Oh Gene!!!! Read this, "cruising" @ 35MPH on his claimed E-Tecs

Come

on Gene embarrass yourself as usual & say you think this is for
real.
I'll send it to the contender people for you:-)


Well, once again Karen is "blown out of the water" with actual facts.

Here are the performance results with twin 2006 250hp E-TECs that only
consume 20.7 gph at about 35 mph on a heavy 30' SeaCraft, less than 11
gph per motor, just like Gene said.

That is so much better fuel economy than Karen's contention that a
boat
that size should burn 30 gph at 35 mph!

Is the data for one motor or both motors?

My 200 HP Optimax takes 19 GPH at WOT .. so 37 GPH for 500 HP wouldnt
be bad ...


It would be unbelievable. Did you see the Bass and Walleye Boats results
I posted a while ago? etec didn't use less gas than Optimax or HPDI.
These numbers would have etec producing 50 hp more per motor at the same
fuel usage than your Optimax.

Maybe Bill Grannis will provide his opinion about the veracity of the
numbers.

All other ETec fuel data I have seen so far the ETec got their ass
whipped by the optimax (even HDPI).

Thanks for stating the bloody obvious about his fuel claims Matt & for
risking the pack turning upon you:-) it's not much fun I can tell you.

& thanks as always to smart Del; you're a straight shooter & appreciated
for it, even when you need to shoot me from time to time:-)

Runaway william & tommy too loony for school are not interested in
actual figures they're interested in selling overpriced, heavy, slow
thirsty engines at hugely inflated markups:-) Now add the Ficht historic
reliability question & you can see why they need to talk BS.
