Most marinas around here sell ethanol free gas. You might check, if you have an on water fuel station. Expect to pay more both at a marina and a regular station.

Whether it's recommended for your outboard or not, I think that ethanol-free is better for boats. A boats' environment is typically exposed to more water and humidity (obviously) than your car. That ethanol is hygroscopic, meaning it's actively trying to acquire water, and water in the fuel is a big problem for boats. Years ago, steel gas tanks were fairly common in boats. If you find one today, it's almost certain to be all rusty inside. Ethanol was a bad idea from the get-go, for several reasons!

All engines were made to run on alcohol and because your mfg. suggests using non-ethonol you are going to have to use additives, any auto store carries them

I have used E10 in my Yamaha motors since 1994 and have put close to 3000 hours on them. I have never had a problem and Yamaha, in the same paragraph that you are referring to, states that their motors ARE calibrated to run on E10. The manual does not say use only E10.
All of the components are designed to handle E10. The biggest issue you may encounter is when the gas is stored in the boat for a long time. This can cause what is known as 'phase separation' which is not good.
So here's my advice: Use E10 as long as the gas is not to be stored for a long time and when expecting to store gas (such as over the winter), make the drive to obtain and use non-oxygenated gas. This is a good compromise.

Exactly. Marina fuel is free of the water based solvent ( alcohol) because they are near water and many tanks are submerged in water in the docks. They do it to avoid water in fuel.

I have been thinking the exact same thing as you stated in this post.
Non ethanol for storage.

Non ethanol for storage.
The only tricky thing is getting the tank almost empty before filling with the non Oxy fuel.
I have been using this program successfully for a long time.

Thanks, MH! Your response gives me confidence without mentioning that dufus idiot!
Around here it’s just called “Recreational Gas”. Usually 91 octane. Just search for that in your area.

I know that but if the local gas stations don’t carry it at the pump a commercial distributor is a good source. I had to buy mine from one in Oregon. Few gas stations in my area carried non-ethanol fuel at the pump.

I've practically worn out a 70HP and 15HP Yamaha four stroke and have NEVER used
anything but standard ethanol-infused regular gasoline. I do, however, use the Yamaha Ring Free
additive and usually a storage additive with each fill up. This is on the advice of Yamaha technicians;
consequently, I can troll all day at 700 RPM with the 70HP without building up carbon deposits
and damaging the engine. My buddy and I put hundreds and hundreds of hours on our small
Honda and Mercury four strokes with no problems, as well.

If you have access to Buckies Super Service stations, they sell non-ethanol gasoline. I do not know if all of them do, or not. Just Sayin...RJS

Most Murphy's gas stations at Walmarts have ethanol free fuel at their pumps. You might check them out. Usually .40-.50 cents a gallon higher than regular gas.

Catfish, off road diesel doesn't have higher sulphur anymore, dyed red to indicate no road use taxes paid on that fuel.

Thought it’s a perfect paradise and Oregon is the worst place on planet.
Just what I read in the past. Or is it different when you need non alcohol fuel? It figures.
