2.

Press the power trim and tilt switch “

”

(up) until the outboard motor has tilted
up completely.

3.

Pull the tilt support lever toward you to
support the engine.

WARNING

EWM00261

After tilting the outboard motor, be sure
to support it with the tilt support knob or
tilt support lever. Otherwise the outboard
motor could fall back down suddenly if oil
in the power trim and tilt unit or in the

power tilt unit loses pressure.

CAUTION:

ECM01640

Do not use the tilt support lever or knob
when trailering the boat. The outboard
motor could shake loose from the tilt sup-
port and fall. If the motor cannot be trail-
ered in the normal running position, use
an additional support device to secure it
in the tilt position. For more detailed in-

formation, see page 61.
