EMU29153
Checking power trim and tilt system
WARNING
EWM00430
● Never get under the lower unit while it is
tilted, even when the tilt support lever is
locked. Severe injury could occur if the
outboard motor accidentally falls.
● Make sure no one is under the outboard
motor before performing this test.
1. Check the power trim and tilt unit for any
sign of oil leaks.
2. Operate each of the power trim and tilt
switches on the remote control and en-
gine bottom cowling (if equipped) to
check that all switches work.
3. Tilt the outboard motor up and check that
the tilt rod and trim rods are extended
completely.
4. Use the tilt support lever to lock the motor
in the up position. Operate the tilt down
switch briefly so the motor is supported
by the tilt support lever.
5. Check that the tilt rod and trim rods are
free of corrosion or other flaws.
6. Activate the tilt-down switch until the trim
rods have retracted completely into the
cylinders.
7. Activate the trim-up switch until the tilt rod
is fully extended. Unlock the tilt support
lever.
8. Tilt the outboard motor down. Check that
the tilt rod and trim rods operate smooth-
ly.
NOTE:
Consult your Yamaha dealer if any operation
is abnormal.
