When transporting and storing the outboard motor, close the air vent screw and fuel cock to prevent fuel from leaking. 000859 EMU00326 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. 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. This can cause fuel leakage and a potential fire hazard. 4-2 E cC Do not use the tilt support lever/knob when trailering the boat. The outboard motor could shake loose from the tilt support and fall. Grease the spark plug threads and reinstall the spark plug(s) and torque to proper specification. (Refer to "CLEANING AND ADJUSTING SPARK PLUG". ) 2) Turn the engine over with the stop lanyard disconnected to work the fogging oil into the piston rings. This prevents the formation of condensation. For models with a remote tank, it may be necessary to manually override the control unit to completely fill the engine main tank. (Refer to "CHANGING GEAR OIL"). Inspect the oil for the presence of water which indicates a leaky seal. Seal replacement should be performed by an authorized Yamaha dealership prior to use. (Refer to "GREASING") EMU00352 Cleaning and Anti-corrosion Measure 1) Wash down the exterior of the outboard with fresh water and dry off completely. 2) Spray the engine's exterior with "Yamaha Silicone Protectant" (Part No. LUB-SILCNE-13-00). cC Do not spray when the engine is running. Also, do not spray near the silencer and oxygen sensor cover or into the engine. [. . . ] If a question or problem arises regarding warranty, first contact the owner of the dealership.
