Fuel level

Be sure you have plenty of fuel for your trip. A
good rule is to use 1/3 of your fuel to get to
the destination, 1/3 to return, and to keep 1/3
as an emergency reserve. With the boat level
on a trailer or in the water, turn the key to "
(on) and check the fuel level. For fuel filling in-
structions, see page 51.
