What kind of mileage range are you guys seeing with h-51 Yamaha 90 two stroke combo. It seems that 18 the gallon fuel tank was standard on the older boats. I know it’s a loaded question with all the variables (tackle, fishermen,wide open throttle etc.) but just a general average fuel range. Not much info out there on subject. My glass rig has 36 gallon tanks and It’s not unusual for me to travel 80 miles round trip. Looking at adding an Xpress h-51 for times and places I prefer not taking the glass rig. Thanks
