I put about 30 hours on my new Parker's engine before the season
ended,
and burned about 55 gallons of gasoline in the process, according to
the
flow meter. How much gas did you burn in your string trimmer?

If my math is correct that's about 1.8333333333333 GPH. My guess is
that
you didn't get that barge above hull speed much.

That's just about what Mrs.E.'s boat burns running wide open.


Just out of curiosity, what's the speed WOT?

8-8.5 kts. 120hp 28,000 lb boat (empty) more like 30-32k lbs. loaded.

I was just trying to point out how misleading Harry's reported "numbers"
could be to some. They may be accurate for how he happened to operate his
boat last year, but the numbers should not be construed as being typical
for
that engine or boat. All you have to do is look up fuel burn rates versus
RPM for the Yamaha 150 four stroke.

Well, here's an interesting data point.

On my Ranger, with my sexy high tech ETEC engine, at 9 knots, I burn
just under 2 gph.

Curious huh?

Yes. Touchdown for diesel power!

Similar amount of fuel used, moving a much heavier boat with much less
horsepower.

Case closed.

Well, not really.

I can't see your GB going 50 mph on the way to the fishing grounds.

Case reopened. :)

I wonder what the burn rate would be at the high end of the RPM range
for, say, 45 mph on a go fast diesel powered boat.

Bet 'cha it's about the same.

Then again, how would I prove it. :)
