The DFI motors do have some inherant lean burn issues. Issues that have been
sucessfully "worked around" by throwing more electronics and technology at
them, but still loom over the design concept as a whole.



The fact that there are plenty of Yamaha and Merc DFIs around and
running well, and that the Evinrude whatever the hell they called now
selling well and running well speaks for itself.

There are dozens and dozens and dozens of these engines powering the
fishing boats leaving the marina where I keep Yo Ho, and I see these
guys several times a week and talk to them. These high tech two strokes
seem to be causing them no more trouble than the four cycle Yamahas and
Suzukis of similar horsepower some of their friends have.


Are you just a simpleton Krause or can't you stop yourself lying?? It
was your pension fund that backed Soros with unionists' retirement
money!!! Have you not noticed that Ficht ****ed US$1.3 billion, that
billion against the wall.

This was during the biggest consumer spending spree in history!!!

Dozens are OK so what?? 1 in 5 failed that was admitted & since then
they've never admitted the failure rate again & they won't with this
latest E-tec try.


Technology is evolving, eh? You build something as best you can, you
test it, and if some units fail, you improve what you are doing and
produced refined product, and that's how the process works.

This is technology that is known not to work, lean mixtures make heat
then cause detonation.

I don't expect you to have any understanding whatsoever but this "is"
rocket science. If you have a burn in a closed chamber such that you
cause a significant pressure rise, then it's very difficult to ensure
that burn progresses in a predictable manner. If the mixture is too lean
then ignition will be spasmodic & the flame front slow, if the mixture
is too rich the burn will be at too low a temp, very dirty & use way too
much fuel. Either side of those two, too lean or too rich & it just
doesn't ignite at all. Even the shuttle only went closed loop very
recently, before that it was all done on calculating the pressures,
temps, etc etc & programing the oxygen & fuel amounts accordingly.

They were & some still are experimenting to discover what everyone has
known since the 1930s & they're using consumers money.


I would
expect that next year's four cycle Yamaha 225 would be more refined than
my 2003 model. And I haven't had any problems with my 2003 model.

Ah more lies you don't own a boat Krause & never have & never will, you
are just a liar.
