When transporting and storing the outboard motor, close the air vent screw and fuel cock to prevent fuel from leaking. EMU00326 q TRAILERING OUTBOARD MOTOR The motor should be trailered and stored in the normal running position. If there is insufficient road clearance in this position, then trailer the motor in the tilt position using a motor support device such as a transom saver bar. For further details, consult your Yamaha dealer. w 8 Never get under the lower unit while it is tilted, even if a motor support bar is used. Severe injury could occur if the outboard accidentally falls. 8 USE CARE when transporting fuel tank, whether in a boat or car. 8 DO NOT fill fuel container to maximum capacity. Gasoline will expand considerably as it warms up and can build up pressure in the fuel container. Install the top cowling. q w 6) 7) 605011 1 Water surface 2 Lowest water level 4-4 E EMK26010 Lubrication 1) Remove the spark plugs, and spray a 10 second spray of Yamaha Stor-Rite Engine Fogging Oil into each cylinder.
