I wouldn't get too worried. The other guys numbers are "guesses" based on cruise and idle as they don't have flo-scans.
Not guesses....they are based on the published numbers from CAT..+/- 3%......which are based on the motors being properly propped to achieve WOT of 2800 RPM.
RPM ---300HP --- 350HP -- 385HP --- 420HP
2800 ---15.6 -----18.0 ---- 20.1----- 22.9
2600 ---12.2 -----13.9 ---- 15.4 -----17.3
2400 ----9.4 -----10.8 -----11.8 -----13.3
2200 ----7.3------ 8.3 ----- 9.0 ------10.1
2000 ----5.5 ----- 6.3 ----- 6.8 -------7.8
1800 ----4.1 ----- 4.7 ----- 5.1------- 6.2
1600 ----3.1 ----- 3.5 ----- 3.7 ------ 5.9
Average burn numbers for my CAT powered 410DA, calculated over the entire 2007 season, are much lower.....in the area of 17GPH for BOTH motors.
