New to the site and to E Tec..thanks for the add...New to me 2014 90Hp E Tec....Ethanol blended fuel is the only fuel available in my area ...ugh... What is the best way to run this type of fuel in this engine ? Best addative?..fuel /water seperator recommendations...any help would be appreciated. TIA
This is my experience - I have a 2016, 150 E-tec that I bought new - I run non-ethanol free, but if you can't my suggestion is add a fuel stabilizer (I use marine sta-bil), and be sure to check your fuel/water separators occasionally. Racor makes a fuel/water separator with a clear bottom for you to check for water. A lot of folks use Seafoam as an additive with good results. It does contain alcohol so be mindful of that. You also have a fuel/water separator on the motor that you should change occasionally as well. Hope this helps and good luck!
There is no trouble running E-10 fuel in your E-TEC as it is made for it. Problems occure when the fuel is not fresh, is left untreated for months inside the engine, and if moisture or humidity build up in the gasoline then a corrosive mixture of water and alcohol settles out to the bottom of the tank. The process of water and alcohol (ethanol) combining and setttling is called phase separation and that highly concentrated and corrosive mixture is what causes expensive problems.

The factory recommends that a properly trained technician service your Johnson or Evinrude outboard motor. Should you elect to perform repairs yourself, use caution, common sense, and observe safety procedures in the vicinity of flammable liquids, around moving parts, near high-temperature components, and working with electrical or ignition systems.
The information offered here is only general in nature and should not be construed as complete factory approved procedures, techniques, or specifications. Always use the proper service manual for your motor, up-to-date service literature, the correct tools, and have an understanding of how to proceed with troubleshooting and repair methods. If you are unsure or uncomfortable with a procedure, a situation, or a technique, enlist the services of a factory trained technician.

There is no fuel/water separator on a 90, except HO models. Hopefully one is fitted in the boat.
