inside of the through tube and to the hy-
draulic steering cylinder rod or steering ca-
ble.

Checking the PTT fluid level
Never get under the outboard motor while it
is tilted.
1. Check:
• PTT fluid level
a. Fully tilt the outboard motor up, and
then support it using the tilt stop
lever
“1”.
b. Remove the reservoir cap “1” and O-
ring “2”, and then
check the fluid level
in the reservoir.
Before removing the reservoir cap, make
sure that the PTT ram is fully extended.
Otherwise, fluid could be expelled forceful-
ly from the unit due to internal pressure.
If the fluid is at the proper level, a small amount
of fluid should flow out of the filler hole when
the reservoir cap is removed.
c. If the fluid is below the proper level,
add the recommended fluid.
d. Install a new O-ring and the reservoir
cap, and th
en tighten the reservoir cap
to the specified torque.
Checking the power trim and tilt unit
operation
1. Check:
• PTT unit operation
a. Fully tilt the outboard motor up and
down
a few times and check that it tilts
up and down smoothly. Check the
PTT fluid level if the tilt operation is not
smooth.
The motor will have a consistent sound when
operating properly and there is no air in the
system.
