Checking the PTT fluid level
Never get under the outboard motor while
it is tilted.
1. Check:
•PTT fluid level
Below the proper level → Add the recom-
mended fluid.
a. Fully tilt the outboard motor up, and
then support it using the tilt support le-
ver “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.
TIP:
• 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.
• If the fluid is below the proper level, add the
recommended fluid.
c. Install a new O-ring and the reservoir
cap.
