Thank you all for your comments. By no means should this be the end of the conversation. Please, if you have something to add, let it rip!

When it became apparent that there was an issue with my Rochester Quadrajet carb, I asked a marine mechanic friend to rebuild it. After getting a kit, I gave it to him for the rebuild. He called me to tell me the carb was deteriorated beyond the ability to rebuild. As I needed to use the old one as a "core" exchange I got the old one back. It was disassembled in prep for the rebuild. The innards were a corroded mess!!! The mechanic attributed it to the use of ethanol gas. Hence my post here.

Carl, I had read your post and it was good!!! Your comments are valued and I hope you'll reconsider your original edit.
And I am a member of the facebook group. I guess, having been a member of this forum for a ling time, I felt there were a lot more gearheads here.

As of now it seems the consesus leans toward the use of ethanol gas, as long as it's treated well and moisture content within the tank(s) is eliminated/mitigated. Use of ethanol free is encouraged, but "the proof is in the pudding" in that testing of that gas to ensure its content needs to be done.

"I don't use Ethanol" and I highly recommend you don't either. I personally pulled my two fuel tanks and inpected them before having them cleaned (actually didn't even need cleaning but I did it anyway because they were out), tore down and completely rebuilt my two naval bronze Perko Fuel/Water separator/filters, flushed all of my copper lines, tore down and completely rebuilt my two Rochester Quadrajet carburetors and found no residue from ethanol present anywhere along the system. This was keeping with the previous owners commitment to never use ethanol laced fuel as well. So after reading that you had issues already what can I tell you guys. Go at it cheap or protect what you have, its your choice. How much did those new carburetors cost you?

My 2 cents: The only good gas anymore is aircraft gas. If you want to pay the money. About $5 a gallon, but it is 100/ 130 octane if you need it. These engines don't need it unless you put in higher compression pistons. But it is good gas.
I do recommend taping over your fuel tank vent to seal it up for the winter. That will keep new air from coming in and limit some of the condensation you get. I put a new fuel tank in mine and have a plug in the top of the tank. So in the spring I remove the plug and put a 1/4" copper tube down to the bottom of the tank and pump out any water. Still had problems this year because I bought gas and they had water in their tanks. But I tried.

One of the old Carter AFB carbs I had on my old boat was not rebuildable--it was pin holed enough (thanks to ethanol) that it would run rich at idle regardless of having the idle screws turned all the way in. I rebuilt it a few times with no improvement before tossing it out and going to Edelbrocks.

Here is an interesting and pertinent article which in my opinion was well written. After you get through it waste a little time reading the comments section below the article and you will find that for the most part the masses are asses. George Carlin used to say "Never argue with an idiot, they will drag you down to their level and beat you with experience". I find that sometimes to be true. Anyway, again I advise to stay away from any ethanol in a boat that holds 75 gallons in an aluminum tank, up on blocks, in the elements for an entire winter. Water and fuel don't mix. Fuel does not corrode but water most certainly does. This is the absolute last time I'm addressing this issue. From here we will see who spoon feeds you what...

Followup... (3 weeks removed...)
Had 3 plastic barrels (which had sunflower oil as original contents) that I thoroughly cleaned out to remove any residue. Modified trailer to hold them "rock solid". Picked up 150 gal ethanol free gas from marina having lowest cost/gal. Lot of siphoning into 5 gal cans and then into boat tanks with Stabil added in appropriate amount. And this time I verified gas caps in place afterwords! :oops: Have about 25 gal still left which has been treated and will be used first thing next season.

(Expensive) lesson learned!

I put 1 oz per 5 gallons of 2 stroke oil in the gas it likes the ethanol ,and i get better starting engines ,stabalize your fuel if you arent going to burn it
