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 instructions, see page 45.
