Don,
These are '69 engines, non turbo, with 45 injectors unless modified. If you
kept her speed to about 7 knots and with a relatively clean bottom, you
might realize 6 gallons each per hour.

Can anyone give me a ballpark figure how much fuel a Detroit 6V53 will

Hmmmm let's see:
thrust times speed = power required.
power divided by efficiency = fuel consumption rate

We're almost there at the answer....now tell me:
what thrust? depends on the prop size and RPMs
What speed?
What drag?

That's all we need now! :-)

Well I figure there has to be one or two guys around here with twin 6V53s,
or even a single, in their boats, that already know their engines burn 6
gph, 8 gph, 10 gph or whatever. That's all I was asking for. That's
accurate enough for me. Steve (see above) gave me more than expected and
did so without being patronizing.
