I have used regular old ethanol fuel in my last two boats (four strokes)because no one in San Antonio carries ethanol free. Knock on wood, no problems yet.
There's three stations in SA that sell E0. Murphy's in Schertz, Murphy's in Universal City, and Murphy's at Loop 410 and Military Road. I fill up the boat and truck when headed to the coast.
 
Rudy's

I winter in Port Aransas Texas. On the main drag in Corpus there is a BBQ and gas station called Rudy's. They sell non-ethonal gas, I always carry and extra 5 gal jug and when I drive by I fill it up. Corn juice ate up a diaphragm on one of my fuel pumps.
 
I run cornfuel in my '09 Opti 150. It starts every time I turn the key even after I let it sit 6 months. I will continue to run it without worry...

With that said I think ethanol did in my old Yamaha 130. But that was several years ago right when blended gas came out.
 
I try to use ethanol free when I can. If I leave my boat on the water, I fill up at Redfish cove, but at $4.00 gallon, makes it a tough pill to swallow. If its on the trailer, use the regular ethanol blend but religiously use Mercury Fuel stabilizer.

Old boat did the same but used ringfree and never saw a fuel or filter issue.

Pretty sure the new inline carbon filters keep alot of water from penetrating fuel cells. Use my boat every other week till hunting season.
 
Only issue I ever had with corn fuel was an old 2001 mercury, and it wasn't engine issues it simply melted the fuel lines so crud accumulated in the filter and clogged it up. Replaced the fuel lines and primer bulb and was back in business. I used all my current boats constantly year round so never had an issue otherwise. I think people are a little oversensitive with the whole thing. If you use your boat once a year you're probably better off not owning a boat and just charter what you need when you need it.

I trailer my boat from San Antonio to Corpus. I have been stopping at Rudy’s bbq to fill up with non-ethanol fuel for about $2.95 (I believe). I am running a 96 Johnson 115. I have been told these older carbureted motors were not designed to run ethanol fuel. I figure it’s worth the extra money to help avoid any fuel related problems. Also, I run my boat regularly at least once a month but usually every 2 weeks or so.
Which Rudy's? 151?

I know the one in corpus has it At least last time I was there it did.
 
I run regular 87 octane ethanol blend gas in all my outboards (1968 6hp Johnson all the way up to a 2010 250 Yamaha four stroke and a couple older two strokes in between) along with lawn mowers, weed eaters, blowers, pressure washer etc and have no ethical related issues I don't get what the big deal is about, I will add the mercury quickleen fuel treatment if I know the fuel will set up for a while. I have bought a few used boats that had the cheaper gray marine fuel line and the internal liner had separated causing the filter to clog up, changed fuel lines and filter and was on the way. The big thing is use your motors more than a few times a year and use quality fuel lines, primer bulbs, filters etc and it should not be problem.
