Mercury 135 Verado Manual page 92

Operating the boat at high speeds with the outboard trimmed
too far under can create excessive bow steer, resulting in the
operator losing control of the boat. Install the trim limit pin in a
position that prevents excessive trim under and operate the
boat in a safe manner.
• In rare circumstances, the owner may decide to limit the
trim in. This can be accomplished by purchasing a stainless
steel tilt pin from your dealer and inserting it in whatever
adjustment hole in the transom brackets is desired. The
non‑stainless steel shipping bolt should not be used in this
application other than on a temporary basis.
2. Trimming 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.
• Increase steering torque or pull to the left at a normal
installation height (with the normal right hand rotation
propeller).
• In excess can cause boat porpoising (bouncing) or
propeller ventilation.
• Cause engine overheating if any cooling water intake holes
are above the water line.
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.
