I just replaced my old 40/28 Yamaha with a new 60/40 merc 4 stroke this fall. I have been able to get some hrs on it but have been limited on making and long runs or hauling any weight. From the few shorter runs I seem to be getting between 7-8 mpg and under 4gph. Does that sound about right to you guys? I am trying to get a trip planned for spring which will be 150+ miles round trip.
