6. OPERATION (POWER TRIM/TILT)
INOTICE~
Excessive trim/tilt angle during
operation can cause the propeller 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 DN portion momentarily.
Decrease the trim angle on high speed
turns to reduce the possibility of
propeller ventilation.
Improper motor trim angle can result in
an unstable steering condition.
