I just realized as I was reading more about it, one of the test boats (on the GPH/performance charts) listed it at approx 7.8 GPH at an idle speed of 3 to 4 mph. That's about what I average on my tritoon with 115hp at 22mph
! I'm pretty sure at around $78,000 each, GPH isn't really a big concern for those who have quads on a 43' Midnight Express!
