Procedure
Fuel System Draining
1. Disconnect the fuel hose from the outboard motor. WARNING: Fuel and fuel vapors are extremely flammable and can be explosive. If fuel is spilled, wipe it up immediately. Keep the fuel tank well away from sources of ignition (sparks or open flames). Perform all work outdoors or in a well ventilated place. 2. Remove the top cowl. 3. Place an approved fuel container under the drain screw and use a funnel to avoid spilling fuel. 4. Loosen the carburetor drain screw. 5. Tilt up the outboard motor until fuel flows out of the drain hole. 6. Leave the outboard motor in this position until all fuel has been drained. 7. When thoroughly drained, retighten the carburetor drain screw securely. WARNING: Be sure to use cloth to remove fuel remaining in the cowl and dispose of it in accordance with local fire prevention and environment protection regulations. 8. Check the drained fuel for the presence of water or other contaminants. If either is present, reassemble the outboard motor, refill the carburetor with fuel, and then drain again. Repeat until no water or other contaminants are present in the drained fuel.
