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!

Guy,

I don't think you will find an external adjuster on the fuel gauge, but
I will offer this suggestion. This fall, my gauge stuck on my built in
tank, and because of where it is located I was looking at putting in a
"new" hatch in my boat to get to the sender to take it out. At the same
time, I was having a problem with my motor starting...a 2000 Yamaha 150.
It was suggested to me to put in a can of Seafoam fuel additive to
help with the slow cold starting. Could be a coincendence, but my fuel
gauge unstuck itself after I put in the can of Seafoam. Advance Auto
parts sells the stuff, Wally World doesn't. It would be worth a try.
