Is it possible to adjust a console mounted fuel gauge for greater
accuracy? My tank is an 18 gallon plastic, builtin, on 17 ft. Monark
Pro 170 with a 50 hp Mercury 2-stroke.
It reads "Empty" with 14 or 15 gallons left in the tank!!

I'd like to avoid disassembling the tank to get to the internal float
or sensor because its well beneath the rear deck. I'm hoping there's
a simple external calibration adjuster of some sort....

Thanks!
