Fuel/additional additives???

[kcg202champ]

Gas these days with "10%" ethanol (water) crap is horrible for these outboards... now my question is... i have been running 90octane "ethanol free" gas since owning my boat.

I've owned my boat for 4 years now, yep it's an oldie but dang goodie, 2000 model Champion, with a 225 efi Mercury on it.
Anybody who has ran the regular 10% ethanol added gas and even the "ethanol free" gas see any kinda difference in performance? Do you guys run additional additives like, startron, seafoam, staybil, lucas oil, etc. see any kinda differences?
All and i mean ALL info would be bery appreciated!!

I have run 87 E10 for over 10 years. It isn't horrible on outboards. It is horrible on older fuel lines which clogged up outboards. I use Mercury Quickcare for the ethanol and Quickleen to deal with carbon build up - 1oz of each per 5 gallons of gas.

I have never had an ethanol or any fuel related issue since using it. Before then there were two boats that I needed to replace fuel lines but that was it.

I run Seafoam and Lucas ethanol treatment.

I have just always ran 10% ethanol. Never used any additives

Im using 87 octane and adding Liquid Performance
Ethanol Equalizer. Awesome stuff ..completely cleaning the carbon build ups and what is a most amazing dissolving water in the tank and everywhere.
Run much smoother the engine
I strongly recommended to everyone

ran my 99 merc 200 efi on ethanol fuel from 99 until I sold it in January 2020 with zero issues. Those fuel treatments are jokes. do some research and look what is in it... alcohol or kerosene etc.
