconds or so then died and we got nothing. didnt have any tools with us so we had to call for a tow which took about 6 or so hours.

anyway, fast forward to yesterday afternoon and we got together to sort it out. in the end, the pump bulb from the tank to the engine was clogged shut. what was it clogged with you ask??

the rubber seal for the brand new fuel filter we put on that morning before heading out. The e85 he filled up with managed to dissolve it into a gooey mess in just 6 hours so that it clogged the pump bulb up and the engine couldnt get any fuel.

just sharing as I couldnt believe my eyes how fast it dissolved that thing. needless to say, we drained the tank and pulled the fuel system apart to replace all the rubber components with new and glad we did as there were pieces of that stupid seal everywhere including stuck to the floats in the carbs

so yeah, I'm now a firm believer that this crap shouldnt be put in anything that isnt at least retrofitted to use e85 derivatives lol.

So was he trying to get terrible mileage out of his boat or what?

no, just didnt realize until after we filled up the tank at the normal gas station down the street that they had set up some of the pumps for e85.

we simply figured we'd go out and try to use the whole tank that day and then refill with regular gas before flushing the salt water out that night.

1986 yamaha 175hp v6. He takes meticulous care of the thing too. guess him being OCD doesnt hurt that haha.

Interesting. I've heard gas with ethanol in it causes rust to form inside your lines and engine. Not sure if that's true. I guess time will tell.

[ipleadthe5th]

So who's idea was it to put ethanol in a 1986 engine?

[Xentropa]

Gasoline with ethanol aren't meant for old engines. Most engines nowadays should be using copper O rings which wouldn't be damaged by ethanol.......

we didnt run pure ethanol...just e85. and if you read a few posts up, it was an accident but obviously once the gas is in the tank, the station considers it yours

we just didnt think it would create a problem this quick is all. I'm just sharing to let people know it actually CAN happen fast.

I think the big thing is that it was a super cheap rubber gasket on the fuel filter (it was literally like an oil filter gasket) so that may have been why it got ate up sooo damn fast.

Ethanol is just crap, IMHO.

Inefficient waste of perfectly good food.

[boostedcivicsir]

all the wawa's around here have signs on the pump asking if your boat is e10 compatible.

that sux.

[someone else]

When they shifted to 10% ethanol here a couple of months ago I lost 2 MPG on my Accord.


We also had a Civic come in that they had filled with E85 and it had ruined the fuel pump and injectors.

Close enough isn't it? Do other boats run E85?

E85 is NOT reccomended for ANY outboard motor. people are blowing engines left and right from this crap. is a big problem down here because most marinas carry it now. also if you let E85 sit for any extended period of time, is seperates into gasoline, alcohol, and water.

boaters down here are NOT happy with E85. so no, its not just older engines.

edit: marinas have E15 I guess you would call it (15% ethanol), and that is still causing all the problems is seals and seperating after a couple of weeks. oh it also dissolves older fiberglass fuel tanks

People in other countries are dying because of it(can't afford to eat). Good times.

But the technical genius flying around in this thread makes my head spin

[Ekasey]

Just like when you said the OLD TRD CART engine didn;t do 17k on steel valve springs

lol, wtf is that?? hahaha

[xtrac1]

Data log from the Toyota CART engine reving to 17K RPM. I covered up most of the important information because it still might be considered sensitive, even though the series is canceled. Bleh, who cares, its not my ass, lol.
