I have a similar engine question. I have looked at several 423 Classico OAs.
Then engines vary from 120 Fords to 235 Cummins to 350 Cats.

I see some listing claim to cruise at 14 knots, but many show 8 to 10 knots.
I assume the 14 kts are by the large Cats, but what kind of fuel consumption for the extra 6 kts? And, can one run the 350 at slower speed (10 knts) and get the efficiency of the smaller engines. I like the extra power available when needed for current and wind, etc. but am happen with the slower cruise most of the time.

Any suggestions appreciated.
