If you want to know exactly what the fuel consumption is on the F70 install a NMEA 2000 network and plug it in to a compatible Garmin, Lowrance, Raymarine MFD.
I’m not sure how many different size tanks are in these 17.8’s. Mine has a 23. I never leave the dock without a full tank and there is no way for me to fish a normal amount of hours a even come close to running out of fuel; no matter how hard I run.Tell us brother!
What was d difference in performance on ur boat with scd vs nrs models? Only others i have tried was the red model n it was sub substandard, cavation massive.I think that’s the semi clever (sc), my boat didn’t like it. Mine is the same diameter and pitch, but the NRS model. It has significantly better bow lift with the NRS.
