Fuel level

Check that you have plenty of fuel for your trip. A good rule of thumb 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 main switch to the “” (on) position and check the fuel level. For fuel filling instruc- tions, see page 53.
