WARNING
Engine T rim
The power trim & tilt system allows you to raise and
lower the engines for optimum performance in the water
and for trailering, launch ing and beac hing. The switch es
are a momentary type switch ; co nstant pressure must
be applied to the switch during the raising and lowering
cycl
e.
The trim switch es are loca ted on a co ntrol pad at the ce nter
of the co ntrol co nsole. The engines ca n be individually
trimmed by pressing the appropriate co ordinating switch .
All engines ca n be trimmed at the same time by pressing
the “ AL L ” switch on the co ntrol pad or the trim switch
loca ted on the port throttle co ntrol lever.
Certain comb inations of engine trim angle, b oat
op erating angle, and b oat sp eed can reduce
your forward- facing visib ility. Reduced op erator
visib ility can contrib ute to collisions, causing
serious injury or death.
Trimming the engines down or in is best for acce leration
and ca rrying heavy loads. The boat ride tends to be
slower and wetter, and the boat might bow steer.
Trimming the engines up or out incr eases boat
performanc e and fuel eco nomy. E xce ssive trim angle
will reduce boat performance . E xce ssive trim angle
might ca use propeller ventilation and engine over-speed
alarms.
Ex cessive engine trim angle can cause the b oat
to “p
orp oise” or b ounce. Porp oising can reduce
op erator control and visib ility, resulting in unsafe
b oat op eration.
