Set Trim Limit
e Trim Limit Setpoint function allows a technician to limit the range of the
sterndrive’s trim movement. When the trim position reaches the Trim Limit
Setpoint the PCM will disable the trim limit relay in order to restrain the stern-
drive mechanism from further advancement.
Perform the following steps to read and change the Trim Limit Setpoint.
• This test should be performed with Key-On and Engine Off.
1) Review the advisory message stated above prior to performing this function.
2) Aer selecting the “Set Trim Limit“ function from the PCM Functions menu
the scanner will ask you to conrm if you would like to proceed with the trim
limit adjustment. Press YES to continue or NO to exit.
3) Aer pressing YES you will be asked to physically trim the stern drive to the
upper trim limit position using the boat’s trim controls. Aer trimming the
drive to the desired position press YES to proceed. You may press the NO key
to exit if desired.
4) You will now be prompted to store the new trim limit position. Press the YES
key to proceed. e scanner will program the new setpoint into the PCM’s
memory and you will then be prompted to cycle the ignition switch OFF for 5
seconds to complete the procedure.
Set Trailer Limit
Similar to the Set Trim Limit function described above, some MerCruiser
systems allow the trailering position of the sterndrive to be set. is position is
above the Trim Limit setpoint and is the upper limit of the sterndrive for traile-
ring situations. When proceeding to set the trailer limit the setpoint will rst be
reset to 100% (maximum range) and then allow you to set a new limit. Follow
the scan tool’s on screen prompts to complete the procedure.
