After tilting up the outboard motor, be
sure to support it with the tilt stop lever.
Otherwise, the outboard motor could sud-
denly lower if the PTT unit should lose
fluid pressure.
2. Remove the reservoir cap 2, and then
check the fluid level in the reservoir.
w
Make sure that the trim and tilt rams are
fully extended when removing the reser-
voir cap, otherwise fluid can spurt out
from the unit due to internal pressure.
NOTE:
If the fluid is at the correct level, the fluid
should overflow out of the filler hole when the
reservoir cap 2 is removed.
