KAellis 0 Report post Posted January 21, 2013 My 2006 270 Cruiser has the 6.2L MPI and a 21P Bravo III. I just had a GFS 10 installed and connected to my 740s. With four people on board and at a cruise speed of about 30 MPH the GFS 10 is inidicating a fuel burn around 14-15 GPH. I can get it down to 12-13 by reducing the speed to around 26 to 27 MPH. Anyone else with a similar boat? Does the fuel burn rate seem about right? Share this post Link to post Share on other sites
