(up).
–
To lower the bow (trim-in,
press the switch
DN
(down).
Make test runs with the trim set
in different angles. When the boat
feels well-balanced, easy to steer
and pleasant to operate, then the
optimal trim angle for the boat is
achieved.
Adjusting the boat trim
A bow-up attitude results in less
drag, greater stability and efficiency
when the boat is on plane. With
the bow up, the boat can have a
tendency to steer to one side or the
other, requiring compensational
steering adjustments. To help
offset this effect, the trim tab can be
adjusted. It is easier to accelerate
from a standing start onto plane
when the bow of the boat is down.
Bow up
Too much trim-out or up can:
–
Lift the bow higher out of the
water.
–
Generally increase top speed.
–
Increase clearance over
submerged objects or a
shallow bottom.
–
In excess, can cause boat
porpoising (bouncing) or
propeller ventilation.
–
Cause engine overheating if
any cooling water intake are
above the waterline.
