I had a pisser of a time with my 90HP Honda 4 stroke outboard this past
spring. Clogged passageways, rough running, crapped up lines etc. Cost me
over $500 to have repaired, and it had to be done a second time!!(No cost)
My mechanic (Chris) was quoted in the Boat US article and I guess the
problem comes about when the two gasolines are mixed together. Forms a
sludge and just makes a royal mess!
Also, had to replace a gas tank on my two month old weed whacker because the
fuel dissolved the seam of the plastic gas tank. It looks as if it just
melted the glue(?) bedcause it ran down the outside of the tank. Looked
like hardened epoxy.
It was not a very pretty Spring. Got into boating about 3 months late. A
lot of fellows in the boat club had similiar troubles.
Hope for better this year.

I'd be inclined to blame the ethanol for liberating accumulated varnish
and sludge in a seasonal-use engine than for precipitates.

Definitely the FRG tanks made before the mid 80s are begining to show
severe attack and 'penetration/leaking' .... and you definitely do not
want free gasoline in the bilge of a boat ..... goes BOOM. The
insurance underwriters that follow the boating industry are currently
'frantic' about the MTBE to ethanol changeover.

That might be a problem with an older engine, but this engine was only on
its fourth season. I had run it out, fogged it and stabil'ed it each fall.
It was the combination of the fuel types. Boaters all over the stases of NT
