Using Marine PRO for treating ethanol in my 2017 Mercury Optimax 250 XS Outboard [SOLVED]
I run a 2017 Mercury Optimax 250 XS outboard on my fishing boat. I don’t always have access to ethanol-free gasoline. When I have to use ethanol fuel, will Sea Foam Marine PRO work as an ethanol treatment?
Hey Andrew. Something represented as “ethanol treatment” might cause a false sense of security. Be aware that adding a fuel treatment isn’t going to change ethanol from what it is. Just know that when combined with water, ethyl alcohol has corrosive potential in a fuel system. To answer your question, Marine PRO’s petroleum ingredients will add protective lubricity to fuel system parts. Another key is to manage your fuel in favor of frequent replenishment. Also keep in mind that your Optimax is built to handle E10 (10% ethyl alcohol). No matter what gas you’re running in your Mercury, remember that Marine PRO is always working to clean and lubricate your fuel system.
