10. TRANSPORTING

Fuel Line Disconnection

Before transporting the outboard
motor, disconnect and remove the
fuel line.

Gasoline is extremely flammable,
and gasoline vapor can explode,
causing serious injury or death.

• Be careful not to spill fuel.

Spilled fuel or fuel vapor may
ignite. If any fuel is spilled, make
sure the area is dry before
storing or transporting the
outboard motor.

• Do not smoke or allow flames or

sparks where fuel is drained or
stored.

Transporting

When transporting the outboard
motor on a vehicle, perform the
following.

1. Remove the engine cover (see page

38).

2. Set the hoist hooks against the

lifting eyes and hang the outboard
motor to remove it from the boat.
