'73 non-turbo 337 performance

[Rick Gardner]

Half the route is over water, but it is the last half. I am worried about what you pointed out, no prior history in this particular aircraft.

I am already looking at La Ceiba, Honduras for a fuel stop. We go in and out of there a lot and know the airport staff pretty well so I can usually get a fairly quick turn. This only adds about 20 NM to my route.

My 1974 "G" model I typically fly at 5-6,000 feet at 2400 and 23"mp and true out at 160knots fairly consistent with a fuel burn of 20gph.

I had a 1970E and now a 1980H and find that they are both pretty similar (+/-5kts). I plan for 150kts at 2400/21-22 (at around 6000'avg) and burn 19-20gph. I have flown non stop from KART to KSGJ (900NM) in 6:00 with 30 gal to spare on more than one occasion (150gl total).

The only thing I would say about extended flight (especially over water) is that while I love my fuel computer (and would also never fly without a milti/egt/cht) I belive your regular fuel guages are really more important. On two occasions I have had fuel leaks, one in a tank seal, and one in crack near the sump drain that did not show up on the fuel computer as "fuel burned" . It's nice to know what you are burning, but it's better to know what you really have left in the tanks.
