Got in the boat this weekend and when I fired it up, it was showing
*below* E on the gas gauge. I never run it much below just a tick
under 1/4, so I knew something was wrong. I filled it up at the gas
dock, and it's still showing hard below E, just as far down as the
hand can go.

Does anyone know the resistance value used for the float sender unit?
I know that the sender has a potentiometer (a "volume control") that
varies its resistance value between full and empty. The gauge sees
that resistance, and turn it into a reading. I just need to know what
values to look for so I can figure out if the gauge or the sender is
bad.

Thanks in advance for any help.
Short the sender to ground. The gauge should read full. The wire wound pot
is about 200 ohms, I think.
