for five minutes.
7. Then, push the "UP" side of the power tilt switch,
and raise the outboard motor to the uppermost
position. Hold the outboard motor in this position for

HYDRAULIC PRESSURE CHECK
After bleeding air from the power trim/tilt without
installing on the outboard motor and checking each rod
for proper compression, perform the following operation
in the same manner as bleeding air without installing on
the outboard motor.
– Be sure each rod is extended fully.
– Check the hydraulic pressure both at the upper and
lower chambers.
