Power Trim; Trimming Outboard Out (Up) Will; Trimming Outboard In (Down) Will; Tilting Outboard Manually - Mercury 50 User Manual

Keep a tight grip on the steering wheell
tiller handle, especially when changing
speed or trimming boat and outboard. Trim
outboard after reaching cruising speed.
While trimming, steering loads will vary
and will pull in one direction until a bal-
anced condition has been attained. If the
outboard is trimmed past the balanced
steering condition, the steering wheell
tiller handle will then have a tendency to
pull in the opposite direction. Excessive
and, in most boating applications, a de-
crease in performance.
OPERATION
with a trinlitilt sw~tch which tilts the out-
board (up) and in (down). Refer to
QUICKSILVER SIDE MOUNT REMOTE
CONTROL COMPONENTS.
If outboard will be operated in shallow
water with outboard trimmed beyond 20"
trim limit, follow these precautions:
DO NOT operate outboard above 2000
trim limit the swivel bracket will not
have side support.
Check that water level is above water
intake ports to avoid overheating or water
pump impeller damage.
Outboard can be trimmed beyond 20" limit
for launchrng, trailering, shallow water
operation, etc.. if engine speed does not
exceed 2000 RPM.
-
To trim/trlt outboard out (up) push up on
switch.
-
To trim/tilt outboard In (down) push
down on switch.
-
To trim/tilt outboard beyond 20" limit
decrease engine speed to less than 2000
RPM and push up on switch

Trimming Outboard Out (Up) Will:

Lift bow of boat
Generally increase top speed
Transfer steering torque harder to left on
standard or slightly elevated transom
height installations.
lncrease clearance over submerged
objects.
In excess, cause porpoising and/or ven-
tilation.
Cause overheating if trimmed out (up)
beyond water pickup.
Some high speed hulls may become un-
stable if outboard is trimmed too far out
(up). To correct such instability, reduce
power GRADUALLY and trim outboard
ting power too quickly may momentarily
create even greater instability.

POWER TRIM

(Continued)
Trimming Outboard I n (Down) Will:
Result in quicker planing off, especially
with heavy loads.
Generally improve ride in choppy water.
lncrease right hand steering torque
In excess, cause boat to veer to left or
right (bow steer).
Unsafe steering conditions may result at
high speeds with the outboard trimmed all
the way i n (down). Test your boat for
changes i n handling whenever trim angle
is changed.
CHECKING OIL LEVEL
Check power trim oil level periodically as
follows:
DO NOT open fill screw while outboard is
i n (down) position. The reservoir is under
pressure and oil may blow out of fill hole.
Tilt outboard full out (up) position and
engage tilt lock lever (Refer to OUT-
BOARD MOTCIR INSTALLATION.)
Remove f! I cap from trim pump reser-
Fluid level should be to bottom of
threads in fill t;ole; if not, add Quicksilver
Power Trim Steering Fluid or; Automo-
tive Transmission Fluid (ATF) Type F, FA
or Dexron II
Reinstall fill cap

TILTING OUTBOARD MANUALLY

Should the power t r l n system become
Rotate man~lal tilt release valve turns
to the left (counterclockwise).
Grasp outboard using "finger grip
wells" at rear of top cowl and tilt outboard
either up or down manually. Rotate manual
tilt release valve full right to hold outboard
at desired tilt position.
Before operating outboard manual release
valve must be turned fully clockwise.
