I honestly don't know what my range is. I assumed a 1973 40hp Johnson would not be too efficient. Do you use a plastic or metal 6 gallon tank? Sally
I have averaged 8.7 mpg in the 300 miles I have data for with a 1986 Mercury 35 on my 13. The spread was 7.1 to 10.4 mpg. I carry two 6-gallon tanks if I need the range, the original metal and a plastic, the metal in the stern and the plastic in just behind the forward locker. I just use the plastic if using only one since it can go in stern or forward and metal tank and tank pad are starting to show wear after almost 30-years in fresh and saltwater use.
