ADJUSTMENT

TRIM ANGLE ADJUSTMENT
To help maintain steering stability and good
performance, always maintain the proper trim
angle as shown in the illustration. The appropri-
ate trim angle varies depending on the combi-
nation of the boat, engine, and propeller, as well
as operating conditions.
• Trim angle too small (Boat tends to "plow")
• Trim angle too large (Boat tends to "porpoise")
• Proper trim angle
Trim range
20
Make a test run in the boat to determine if the
trim angle needs to be adjusted. Adjust the trim
angle using the Power Trim and Tilt system.
Tilt range
Refer to the POWER TRIM AND TILT section.
If you still cannot achieve good performance,
there may be a problem with engine mounting
height. Consult your dealer for assistance.
V WARNING
Trim angle greatly affects steering stability. If
the trim angle is too small, the boat may
"plow" or "bow steer". If the trim angle is too
large, the boat may "chine walk" from side to
side or "porpoise" up and down. These condi-
tions, which result in loss of steering control,
can cause occupants to be thrown overboard.
Always maintain proper trim angle based on
the combination of your boat, engine, and pro-
peller, as well as operating conditions.
V WARNING
When the motor is tilted beyond the maximum
trim position, the swivel bracket will not have
side support from the clamp bracket and the
tilt system will be unable to cushion the
engine if the lower unit strikes an obstruction.
This could lead to occupant injury.
Do not operate the engine above 1500 r/min or
operate the boat in a planing attitude with the
motor tilted beyond the maximum trim posi-
tion.
NOTICE
If you operate the boat with the motor trimmed
beyond the maximum trim position, the water
intake holes may be above the water line,
causing severe engine damage due to over-
heating.
Never operate the boat with the motor
trimmed beyond the maximum trim position.
