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. :)



Now wait a cottin' pickin' minute. Your're getting as slippery as Harry.

Nobody talked about maximum speed.

We were comparing fuel burn rates *at* 8-9 kts. and the efficiency of
doing so.
Your Etec, with what? 200hp? is moving a *much* lighter boat at 9 kts,
burning roughly the same amount of fuel as a 120 hp diesel pushing a
30,000
lb boat at 8 kts.

Plus .... (hehehe) let me know when your Etec will need a rebuild. At
6000 hrs, the little Leyman diesel in the GB is about halfway through it's
service life before rebuild according to American Diesel.

I do not dispute that - you are spot on.

I was just curious about max fuel rate on a diesel compared to gas
engine at the same WOT speed.

Let me put it this way - if there was a 200 hp diesel outboard
available, would it be more efficient at 45 mph than a gas engine at
the same speed.

Another curiosity question - what's the reduction ratio on the
transmission for the GB?

No question about it. You can look up the BTU numbers of gas vs. diesel
