525efi Gph

Anyone know the GPH for a a Merc 525EFI, is there a chart somewhere for different RPMs? I saw some spec's from a Fountain test (twins) which said 52gph @ 4000 and 90ph WOT.

That sounds about right. A friend's 500efis burn right about 39gph at WOT(per engine).

My 525 burns about 42 GPH at full throttle.
21 GPH around 3500 RPM.
