6. Nothing wrong with Optimax but some folks want 4 strokes and Merc
needs to have them. Since they are suing Yamaha, they can't get them
there.


Anybody want to wager that in the next couple of months - maybe six at
the most - Verado problems with the D/A interface and their fly by
wire control system will surpass OMCs FICHT problems?

Later,

I don't want to actually bet anything Tom:-) Life itself is a big
enough gamble for me:-) but I'm happy to pretend:-) "yeah my bucko, well
I'll bet ya" the 4 strokes in general will be OK from a technology stand
point.

The Verado is a bit interesting, at least to us anyway, given that they
could have easily & it seems cheaply turned to the alloy GM straight 6
which easily puts out 250+ HP in it's 4 ltr form, no supercharger none
of that. For whatever reason Merc have chosen to go their own way in the
core engine, block etc, to drastically reduce the displacement then make
the HP back up with a supercharger, curious approach we say.
Particularly given the longstanding, hugely successful relationship
between Merc & GM but............. as I said the real technology is all
well known & well tested stuff from the rough & tumble of consumer GM cars.

I think the Verados are now down to a 4 cyl 135HP???? (not sure) if so
then the same "family" style of design might have something to do with
their plans. So now the range is almost completely covered with 4 strokes???

The high revving, multi valve, variable cam timing part is all GM & the
supercharging is also well proven straight GM technology.

The electronics are also pretty tame; these days the GM engines come
almost stand alone, the engine management box & just about all else
needed to run is on the engine itself, not buried off in the cabin
somewhere or a separate box; so that will work.

The fly by wire throttle etc??? GM have had a problem with their
throttle bodies for some time now, they've used an electronically,
direct from the engine management box, operated air bypass for idle
speed control & it's been "problematic", so the fly by wire throttle
control is just more of the same & maybe an attempt to resolve the known
issues with the bypass system??? It's in the cars too of course.

What is for sure is that by going their own way with the core engine,
it's cost Brunswick/Merc a bundle & they're trying to get the price of
all OBs in general up to cover it.

Ficht, Optimax & E-Tec are all dead (E-Tec still born:-)), you can't
run engines at power when lean, a well known & understood fact since the
30s, it's just basic rocket science, the very same problem. So I accept
you don't believe me but do you believe nasa???

Add into all three very poor atomisation from not enough injection
pressure & it's worse.

Then with Ficht & E-Tec add inaccurate loony tunes continuous spark
ignition when in lean mode & it's hopeless.

Then with Ficht & E-Tec add the most dangerous oiling system since VRO
& consumer usage failures are assured.

If the lean mixtures at power don't get 'em, the poor fuel atomisation,
inaccurate spark timing or lack of proper lubrication will.

Been busy today so I'll keep the Krause lie of the day short.

This lying simpleton, after it became clear he was losing a thread
where he was displaying his usual lack of patriotism much less gratitude
for the brave men & women out there risking their
everything, to keep the likes of him safe, he just reverts to type.

But seriously can you imagine this uneducated union thug now claims he
is reviewing universities!!! & wait for it he poo poos the engineering
course!!! this from a lying uneducated union thug who couldn't use a
toaster without a union authorised electrician in attendance.

I've included just one of the followup responses but it was such a bald
faced lie it even embarrassed the rejoinders:-)


I have visited West Point, the Naval Academy, the Air Force Academy and
the sub training facility at Groton. Some years ago, I actually did look
over descriptions of some of the course material at Annapolis and the
c.v.'s of some of the faculty. I'm sure the engineering course material
is fairly rigorous, though it is more "trade-oriented" and did not look
up to MIT or CalTech standards. I mean, if your goal is to be an
aeronautical engineer, you're going to get better training at MIT or
CalTech or at any of a large number of other engineering schools. I
thought the faculty academic credentials no better than what is found at
a typical smaller four year public university. The military academies
turn out military officers with an education, not highly educated
military officers. But that is their purpose, eh?
