TRIM/TILT
7. With the rods extended fully, operate the power tilt
motor to extend the each rod until relief valve opens
again. Operate the power tilt motor to compress the
each rod and be sure that the rods compress (page
19-31).
If the rods extend and compress fully, go to the
hydraulic pressure check (page 19-33).
8. If the rods do not compress after the step 7
operation, operate the power tilt motor to compress
each rod (page 19-31) while pushing the piston rod
B [1], and check whether the rods compress.
If the rods extend and compress fully, go to the
hydraulic pressure check (page 19-33).
9. If the rods still do not compress after the step 8
operation, loosen the manual valve [2] and
compress each rod. Tighten the manual valve
securely again. Operate the power tilt motor to
extend the each rod fully, and then operate the
power tilt motor to compress the each rod and check
whether the rods compress fully (page 19-31).
If the rods extend and compress fully, go to the
hydraulic pressure check (page 19-33).
10.If the rods do not compress after the above
operations, perform the following.
– Disassemble and assemble the power trim/tilt (page
19-19).
– Bleed air with the power trim/tilt not mounted on the
outboard motor (page 19-31).
Air bleeding with the power trim/tilt on the outboard
motor
Perform the following procedure after bleeding air
without mounting the power trim/tilt on the outboard
motor and after checking the hydraulic pressure.
1. Install the power trim/tilt on the outboard motor
securely (page 19-9).
2. Push the "UP" side of the power tilt switch, and raise
the outboard motor to the uppermost position.
3. Remove the oil tank cap [1], and check whether the
ATF is at the upper limit [2] of the oil filler port. Add
ATF if necessary.
