TRIM AND TILT
SYSTEM DESCRIPTION

SYSTEM DESCRIPTION
The power tr im/tilt hydraulic system is completely
contained between the outboard's stern brackets.
The system consists of:
• Electric motor
• Oil reservoir
• Pump manifold assembly
• Cylinder body assembly
Optimal boat and outboa rd performance can be
achieved b y adjusting (trimming) th e dire ction of
outboard propeller thrust. The trim range (first 21°)
is primarily made by the trim cylinders.
Outboard mo vement be yond the trim ra nge is
considered tilting . Tilting of the outboard may be
desired in sh allow water d rive app lications a nd
trailering/storage. The tilt cylind er moves th e out-
board through the tilt range (final 54°).
A tilt relief valve limits the propeller thrust load that
will be supported by the unit in tilt range. As pres-
sure in creases, the out board will tilt down to the
top of the trim range.
IMPORTANT: When in tilt range , make sure
water is available to gearcase water pickups.
Manual Adjustment
The outboard can be ma nually raised or lo wered
through the en tire trim and tilt range by opening
the manual release valve a minimum of th ree
turns. The manu al release valve mu st be closed
and torqued 45 to 55 in. lbs. (5 to 6 N·m) to hold
the outboard in position and before normal opera-
tion can be resumed.
Trailering Bracket and Tilt
Support
Use the trailering bracket to support the outboard
when trailering in th e tilted position . This bracket
protects the hydraulic system from damage.
Tilt the outboard up fully, engage the bracket, then
tilt the ou tboard down until the b racket is firmly in
position.
For mooring or storing the boat with the outboard
tilted, a tilt support is provided to support the out-
board.
IMPORTANT: The tilt su pport must not b e used
to support the outboard while trailering.
