Mixing ethanol gas & regular gas

[dnlbro]

I HAVE A PAIR OF 200 E'TECs. [2008 YEAR MODEL] THEY HAVE ALWAYS JUST STARTED AT THE FIRST KEY STROKE.. YESTERDAY, I JUST ADDED ABOUT A HALF A TANK OF REGULAR GAS, FROM A MARINA,TO MY STANDARD, WHICH HAS ALWAYS BEEN ETHANOL GAS FROM A SERVICE STATION.. NOW TODAY MY ENGINES ARE DIFFICULT TO START.. ONE OF THEM REFUSED TO START FOR ABOUT 20 ATTEMPTS.. HAS ANYONE ELSE HAD A PROBLEM MIXING ETHANOL GAS WITH REGULAR GAS?? ANY HELP APPRECIATED..

There should not be any reprocussions when mixing the two fuels.
