Active Trim Operation - Mercury SC 1000 Operation And Maintenance Manual

At boat startup, Active Trim resumes the on/off state from the previous shut
down. For example, if Active Trim was on at the previous shut down, it will be
on at the next startup.
GPS
Active Trim uses a GPS signal to determine vessel speed. The Active Trim
system will not automatically control trim until the GPS unit has acquired a
signal.
SHALLOW WATER OPERATION
Active Trim cannot detect water depth and will not trim up automatically in
shallow water. The boat operator will need to override Active Trim by trimming
the engine or drive manually or pressing the OFF button.
TRAILER POSITION AND ACTIVE TRIM
Placing the engine or drive in the trailer position (over 50% of the adapted trim
range) will prevent the Active Trim from engaging. Any time the engine or drive
is trimmed above its normal range—to navigate shallow water, launch the boat
from a trailer, or load the boat onto a trailer, for example—you must manually
trim down before Active Trim will function. This safety feature is meant to
prevent the engine or drive from automatically trimming down and hitting
something.

Active Trim Operation

The Active Trim feature can be turned on or off from the tachometer display
screen. The gauge has a range of five user adjustable trim profiles. This allows
the operator to fine tune the trim curve during boat operation to compensate for
differences in environmental conditions or boat loading. If there is not enough
adjustment to get the boat to trim properly, a major profile adjustment may
need to be made. Refer to Active Trim Setup and Configuration.
