Fuel Gauge Adjustment?

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!

Send me a picture of this thing if you have one, I thought I was the only
Mon Arc boat owner around.

I don't have this boat, but I have had the problem. Unfortunately, you're
going to need a new sending unit, in all likelihood. Luckily, mine was in a
G3 Pro 175, and the rear of the fuel tank is accessible through the back
hatch (where the batts and bilge pump are) so it was an easy fix.

I too tried to find an easier fix (since I don't like messing with gassy
sending units at all) and even tried replacing the gauge first, but it
didn't function properly until I replaced the whole float/sending unit back
in the tank.

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.

What you say Willis???

Yep, I think you are right, a job I may slide off to the dealer, since
that part of the tqnk is pretty well buried beneath the rear deck.

Thanks for the response!

Hey, no prob. I had hoped that you could find another way around it, but if
all else fails, dealers will gladly book the shop time for you. Mine was
under warranty, but the part and my time equaled less money than the
cross-state trek back to the dealer and the down time it would've required
to leave it, then go all the way back to get it...

Jerry--

I have not forgotten re sending pics. Will do when I can take some
decent ones. Mine is a 1996 Pro 170, and has held up very well to
shallow water abuse--not even a leaky rivet yet.
