I have not had a problem (yet) I have used the same station and pump for years. to be honest, I think ethanol has been in the gas for years before anyone told us about it....

I have twin outboards and use 93 octane. Wonder if I should just use 87.
My boat runs fine. I do change the filters two or three times a season because of the build up in the filter. I have had good luck with regular fuel. From what I have read and been told, as long as I don't leave fuel in the carb when the bait is being stored every few weeks, that it should not have any issues. Ethonal builds up around the little pin holes in the carbs, making the pin holes even smaller. As long as there isn't fuel sitting there, I should be good. Theoretically .
Plus I'm cheap. Non ethonal fuel must contain gold in it, because that seems to be the way it's priced, and when I buy 50 to 60 gallons for a trip, every cent counts.

If the motors are not built specifically for higher octane, your just wasting money buying the high octane stuff. Check what the manufacturer recommends for them. If they are not high compression engines they shouldn't need high octane. Several engine builders these days are building high performance/low compression engines to run on regular pump gas. I had a motorcycle once that I did a few performance upgrades to. Ran like a scalded dog on 87, put 93 in it and it ran like poop. Low compression engine.

If the operators manual says 87, 93 is just throwing money away.

Just my .02 worth..

As I had understood, Ethanol fuels tend to rob the engine of efficiently. Reducing your mpg- this is what we observed in automobiles at one time.
I typically run ethanol free fuel in our boat, but as long as you run it often and use an ethanol treatment, I don't see any problem with it. Although, other than connivence of not having to look for a gas station selling ethanol free marine fuel- doesn't having to buy fuel treatment and changing out filters more often negate some of the savings you are attempting by buying regular fuel?

Default Hoses, fuel pump, carbs problems w/ethanol

If you have an older outboard, built before ethanol, the rubber parts will not stand up to ethanol. I forget the exact year, but if there is any question, either
1-Use only 100% gas
2-Replace the hoses and fuel pump diaphragm, clean the tank(s) & keep them full.

Pay attention now or pay $$$ later.

Ethanol SUX, except it does send me a lot of new customers for replacing fuel hoses, fuel pumps and cleaning carbs.

I use 100% gas in my outboards, lawn mower, chain saw, generator, pressure washer, my 1999 Chevy Van, (16% better fuel economy with 100% gas), etc.

The engine that's on the back of my 1998 Mako boat is a 1997 Mercury 225 EFI. Right now everything is running fine. I will be changing out the fuel/water seperator here in the next week....Damn the government for the Ethanol crap.

I attempted to do exactly what you are/were attempting to accomplish with the following results:

2004 24 Cape Horn twin HPDI Yamaha's swooped into the circle K and filled her up 215gallons worth of 10% ethanol. This was in 2007 when it first started "but I still knew better" however we had a great plan! Two of my fishing buddies were gonna leave navy point around 4pm on a Tuesday evening and head SE to about 14mi south of the squiggles. Sword fish all night in the pocket of cobalt, catch the morning bite fish as late as we could sparing about an hour to race home with a box full of fish then off to work the next day. And that we did! We caught everything except a bill filled the bags and turned her north around 3pm. About 5:30 pm we were still in about 800ft of water and the wind noticeably picked up from the west pretty sporty, pretty much took us down to about 10-12knts. Next thing I knew it was getting dark ice was going quickly and one of my buddies had to work a side job that night at around 8pm. So I told them to buckle their chi straps we got to get in. Big rollers about 5 2sec apart up and down hard for the next 6-8 miles both speakers fell out of the top and were dangling we whip out a pocket knife and cut them down and hammer down again. Up and down hard, beating our asses to death but we pressed on. Next thing I knew I see the V bracketing on the left side of my top break loose and fly to the aft cockpit... Hell with it bloody knuckles! About another 7 miles "still in 800ft of water the left side of the top breaks at the transition and is now dangling... Welds cracked to death top is shot so I back down to about 12knts and we got her on the trailer with about 1/4 tank left.

Four days later my boat is at blue coral getting a new top. It took them about three weeks to finish my top. Then we are ready to go mash tunas again! I went to the "good gas" station in Milton and filled her up again. Off we went this time to the nipple auto piloted out in great seas just about to drop lines and the port engine stalls. I fire it back up and we press on. About an hour later we are fishing in the trough in about 3-5 boat is rocking and port engine downs again. Fire it up not to worry cause we got another motor... Keep on fishing trolling it wasn't a big issue. We start home and I hammer down... Both engines bog and go into recovery mode... 9knots from just south of the nipple, luckly we had plenty of beer... Get home around 1am about a 12hr boat ride. Boat guy comes over and drains out about 15gallons of the ugliest stuff I've ever seen in a tank. It smelled like fish grease. The mechanic takes out his lighter "away from the boat of course" and the stuff doesn't even fire off with a lighter. Long story short you never know what might happen cover your ass it cost me right at 8k to replace all the injectors, all six fuel pumps "HPDI has three each" , filters pretty much everything but the tank and the lines...

Yep I use ethanol fuel with sta-bil, never an issue but I also go through a bit more fuel than most so it doesn't sit very long. The longest mine set this winter was about 3 weeks but I still had no problems.

I've been using real gas usually but tanked up with ethanol-laced gas last time because it was convenient & we were going to do a lot of running around. Ended up not running around as much as I though we would, so a lot of it's still in there a couple of weeks later.

Will topping the ethanol-laced fuel already in the tank with real gas help matters any?

Always run ethanol gas. Change and clean filters every 50 hours. Never had a fuel related problem caused by ethanol in any boat I run. Run a 700hp Corvette on ethanol gas and it gets used less than the boat.
