Gallons per hour

Just checking on what everyone is doing to save boating gas.

Normally I burn from 8 to 11 GPH on my 1988 223LS with 454MAG. I rebuilt the carb and leaned it a bit. I replace the oil with a thicker semi-synthetic. I also replace the 21" pitch 3 blade SS with a 20" 4 blade. I notice a 1 GPH average savings.

This year I played with the trim tabs and the power tilt so that I can maintain a plane speed of 25mph. I gain an additional GPH. I'm happy with the 6 GPH.

Any more tricks, other than stop boating?
