AUTO TRIM II
SERVICE MANUAL NUMBER 28
“Manual” Mode Operation
Placing the mode switch in the MANUAL position will deactivate the AUTO system and allow
the operator to adjust sterndrive unit position, using the manual trim control. Typical controls
are shown following. Manual trimming may be desirable to fine tune the trim angle for a
particular water condition or boat load, or in situations where greater control over the trim
operation is needed.
Manual trim control also must be used to raise the sterndrive unit for trailering, beaching,
launching and shallow water operation. Ignition switch must be in the RUN position for
manual trim control to function.
RAISING STERNDRIVE UNIT TO TRAILER POSITION

NOTE: Some power trim pump motors are protected from overheating by an internal circuit
breaker. If trailering switch(es) are held depressed after sterndrive unit reaches end of
upward travel, internal circuit breaker will open and pump will stop. If this should happen,
release switch(es) and allow motor to cool for approximately 2 minutes. Once motor is cool,
circuit breaker will reset automatically, and trim operation may be resumed.
CAUTION
DO NOT run engine above idle rpm with unit raised for shallow water operation, as
sterndrive unit is out beyond gimbal ring support flanges and has no side support.
USE EXTREME CAUTION WHEN OPERATING BOAT WITH STERNDRIVE UNIT
RAISED.
