to the
battery terminals.
7. Reverse the PTT motor leads between
the battery terminals when the tilt ram is
fully extended, and then reverse them
again when it is fully compressed.
NOTE:
• Repeat this procedure so that the tilt ram
goes up and down four to five times.
• The sound of the power trim and tilt motor
will change when the tilt ram is fully
extended.
8. Check the fluid level again when the tilt
ram is fully extended. Add sufficient fluid,
if necessary, and then repeat step 7.
NOTE:
Repeat this procedure until the fluid remains
at the correct level.
Bleeding the power trim and tilt
(built-in)
1. Loosen the manual release plug by turn-
ing it counterclockwise until it cannot be
turned further.
2. Fully tilt the outboard up, and then
release it and let it lower by its own
weight four to five times.
3. Tighten the manual release plug by turn-
ing it clockwise.
4. Let the fluid settle for 5 minutes.
5. Push and hold the power trim and tilt
switch in the up position until the out-
board is fully tilted up.
6. Support the outboard with the tilt stop
lever, and then let the fluid settle for 5
minutes.
WARNING
After tilting up the outboard, be sure to
support it with the tilt stop lever.
Otherwise, the outboard could suddenly
lower if the power trim and tilt unit should
lose fluid pressure.
