I grounded the sending wire and the needle went all the way to empty
from all the way full with about 1/4 tank of gas (verified through the
snding unit cover). I then jumped the sending wire still installed to
the gauge to the +12V side and the gauge started to flutter slightly in
the empty position moving very fast but not far. I also hoooked up the
meter from the sending unit to groung and rocked the boat to see if I
had resistance #1 and #2 to see if resistance changed while the fuel
was moving. It appears the sending unit is good. From what you told
me I expect it is the gauge that is faulty

If you grounded the sending wire at the sending unit and you got the meter
to peg, either your sending unit is bad or there is something wrong with the
ground at the sending unit. You should not have put 12V on the sender wire
on the gauge. The gauge might be damaged now, but hopefully not. Test the
gauge by touching a ground wire to the sending post on the gauge. I hope I'm
making myself clear to you. If not, lets talk some more before you proceed.
