When taking outboard motor from 
package or removing outboard motor 
from the boat, never release the lock 
lever. If the lock lever is released, it 
will very easy for the clamp bracket 
to spring up to the tilting direction 
because it is not fixed.

!

�������

Never attempt to disassemble shock 
absorber of gas assist tilt system. It is 
dangerous because high pressure gas 
is included in the shock absorber.

When trailering the outboard motor 
should be in a vertical (normal running) 
position, fully down. Trailering in the 
tilted position may cause damage to the  
outboard motor, boat, etc.
If trailering with outboard fully down is 
not available (the gear case skeg is too 
close to the road in a vertical position), 
fix the outboard motor securely using a 
device (like a transom saver bar) in the 
tilted position.

TRAILERING

!

�������

Do not go under outboard motor tilted 
up even if it is supported by support 
bar, or accidental fall of outboard motor 
could lead to severe personal injury.

!

�������

Close air vent screw of fuel tank and 
fuel cock before carrying or storing 
outboard motor and fuel tank, or fuel 
may leak, potentially catching fire.
