• If in excess, lower the bow of some boats to a point at which they begin to plow with
their bow in the water while on plane. This can result in an unexpected turn in either
direction called bow steering or over steering if any turn is attempted or if a significant
wave is encountered.

SINGLE ENGINE TRIM/TRAILER
Single engine applications will have a button that can be pressed to trim the sterndrive unit
up or down.
To raise the sterndrive unit for trailering, beaching, launching, low speed (below 1200 rpm),
and shallow water operation push the trim button to raise the sterndrive unit to the full up/
out position.
Some controls also have a trailer button that trims the sterndrive to a position suitable for
trailer purposes only.
NOTE: The DTS control system limits the extent to which the sterndrive unit can be trimmed
up/out when engine speed is above 3500 RPM.
DUAL ENGINE TRIM/TRAILER
NOTICE
If using external tie bars, raising or lowering the drives independently of each other can
damage the drive and steering systems. If using an external tie bar, raise and lower all
drives together as a unit.
Dual engine applications may have a single integral button to operate both sterndrive units
simultaneously or may have separate buttons for each sterndrive unit.
Some controls also have a trailer button that trims the sterndrives to a position suitable for
trailer purposes only.
Trim without Key
Trim without key is a method of allowing trim operation after the ignition key switch is turned
off. The command module and PCM remain powered and are able to process trim requests
for up to 15 minutes after the key switch is turned off. The command module does not
process any requests other than trim during this period. Once the 15 minute period expires,
the command module sends a command through the CAN lines to shut down the PCM.
On multi‑engine applications, the timeout is managed seperately for each engine.
The trim without key period may be ended at any time by moving the control handle to Wide
Open Throttle Reverse (WOTR) with the key off. To end the 15 minute period for the center
engine in a shadow mode application, ensure all ignition key switches are in the "OFF"
position and both remote control handles are in the Wide Open Throttle Reverse (WOTR)
position.
