TRIM AND TILT
MODES OF OPERATION (THREE PISTON SYSTEM)
Manual Release – DOWN
When the manual release valve is opened and the
outboard is manually tilted down or trimmed in,
fluid flows from the bottom of the tilt cylinder (in
the tilt range), or from the bottom of all of the cylin-
ders (in the trim range), and past the manual
release valve.
Fluid flows from the bottom of the tilt cylinder (in
1
the tilt range) to the top of the tilt cylinder. The
excess fluid, equal to the volume of the piston rod,
is vented to the reservoir.
In the trim range, the fluid from the bottom of all
three cylinders is vented to the reservoir, except
for the amount required to fill the top of the tilt cyl-
inder.
After opening the manual release valve, close it
firmly. The manual release valve must be closed
to enable the trim/tilt unit to function.
