6. OPERATION (POWER TRIM/TILT TYPE)
XRTA type outboard (refer to page 20)
The power trim/tilt system can adjust
the motor angle while cruising, or the
motor tilt angle while mooring. Motor
trim angle adjustment is necessary to
compensate for boat load or weight
distribution, water conditions, pro-
peller or engine condition. The motor
trim angle can be adjusted while
accelerating or cruising to obtain the
maximum boat sp'eed, optimum boat
stability, and fuel economy. Under
normal conditions, the boat will
achieve optimum boat performance
when the motor is running at maxi-
mum rpm and the ventilation plate is level
with the water.
Press either the UP or DN portion of
the power trim/tilt switch and trim the
motor to the best position for the
cruising conditions.
The power trim/tilt system operates
when the switch is pressed.and it stops
when the switch is released.

INOTlcEI Excessive trim/tilt angle
during operation can cause the pro-
peller to raise out of the water and
cause propeller ventilation and
engine over-revving. Excessive
trim/tilt angle can also damage the
water pump and overheat the
engine.
To trim motor up slightly, press the
Up portion momentarily.
To trim motor down slightly, press the

Decrease the trim angle on high speed
turns to reduce the possibility of propel-
ler ventilation.
Improper motor trim angle can result in
an unstable steering condition. The
power trim/tilt warning system will be
activated and an intermittent buzzer
sounds when the motor is trimmed
excessively (refer to page 65).
