You boys with fiberglass tanks better forget about using them. The author of this article said that the resin used in those tanks will pretty much melt right into the gas and then glue your valves, etc. together. Also, the fiberglass will eventually weaken to the point that it gives.

According to the author, even aluminum tanks will have problems before long... :-/ :-/ :-/ :'( :'( :'(

I don't understand how the guy can end the article with an optimistic attitude???

By the way, he also says to not top off your tanks for winter, but to do the opposite. Run them dry. This new gas won't last to Spring. You'll have to throw it out anyway, so don't bother putting it in for storage...

Thanks for the article Skools. Any advice???

Well thankfully none of us have fiberglass tanks and they are mostly in older boats.

There was a guy here when this first came out with a Bertram size? But to tear up the teak deck and replace the tank was $10,000!! :o

As far as the gas not lasting all winter, I started my boat and it is fine so far!! My friend filled his tank added stabil and used it all with out any issues?

But I have always tried to get rid of all my gas before winter, for 15 years now!!

Any who the biggest problem with this gas IMO is that it mixes with water and there for makes your water separator useless! Unless you have a ton of water.

10,000 to tear up the deck and replace the tank? You should just save the 10g and repower with diesel, if your tanks haven't deteriorated yet.

Re: Lesson's from Ethanol's Freshman Year
 

If it's that damageing to the tanks, what is the possibility of deterioration of the fuel lines in older boats. This may be the reason for the grey colored gas lines and not the older black ones. ???

76 that wasn't my boat, it was a guy from a near by mariner.

tsubaki, yes it its all the old hoses up! Thats why you shoul replace all your hoses ASAP if you have any problems.

Re: Lesson's from Ethanol's Freshman Year
 

Now my question is. If the newer gas mixes readly with water, will this increase the possibility of an engine running too lean?

Re: Lesson's from Ethanol's Freshman Year
 

um if it's this rough on boats think of your cars and lawnmowers plus our antique cars on man they will be doomed

Current marine hoses are rated for alcohol. In fact, I just replaced all of my hose last night. It was 3.09/ft for 3/8ths inch inboard hose. The gray vs. black might be an outboard vs. inboard thing. I used inboard hose, it was black. The gray outboard hose might have better UV resistance.

I cut open a piece of 5/8 USCG approved hose the same type of the 3/8 you got (pretty red stripe and all) and the interior is lined with the same material as the grey hose.
I know one thing the black hose really absorbes the heat from sunlight. While installing some yesterday at about 80 degrees laying on the deck the hose was too hot to hold in your hand, next to it was the grey and it was as cool as the deck.
