Uh, E-85 isn't 85% alcohol, it's 85% gasoline!

Where does that link say ANYTHING about the oil not mixing with E-85
properly? All you've given so far is hyperbole. I've not seen one tiny
bit of convincing evidence that backs up your contention that oil won't
mix with E-85. Do you have any? What's more, E-85 actually runs cooler
than unleaded gasoline, that actually being a good thing for your
engine. It also burns cleaner, another good thing for your engine.

wrong-o.

89.5 octane is an approx 10% alcohol blend with the unleaded gas.

E-85 is 85% alcohol with 15% fossil fuel.

Tell you what. I think you should load up your outboard with E-85 and
the typical recommended 2-stroke oil mix.

Go to the lake with my blessing. Have fun and enjoy the day! No need
for a tow rope even if it doesn't take up much space in the bow
compartment.

Go in peace. ; )
