TRIM AND TILT
SYSTEM DESCRIPTION
SYSTEM DESCRIPTION
The hydraulic unit consists of a manifold that con-
tains all valving, fluid reservoir, pump, motor, and
cylinder.
The hydraulic unit pivots on the lower thrust rod
and the piston rod attaches to the underside of the
swivel bracket.
As the cylinder begins to extend, the first 15° of
outboard movement is considered the trim range.
As the cylinder continues to extend, the remaining
50° of outboard movement is considered the tilt
range. Total outboard movement is 65°.
The outboard can be manually raised or lowered
through its entire trim and tilt range by opening the
manual release valve a minimum of three turns.
When this cycle is complete, the manual release
valve must be closed and tightened to a torque of
45 to 55 in. lbs. (5 to 6 N·m) before normal opera-
tion can be resumed.
A trim gauge can be purchased for the outboard.
The gauge's sending unit is located on the port
side of the swivel bracket.
When the outboard is tilted for long periods of time
or trailered in the tilted position, the outboard's
weight must be mechanically supported. The out-
board is equipped with trailering locks. When they
are engaged, the cylinder must be retracted until
the trailering locks are firmly seated on the stern
brackets.
