Is this E-85 another name for 'gasahol'? That's all we can buy here on the Great Lakes. There is
something in that gas that is continuously clogging the jets of my
4-stroke 9.9 hp Yamaha outboard. Since moving over from a 2-stroke engine, I have had more problems
with jets getting clogged, but that is probably because the
4-strokes are designed to save fuel, and thus have smaller jets.

i was wondering in anybody has used E-85 fuel in their 4-cycle boat
engines.

i know there are very few vehicles that can run on the alcohol based
fuel. I have a friend that has a carburated '76 chevy 3/4 ton truck he
pumps oilwells with, and he says it runs on it fine. but has a bit of
a problem idling without richening up the idle setting.

OTH, I've been to the marina guy who told me, and showed me what it
will do to a 40 horse Mercury. Not a pretty site. The boat owner
thought he'd save a couple sheckels, and filled his 2-stroke with the
E-85. Bad deal. the two stroke oil won't mix witht he alcohol, and
just floats on top like cooking oil. needless to say,it was a burn-out.

Anyhow, I look at it like the E-85 is priced at about $.50 per gal less
than un-leaded, and I dont really see any reason it shouldn't work in a
carburated 4-cycle boat engine.
BTW, Mine is an 83- 140 mercruiser (chevy)
anybody try it, yet?
