Checking the PTT fluid level
Never get under the outboard motor while it
is tilted.
1. Check:
• PTT fluid level

mended fluid.
a. Fully tilt the outboard motor up, and then
support it using the tilt stop lever “1”.

“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.

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.
