I am sure this has probably been answered somewhere before. But, if your fuel pump and injectors can only flow X amount of volume at full throttle, will a boat go faster using real gas of the same octane vs. fuel that has ethanol?

Along with all of the other ethanol related documented issues, I have read that real gas has more usable energy per volume than ethanol. So is thinking correct that at max. capable fuel flow that you will get more performance out of your boat with real gas?

Thanks in advance for your help.

Since the fuel usage with 10% Ethanol is 20% (approx.) higher than with plain gas, I would have to agree with your idea that the power output is lower.

Since the 10% Ethanol gas is not mandated in all States for Marine use, I'll never understand why boat clubs, at least, don't insist on receiving non Ethanol fuel for their members.

Technically yes, the engine will make more power. If it's 1-2 mph I would be surprised.

Wow, can 20% greater volume of fuel burn for ethanol actually be possible? If so, it would really pay to look high and low for real gas at all costs.

If that approximation was close, it would seem that it would really cut down on performance and fuel range.

I'm sure some of the skater guys agree!

I've never run ethanol in my boat. If you travel with your boat plan ahead and I think you can always find non ethanol fuel.

Yes I would estimate 20% seems accurate. Last year Allegheny County, PA mandated 10% in marine fuel and efficiency has dropped off a lot.

I'm sure other people have this question. Does using a product like Star-Tron or buying gas with a Valvtect additive keep the ethanol from causing problems in boats with fiberglass fuel tanks? I'm looking at a boat that might have a glass tank.

If you can find non "E" fuel in central VA would you PLEASE let me know where!!!!! I called a local distributor and they don't know of any.

would you rather run 93 octane with ethynol or 89 non ethynol?
