My 35 was worse than my 29 as far as gas gauge accuracy... The 29 reading 1/4 gave me some time to locate a pump., If the 35 hits 1/4, it's after it has emptied out, and I am just using the battery to get a reading. I need to be at a pump anywhere near 1/2 on the gauges. Carder

yes all fountains i believe have this problem ... ran from slidell louisiana to ono island alabama (in orange beach) withthe boat at about 45 mph and wen i got there it was just a very lil bit below full

i had the same problem w/my 27.i changed the gas gage and it is better as far as readings......but when at 1/4.....better start looking for fuel.
