Synchronizing Engines - Mercury 350 MAG Manual

4. Troll button ‑ Pressing the "TROLL" button activates troll control. The troll control feature allows the boat operator to set the
engine speed for slow speed cruising or maneuvering. To activate, move the control handles into forward detent and press
the button. Use the ‑ or + buttons to decrease or increase speed, up to a maximum of 1000 RPM. If troll control is set at a
desired speed and then shut off, the system remembers the set speed and will return to that speed when reengaged. To turn
off the troll control press the "TROLL" button, move the throttle to a different speed, or shift the engine into neutral.
5. Transfer button ‑ Pressing the "TRANSFER" button allows engine operation to be transferred from a different helm. Refer to
Helm Transfer.
6. Dock button ‑ Pressing the "DOCK" button initiates docking mode. Docking mode reduces throttle capacity to approximately
50% of normal throttle. To turn off docking mode, shift the engine into neutral and press the "DOCK" button.
7. Throttle only button ‑ Allows the boat operator to increase engine RPM for warm‑up, without shifting the engine into gear. To
engage throttle only, move the control handle into the neutral position. Press the throttle only button and move the control
handle ahead to the forward detent. The horn will sound once and the neutral light will start flashing. The horn will sound twice
when throttle only is engaged. Advance throttle to increase engine RPM. To disengage, return control handle to neutral
position and press the throttle only button. Engine RPM is limited to prevent engine damage.
8. 1 lever button ‑ Pressing the "1 LEVER" button initiates single lever mode. Single lever mode enables the throttle and shift
functions of both engines to be controlled by the port control handle. To turn off single lever mode, shift the engine into neutral
and press the "1 LEVER" button.
9. Sync button ‑ Pressing the "SYNC" button turns off or on the auto synchronization feature. Refer to Synchronizing
Engines.

10. Control handle tension adjustment screw ‑ This screw can be adjusted to increase or decrease the tension on the control
handle (cover must be removed). This will help prevent unwanted motion of the handle in rough water. Turn the screw
clockwise to increase tension and counterclockwise to decrease tension. Adjust to tension desired.
11. Detent tension adjustment screw ‑ This screw can be adjusted to increase or decrease the effort to move control handle out
of detent positions (cover must be removed). Turning the screw clockwise will increase tension. Adjust to tension desired.
